We also have crack and spall epoxy-based products that are USDA approved for meat and poultry plant-based applications. There are a number of different epoxy floor coatings on the market today, with costs that are all over the map. La résine époxy peut être dangereuse si on ne la manipule pas avec précaution. “It’s bare concrete and we need it to be durable, bright, safe and easy to clean. Polyurethane two-component adhesives are divided into different degrees of hardness. 5. When solidify the PU glue, it will lead to some low molecular compounds, which is toxicity, it is bad for health with the bad smell. De manière générale, ce genre de revêtement de sol est utilisé dans le but de couvrir un entrepôt, ou de grands espaces. “Yellow glue makes a bond that is stronger than the wood. Show comparatively low resistance towards organic acids, Shows high resistance towards corrosion, inorganic acids, alkali solvents, organic alkalis and many other solvents. Differences Between Epoxy vs.Polyurethane Thin Film Topcoats By Sophia Daukus on October 17th, 2016 in Commercial & Retail , Installation Epoxy and polyurethane thin film topcoats are two types of high performance floor coatings that can be used to strengthen, protect, and improve the aesthetics of an industrial flooring system. Its thicker formula provides guaranteed results and best quality. 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. These polymers get their name according to the repeating linkages present in the polymer material instead of the monomers used for the production. However, using an epoxy-based resin will ensure that the product cures hard and bonds securely to the surface. Epoxy resins can react with each other via catalytic homopolymerization and form cross-links between them. “Polyurethane glues stick well and hold odd materials, but they generally aren’t stronger than yellow glues,” Zimmerman says. These polymers form via glycosylation of aliphatic alcohols or polyols. However, if you only focused on the point, you must be wondering if there is any difference between the two types of glues. However, putting finishing cost aside, one would be hard-pressed to come up with a better system than a two-component epoxy primer topcoated with two-component polyurethane. Prior to that, Sean worked in the construction industry, specializing in contract and project management for commercial and industrial floor and roof projects. Résine époxy VS Polyuréthane : avantages et inconvénients. Polyurethanes can withstand high temperatures. “Polyurethane glue is not foolproof,” says Zimmerman with Franklin International. Good Info. There’re 3 kinds glues, they are epoxy resin glue, PU (polyurethane) glue and silicone glue. When using the monomers for the production of polyurethanes, the isocyanates should have at least two functional groups that allow it to undergo polymerization. Epoxy-like strength - No mixing. “Polyurethanes.” The Essential Chemical Industry Online. Les peintures polyuréthanes ou époxys sont bien différentes malgré une similarité apparente. “Yellow glue makes a bond that is … Both epoxy and polyurethane are polymer materials. Epoxy and urethane are important components in the adhesive and foam industries. 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. Polyurethanes do not bond well to concrete and do not exemplify the self leveling properties that epoxies do when applied to on these surfaces. A good alternative is epoxy resin glue. Johnson, Todd. 9. In most cases, some surface treatment of the bonded parts, such as corona, low-pressure plasma, or flame treatment, is needed. Even though epoxy is harder, the flexibility afforded by PU is valuable in many industries. Its thicker formula provides guaranteed results and best quality. Colle epoxy . It is formed when isocyanates react with water or polyetheramines to create a urea linkage. My favorite way to use epoxy glue is to use quick curing epoxy glue to fill in cracks on projects where the surface isn’t smooth for some reason. This practice over time made things worse. Available here  A distinction is made: Adhesives that are designed for high loads and must have a high shear strength; I think one should view more actual application videos. In the industrial floor coating world, while epoxies and polyurethanes are both thermosetting polymers, their differences in function and performance are vast. We have meticulously assembled complete systems that will cover what we state and beyond. Choosing the wrong resin for your project could result in a ruined project. The most common mixing ratios of adhesive to hardener are either 100:15 or 100:30. Of course, concrete preparation is a crucial part of establishing a proper bond. Available here, 1.’Epoxy’ By Dzhang2680 – Own work, (CC BY-SA 3.0) via Commons Wikimedia  Its setting time is 1-4 hours. It depends upon the type of composite and the desired assembly process and the requirements of the composite bond. Both epoxy and polyurethane are polymer materials. Pour a thin pour coating epoxy too thick and it will result in an accelerated reaction which could crack, yellow or fish eye the epoxy. Epoxy Benefits . Moreover, polyol also should have at least two hydroxyl groups per molecule. Polyurethanes are the “icing on the cake”. Labels et normes en peinture. The monomers for epoxy resins are phenols and epichlorohydrin, but the monomers may vary depending on the type of epoxy resin. Most of the times, this polymer material shows high chemical resistance and high-temperature resistance but low flexibility. 16 thoughts on “Epoxy vs. Polyurethane – Which Will You Choose?” sudhir says: 3rd April 2018 at 10:33 am. They offer chemical resistance and waterproofing. Compare the Difference Between Similar Terms. Résine epoxy et polyuréthane, quelle différence ? 1. It passes ANSI type 1 and 2. Indeed, cost is always an important consideration when choosing finishing systems for products. Bonding to Concrete: Provided the concrete substrate is properly prepared to receive a coating, epoxies are excellent for mechanically bonding to concrete. Like epoxy, polyurethane is a thermosetting polymer as well and is considered a high performance coating. 3M Scotch-Weld™ low-odor acrylic adhesive DP-810 requires minimal surface prep for binding metal hinges into awning frames, reaching handling strength in 10 min. When you expose both epoxy and polyurethane to small quantities of sunlight over some time, epoxy is likely to become yellowish unlike polyurethane which is likely to retain its original tint. check_circle 100% solids. Unlike PVA glue, it bonds well with smooth surfaces such as glass, some plastics and rubber. Thanks Sudhir for your kind comments! These monomers combine with each other to form a … What are the similarities with epoxy vs polyurea? This polymer material is linear and is semi-solid crystalline materials. carl le roux says: 25th April 2018 at 11:53 am. Selon le support à coller, les colles sont dites époxy, néoprène, cyanocarylate, polyuréthane ou encore polymère. 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. 2. Urethane, which is resistant to ultraviolet light, will remain the same color for a much longer time than epoxy. Son application se fait au rouleau, au pinceau ou au pistolet sur un support sain, propre, sec et poreux en 2 couches. Article . Polyurethane glue has a lot of the same qualities as epoxy without the disadvantage of requiring the mixing of a resin and hardener. 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. With the number of advantages polyurethanes have over epoxies, why would one choose one coating technology over the other? Is Floor Cleaning and Maintenance Part of Your Safety Program? These two components are thoroughly mixed together, applied to the concrete floor, and allowed to cure. In very simple terms, a typical two-part epoxy coating contains a resin side and a hardener side. A polymer is a macromolecule that contains a large number of small repeating units (monomers). check_circle Excellent sandability. Novolac epoxy resins form when phenols react with formaldehyde and undergo glycosylation with epichlorohydrin. “What Are Epoxy Resins?” ThoughtCo, ThoughtCo. When used as a topcoat over epoxy, they protect the underlying epoxy from yellowing over time. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. Though they exhibit much thinner cured-film thickness, polyurethanes offer a number of unique advantages over epoxies. 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. We recommend concrete preparation by mechanical means, such as diamond grinding or abrasive shot blasting methods. Epoxy and polyurethane (PU for short) floors are the two most commonly used types of resinous industrial floors. Epoxy vs polyurethane is a common topic brought up during my conversations. Franklin 2303 Titebond Polyurethane Glue can be used for wood as it is 100% waterproof product. On nous demande souvent quelles sont les différences entre l’époxy et le polyuréa. Epoxy is a strong adhesive or glue that does essentially not expand. Polyurethane glue is type of adhesive used in a variety of commercial industries, as well as in hobbies and crafts. 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. 2, The PU (polyurethane) glue is better than epoxy resin glue because of its good yellow degeneration resistance, good Low temperature resistance, but not resistant to high temperature. 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. Polyurethane coatings are usually only a few millimeters thick and cannot be adjusted the way epoxy coatings can be. Additionally, the offer excellent resistance to staining from hot or cold tires. Terms of Use and Privacy Policy: Legal. Installation & Performance: Upon curing, the epoxy build coat(s) provide a hard, durable surface with good impact resistance. Not sure what type of polymer floor coating system your facility requires? For concrete floor coating applications, the most durable, longest-lasting coating systems usually include the use of both epoxy and polyurethane. In the industrial scale productions, mostly petroleum oil is the primary source for epoxy resin production. That all changed with epoxy. Choisir entre une résine polyuréthane comme la peinture sol industriel ou une résine époxy peut être un choix particulièrement difficile. Epoxy is the only glue at the moment which is reliably gap filling. Cyanoacrylates, Epoxy Adhesives, Polyurethane Adhesives, Structural Acrylic Adhesives and UV Cure Adhesives all bond well to composites. We can leave those intracacies for another blog article. The primary drawback with urethane vs epoxy commercial coatings is that urethane may not bond as tightly to concrete as epoxy does. 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. Chemical-Resistance: Polyurethanes are resistant to a broader range and concentrations of chemicals. If you religiously went through the above section, then you can already point out a number of differences between the Super glue and Epoxy glue. This practice over time made things worse. Titebond Polyurethane Glue combines a long 20 minute working time with a short 45 minute clamp time. The only glue joint that I have had fail (other than fixing something while saying "I wonder if this will hold") was the corner of a fairly large mirror frame, done with polyurethane glue.
