polyurethane adhesive vs epoxy

Years ago, the common practice was to chunk out both sides of the crack, essentially making it larger, then using hydraulic cement to fill the void. Polyurethane is also a polymer material that contains urethane linkages. Its color can fade after some several years. Prior to that, Sean worked in the construction industry, specializing in contract and project management for commercial and industrial floor and roof projects. The key difference between epoxy and polyurethane is that the epoxy contains epoxide groups whereas polyurethanes contain urethane linkages. The urethane linkage forms when the –N=C=O group of isocyanate react with the –OH groups of alcohol to form a urethane linkage (-NH-C(=O)-O). It’s not a matter of choosing one over the other, but a matter of utilizing both to achieve the desired result: Epoxy primers for bonding the system to concrete, epoxy build coat(s) for total system build/thickness, and polyurethane topcoats for enhanced physical performance, chemical-resistance, safety and aesthetics. It’s cheap. In the application point of view, the main difference between epoxy and polyurethane is that the epoxy resins can resist moderate temperatures while the polyurethanes can withstand high temperatures. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } Polyurethanes provide the enhanced performance characteristics that protect the entire system. Today – the words are used commonly for both. Although it cannot be used as a complete adhesive, some of the multiple products must be added to it to make it an adhesive. Epoxy and polyurethane are booth chemical resins with different reaction profiles and physical properties. Take our FREE Flooring Self-Assessment today! Polyurethanes are the “icing on the cake”. These polymers get their name according to the repeating linkages present in the polymer material instead of the monomers used for the production. Terms of Use and Privacy Policy: Legal. Increased Impact and Abrasion Resistance: Polyurethanes exhibit excellent impact and abrasion resistance, providing up to four times longer life than uncoated epoxy floors. Or else, epoxy resins can react with some other compounds such as; These are co-reactants. Show comparatively low resistance towards organic acids, Shows high resistance towards corrosion, inorganic acids, alkali solvents, organic alkalis and many other solvents. They offer chemical resistance and waterproofing. These monomers combine with each other to form a polymer. Urethane wears faster than epoxy. 1. With the number of advantages polyurethanes have over epoxies, why would one choose one coating technology over the other? Upon curing, the epoxy build coat(s) provide a hard, durable surface. There are occasions, especially in lighter colors where epoxy can yellow under the urethane. Finishes: Polyurethane finishes can range from satin to semi-gloss to high-gloss. These urethane adhesives are durable and highly elastic for applications requiring energy absorption and flexibility between many dissimilar materials. “What Are Epoxy Resins?” ThoughtCo, ThoughtCo. Previously, the term "glue" was used exclusively for natural adhesives (boiled horse hooves, etc…) and "adhesive" was used for synthetic products. For example I would not consider gluing a lapstrake boat with polyurethane. Epoxy and urethane are used to bond surfaces together. One practice was to make the crack large enough to insert a pipe to drain th… Though they exhibit much thinner cured-film thickness, polyurethanes offer a number of unique advantages over epoxies. Available here, 1.’Epoxy’ By Dzhang2680 – Own work, (CC BY-SA 3.0) via Commons Wikimedia  I’ve been researching products on your website. “I thought all floor coatings were ‘epoxy’,” the facility manager quips. Our epoxy, with urethane topcoat, is designed to be UV resistant. Polyurethane is another resin for floor coating concrete and steel. For concrete floor coating applications, the most durable, longest-lasting coating systems usually include the use of both epoxy and polyurethane. Figure 02: A Chair made from Polyurethane. Build/Thickness: Epoxy build coats are typically installed at 8 to 15 mils per application. These range from flexible epoxies, to chemical-resistant epoxies, to fast-setting epoxies, etc. Polyurethanes can withstand high temperatures. 2.’Polyurethane chair, Walker Art Gallery’ By Reptonix free Creative Commons licensed photos (CC BY 3.0) via Commons Wikimedia. Available here  They are both light reflective, easy to clean, and long lasting. Within the acrylic anchoring adhesives product category, we offer AT-XP® adhesive. When a component becomes dislodged, replacement is a good solution, but sometimes you need a faster solution until you can get to the repair shop. We love epoxy, as you will know if you’ve spent any time on this site, but the first type of glue that gets considered in wood working projects is usually poly-vinyl acetate (PVA) wood glue and for good reasons. In emergency repair of wet wood, polyurethane is the adhesive of choice, as long as the parts are kept together with clamping or with temporary screwing. In fact, the lifespan of the PU system is roughly double that of the epoxy, clocking an impressive ten-year’s compared to the epoxy’s five. “What’s the difference with epoxy vs polyurethane coatings?”. Within this group of products we have properties including excellent UV and weather resistance, abrasion resistance, high heat and chemical resistance and also flexible products used as membrane systems for both foot and vehicular traffic. These polymers form via glycosylation of aliphatic alcohols or polyols. He has over 15 years of marketing and sales support experience in the protective coatings industry. Whilst a polyurethane system will initially cost more compared to an epoxy, it is far more cost effective in the long term. This polymer material is linear and is semi-solid crystalline materials. When used as a topcoat over epoxy, they protect the underlying epoxy from yellowing over time. 7875 Bliss ParkwayNorth Ridgeville, Ohio 44039, info@protectpoly.comWe reply within 24 hours, Sean Walsh is the Marketing & Product Development Manager of Protective Industrial Polymers, a company that manufactures high-performance resinous floor coatings for industrial manufacturing environments, which has a keen focus on developing unique solutions for managing electrostatic, microbial, chemical, explosion and safety risk concerns. Epoxy primer can be applied on either new bare or old rusty metal surfaces and is compatible with top coats made up of other substances. From a form and function standpoint, epoxies are very good at three things: On the other side of the coin, epoxies are sensitive to UV light so they will amber or yellow over time when exposed to sunlight. There are certainly different types of epoxy coatings formulated to address a different desired performance result. We recommend concrete preparation by mechanical means, such as diamond grinding or abrasive shot blasting methods. We call this term sometimes as “epoxide number”. Resin vs Epoxy: below is a list of these main resin categories: Polyester Resin: This is not an actual epoxy but is rather an unsaturated synthetic resin; Epoxy Resin: This type is supplied in 1 or 2 component forms; Polyurethane Resin: This is also not an actual epoxy but is rather a synthetic resin or plastic Here we use bisphenol F in the place of bisphenol A, but the way of formation of the polymer is same as the bisphenol A epoxy resin (as discussed above). It is a form of polyurethane. In fact, in many cases, if the epoxy primer and build coats are well-bonded, a simple re-coat of the polyurethane topcoat may be all that is required every few years, depending upon use. A complete coating system is only as good as its initial bond to the concrete substrate. Adhesives are often also required to take on some of their partner’s qualities and become sealing agents, mainly to ensure the bond it makes when it binds two substrates together will last. Epoxy or epoxy resin is a class of polymer material consisting of epoxy functional groups. Is Floor Cleaning and Maintenance Part of Your Safety Program? Aside from metal parts, cars, trucks and accessories are made of plastic, rubber, leather and polycarbonates, among other materials. This creates a well-adhered system base that will allow subsequent build and topcoats. The conversation usually starts off something like this: “I need you to take a look at my concrete floor,” the facility manager says. Moreover, polyol also should have at least two hydroxyl groups per molecule. Epoxy and polyurethane are great for protecting your floor against stains, damage, chemicals, oils, and wear. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Epoxy ; Polyurethane Glue; Hide Glue; Poly-Vinyl Acetate (PVA) Wood Glue: Cheap & Cheerful. I would use epoxy. PU systems also benefit from their increased wear, abrasion and impact resistance properties. “Polyurethanes.” The Essential Chemical Industry Online. I would put most of my structural work together using Epoxy or Resorcinol glue. Which coating would you recommend?”. Some other names for these co-reactants are hardeners or curatives. Therefore, the cross-linking reactions that epoxy resins undergo with these curatives refers to “curing”. Epoxy and urethane are used by foam and adhesive industries to bond surfaces. The crack was larger, thereby reducing the structural integrityof the foundation. The difference between epoxy and polyurethane is that the epoxy resin contains epoxide groups whereas polyurethanes contain urethane linkages. Epoxy Benefits. Polyurethane glue has a lot of the same qualities as epoxy without the disadvantage of requiring the mixing of a resin and hardener. Although the name polyurethane gives an idea that the polymer consists of urethane monomers, it in fact, consists of urethane linkages, not monomers. Proper Floor Cleaning and Maintenance Can Help Ensure Longer Service Life. Firmness and flexibility are important. An epoxy primer cannot withstand UV ray as good as urethane. Polyurea systems use urethane-based technology throughout the entire system and provide outstanding UV resistance. 1. 4. Epoxy adhesives, methacrylate adhesives, urethane adhesives…what are they? “It’s bare concrete and we need it to be durable, bright, safe and easy to clean. There are a number of different epoxy floor coatings on the market today, with costs that are all over the map. They are all 2-part structural adhesives, but … However, there is one downside to epoxy primer. Let us have a look at the use of Epoxy in various type of places: The first and most important use of epoxy resin is that it is used as an adhesive. However, there are some plant-derived sources as well. We can leave those intracacies for another blog article. The ratio between the number of epoxy groups and the mass of the polymer material gives the specific amount of epoxide groups in an epoxy resin. Bonding to Concrete: Provided the concrete substrate is properly prepared to receive a coating, epoxies are excellent for mechanically bonding to concrete. Side by Side Comparison – Epoxy vs Polyurethane in Tabular Form Is there a difference between epoxy glue and adhesive? Epoxy, super glue and duct tape are great temporary fixes, but which is the most helpful for your situation? Epoxy is not resistant to ultraviolet light so, while it will not change color immediately, the epoxy will begin to yellow after several months or years. The monomers for polyurethane are polyols and isocyanates. Polyurethane is a polymer material that has urethane linkages (carbamate linkages). Both epoxy and polyurethane are polymer materials. Epoxy vs polyurethane is a common topic brought up during my conversations. Optional wear and safety additives can be incorporated into the topcoat texture. Of course, concrete preparation is a crucial part of establishing a proper bond. Where epoxies might typically achieve 34.5 MPa/5000 psi with 3 percent elongation at room temperature, urethanes are on the order of 20.7 MPa/3,000 psi with 75 percent elongation. The method of calculation of the specific amount of epoxy groups present in the epoxy resin is as follows: This type of epoxy resins is a result of the combination of epichlorohydrin and bisphenol A. this combination gives bisphenol A diglycidyl ethers. Why is Planet Earth Your True Friend for ESD Grounding? Additionally, the offer excellent resistance to staining from hot or cold tires. What is Epoxy Installation & Performance: Upon curing, the epoxy build coat(s) provide a hard, durable surface with good impact resistance. Epoxy creates a hard protective coating that bonds to concrete or steel. Urethane, which is resistant to ultraviolet light, will remain the same color for a much longer time than epoxy. It is recommended that materials be clamped during curing which occurs in approximately four hours (Note: Check the manufacturers cure time on the packaging as some polyurethane glues have cure times as long as 24 hours). Though epoxy is strong, it will crack on surfaces that frequently move. These two components are thoroughly mixed together, applied to the concrete floor, and allowed to cure. Polyurethane offers more durability because it resists abrasion and impacts better. Summary. Overview and Key Difference This sealing role usually involves waterproofing the bond, protecting it from loosening because of dynamic loads, and lessening the chances of bonds deteriorating due to oxidation and corrosion. Flexibility. The key difference between epoxy and polyurethane is that the epoxy contains epoxide groups whereas polyurethanes contain urethane linkages. In the application point of view, the main difference between epoxy and polyurethane is that the epoxy resins can resist moderate temperatures while the polyurethanes can withstand high temperatures. This chemical protects against damage, UV rays, and water. The primary use of epoxy resin is for adhesive purposes. Epoxy resins can react with each other via catalytic homopolymerization and form cross-links between them. Often, I receive a call from a facility manager who has been tasked with coating his or her production floor. 2018. Lazonby, John. As polyurethane is more durable than rubber, it can be used in cases of high stress and offers a certain amount of … In the industrial floor coating world, while epoxies and polyurethanes are both thermosetting polymers, their differences in function and performance are vast. Epoxy resins can resist moderate temperatures. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry. 3. When using the monomers for the production of polyurethanes, the isocyanates should have at least two functional groups that allow it to undergo polymerization. Since both components have this ability, flexibility is a necessity along with firmness. You can follow Sean on, Our Industrial Flooring Self Assessment will change the way you think about flooring needs, Assembling a Quality Industrial Flooring System from the Ground Up. Epoxies are a type of polyurethanes. Polyurethane vs Rubber Flexible and elastic properties go to both of these options and each substance is used in the automotive industry, in the manufacture of certain parts. So which adhesive type is the best? What is Polyurethane In the industrial scale productions, mostly petroleum oil is the primary source for epoxy resin production. Polyurethane is a polymer material that has urethane linkages. Isocyanates and polyols undergo polymerization to form a polyurethane. Novolac epoxy resins form when phenols react with formaldehyde and undergo glycosylation with epichlorohydrin. It depends upon the type of composite and the desired assembly process and the requirements of the composite bond. Cyanoacrylates, Epoxy Adhesives, Polyurethane Adhesives, Structural Acrylic Adhesives and UV Cure Adhesives all bond well to composites. Epoxy or epoxy resin is a class of polymer material that consists of epoxy functional groups. It’s not a matter of choosing one over the other, but a matter of utilizing both to achieve the desired result: Epoxy primers for bonding the system to concrete, epoxy build coat(s) for total system build/thickness, and polyurethane topcoats for enhanced physical performance, chemical-resistance, safety and aesthetics. Depending on the desired performance requirements and condition of the concrete, more build coat applications may be desired. Of the two, epoxy is a higher-strength substance that prevents a surface from moving. Epoxy adhesives can be selected instead of polyurethane adhesives because they are characterized by greater thermal strength and a longer “working life” (30–35 min) which allows the bonding of larger size pieces with less chance for wastage; their higher cost is partly offset by the smaller quantity required. Johnson, Todd. Because of the inherent flexibility of the urethane chain, it is the adhesive of choice in low temperatures where epoxies and methacrylates may become too stiff and brittle. This polymer material has a low viscosity at room temperature. They are also not as abrasion and chemical-resistant as polyurethanes. Epoxies are fairly easy to install, exhibit ample working time, and are fairly cost-effective when compared to other industrial flooring solutions. The term epoxy is used to name epoxy resins that consist of epoxy functional groups in a repeating pattern. What adhesive types are best for bonding composites? When it comes to epoxy vs polyurethane coatings, the important take-away is to realize that both product technologies work well in conjunction with each other to produce a durable, long-lasting flooring solution. 2. Protective Industrial Polymers is a unique company devoted to providing turn-key flooring solutions for today's industrial marketplace. The monomers for epoxy resins are phenols and epichlorohydrin, but the monomers may vary depending on the type of epoxy resin. Epoxy is an excellent adhesive to use for concrete surfaces. Compare the Difference Between Similar Terms. Sean enjoys working closely with PIP’s sales and management group to develop and market new flooring products and systems to address end-user’s unique requirements. All rights reserved. The evolution of sealing cracks technology over the last decade has been astounding. “For a general industrial or commercial application, the vast majority of the time I would recommend, at minimum, a three coat system consisting of an epoxy primer, an epoxy build-coat and a polyurethane topcoat,” I respond. If we increase the amount of bisphenol A (compared to epichlorohydrin), it provides high molecular weight polymer material. Epoxy and urethane are important components in the adhesive and foam industries. 3. The Use Of Epoxy. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. In very simple terms, a typical two-part epoxy coating contains a resin side and a hardener side. These polymers can be either low molecular weight or high molecular weight polymers with at least two epoxide groups. Even though epoxy is harder, the flexibility afforded by PU is valuable in many industries. 2. Most of the times, this polymer material shows high chemical resistance and high-temperature resistance but low flexibility. 5. It is said that epoxy offers higher strength than urethane. Epoxy vs Polyurethane. Within the epoxy anchoring adhesive products category, we offer SET-3G™, SET-XP® and ET-HP® adhesive anchors. This practice over time made things worse. Overall, epoxies are the preferred materials for priming properly prepared concrete substrates, and providing ‘build’ or film thickness that can hide small blemishes or hairline cracks on the concrete surface. This thickness allows the coating to chemically bond to the epoxy primer, and is thick enough to self-level and fill minor concrete blemishes and hairline cracks. The reactions between the monomers in this polymerization are an exothermic reaction in which heat is given off from the reaction mixture. A polymer is a macromolecule that contains a large number of small repeating units (monomers). Not sure what type of polymer floor coating system your facility requires? The crosslinking process forms a thermosetting polymer that has favorable chemical and mechanical properties. Durability Both epoxy and acrylic adhesives come in a two- cartridge system consisting of a resin paired with a hardener (for epoxy) or an initiator (for acrylic).

Chemical-Resistance: Polyurethanes are resistant to a broader range and concentrations of chemicals. “Epoxy.” Wikipedia, Wikimedia Foundation, 19 Apr. Epoxy is a strong adhesive or glue that does essentially not expand. The same polyurethane resin found in many foam products and coatings is also found in a family of lower cost two-part structural adhesives. UV Stability: Polyurethanes exhibit excellent UV-resistance. Polyurethane coatings produced by Hychem are varied, consisting of water-based, solvent based, 100 percent solids and cementitious products. PU also resists damage from many different threats well, including solvents, alkalis, and sources of corrosion. Epoxy vs Methacrylate vs Urethane Adhesives.
