If an uncured PU floor is attacked by water or condensation you may get this catastrophic results (like in the picture below). Bond Polychem, Ahmedabad, Gujarat. These coatings are usually sold as finish and are usually applied at 2-3 mils DFT. Most high solids epoxies provide excellent protection against acids and alkalis. I thought Epoxy paint was totaly different. Most novolacs are designed to handle 98% sulfuric acid and 37% HCL for splash & spillage. These coatings can normally handle higher dry service temperatures than epoxies and two component urethanes. Epoxies are extremely easy to apply, allow for varying degrees of thickness (usually between 3-15mils), and give you an extremely durable floor that can withstand the abuse it receives. Acrylic Polyurethanes are usually made with an aliphatic compound which provides the long term stability needed in an Acrylic Polyurethane. As a coating or sealant. (, Based Epoxies are great choices in less demanding areas. (, Both of these epoxies are very high performing epoxies that are ideal for harsh chemicals. It is ideal as an anti-graffiti coating and has outstanding chemical and abrasion resistance. Operational Differences Elastic polyurethane floor paint for a car park 11. or 251-964-7911 for assistance on your upcoming coating project. What are the Best Industrial Coatings for Structural Steel? They are also UV stable meaning when sunlight is exposed on it they will not yellow over time like some epoxies. 1. Polyurethane / Epoxy Floor Coating Our Range Includes Epoxy Paints, Coal Tar Epoxy, Polyurethane Coatings, Stoving Paints, Fast Drying Enamels, Etch Primer, All Types Of Primers, All Types Of Thinners A/D / Stoving / PU Epoxy / Lacquers & Peelable Lacquers Chlorinated Rubber Paints, Tailor Made Anti-Corrosive Coatings & Its Applications. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols. A polymer is a macromolecule that contains a large number of small repeating units . These coatings are made with 100% Polyester resin which provides an extremely durable finish. Polyester Polyurethanes are a true C.R.U. Polyurethane paints also tend to become tacky very quickly due to solvent leaving the paint surface. Here’s some of the different types of Epoxy Coatings: 100% Solids Epoxy: These epoxies generally have very little or no Volatile Organic Compounds (VOCs) and little to no odor. Water and chemical resistance: Resistance to water, steam, moisture, and most chemicals means that PU coating is a waterproof barrier, preventing corrosion of the substrate. COATINGS - ENAMEL PAINT . When applying you will typically mix one part A and one part B together (mix ratios will differ from product to product) to tart the the hardening process. Depending on the product, polyurethanes can have better chemical resistance and provide better abrasion and impact resistance than the epoxies. @siwarak If you are referring to Polyurethane as “PU” these layers can be built on top of one another. Indeed, cost is always an important consideration when choosing finishing systems for products. $50/gallon is relatively cheap for paint considering the cost of some of the alternatives out there. They’re not as high performing as the high solids and 100% solids epoxies but they offer a great solution in areas where there’s no aggressive chemicals. The most expensive stuff I … Unfortunately, it is this same impressive durability that makes it difficult to paint over epoxy … They can also be used as an intermediate coat and top coat due to their durability and impact resistance. Both epoxy and polyurethane are polymer materials. Epoxy Central sells both epoxies and polyurethanes as well as epoxy and polyurethane coating kit. This chemical protects against damage, UV rays, and water. PU systems also benefit from their increased wear, abrasion and impact resistance properties. ". You want a floor that is strong, like your business, and worry-free. Epoxies can be used in a variety of applications from home garages and basements to airplane hangers and commercial grade food processing plants. This is where Polyurethanes comes in to play, which we will discuss later. Re: 2 Part vs. 1 Part Polyurethane Paint? Epoxy should be used as the base coating (to bond to concrete) and the polyurethane can be used as a topcoat (flexible, scratch resistant, UV stable). These epoxies can generally be used on steel, concrete, and galvanized steel. Comments will be approved before showing up. 2. (Chemical Resistant Urethane), which makes it a great choice for aircraft hangars, service bay floors and other high traffic areas due to its resistance to a wide range of chemicals including salt, oil, gas, grease, skydrol, caustic, and most acids that you may come in contact with your floor. Floor Coating Sealers: How to know the difference between them all. To be fair, even industry experts will toss around the word paint to describe the coating material they are applying on a particular job. Hello, It protects the paint from peeling and is easy to clean. They offer chemical resistance and waterproofing. Most H.S. (PC-110, PC-145, PC-149, PC-200), – Cycloaliphatic & Novolac Epoxies: Both of these epoxies are very high performing epoxies that are ideal for harsh chemicals. 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. Is there any benefit or disadvantage to do PU coating on to of PU flooring? Sign up to get the latest on sales, new releases and more …, © 2021 Epoxy Central. epoxies have “fast cure” and “low temperature cure” hardeners that allow for a high level of productivity in the warmer months and the ability to cure down to cooler temperatures in the colder months. The different types of products will give you varying benefits. (MCU-100, MCU-101, MCU-104), – Acrylic Polyurethanes: Acrylic Polyurethanes are known for their excellent gloss and color retention, UV resistance, and provides a tough and durable finish.
