These finish systems are used in extreme outdoor exposure conditions. 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. 2. Polyurethanes are known for their outstanding UV resistance, gloss retention and color stability. This all depends on the floor application and what the desired end result. They provide a hard finish that is very durable. Another benefit is the use as binder to be mixed with metallic flakes, color quartz, and as a base coat for color flakes. 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. One of the most popular high solids epoxies is Amine Adduct Epoxies. (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. They can be used as a primer, intermediate and topcoat depending on application. The most common type is aliphatic polyurethanes as they are anywhere from 55-75% solids and dry 1-4 mils thick depending on application process. (, Acrylic Polyurethanes are known for their excellent gloss and color retention, UV resistance, and provides a tough and durable finish. Two part epoxy paint is going to be far superior in durability to 1 part paint. With both epoxy and polyurethane floor coating offering a number of benefits, you may be able to combine them to get the best of both worlds. Epoxy and Polyurethane coatings exemplify superior long term qualities such as chemical and acid resistance, ease of maintenance, and aesthetic appeal.

If we have done PU flooring, do we need to add 1 few layers of PU coating on top of the PU flooring? These coatings are made with 100% Polyester resin which provides an extremely durable finish. A. Epoxy paints are two-part paints which, unless mixed, will never cure. Owners at Industrial Facilities often come to us wondering what type of coating system (epoxy vs polyurethante) is needed to protect their assets. Another advantage of polyurethane over epoxy is that it is U.V. Re: 2 Part vs. 1 Part Polyurethane Paint? Powder Coating vs. Epoxy vs. Enamel . Phenalkamines are usually lower viscosity than some of the other epoxies, which makes it a great choice for line stripping in facilities. Whilst a polyurethane system will initially cost more compared to an epoxy, it is far more cost effective in the long term. One great benefit is that these epoxies are usually low VOC and have little to no odor. They’re great choices for internal tank linings, secondary containment, pump pads, trenches, and other high exposure areas. However, polyaspartic aliphatic polyurethane is different. Polyester epoxies are a very unique, two component non-yellowing epoxy coating. 2 Comments. If an uncured PU floor is attacked by water or condensation you may get this catastrophic results (like in the picture below). One of downsides of epoxies is that will eventually chalk and fade. Concrete Floor Paint vs Epoxy Coating. (PC-517, PC-555, PC-590, PC-1500, PC-1875), – Water Based Epoxies: Water Based Epoxies are great choices in less demanding areas. Epoxy Central sells both epoxies and polyurethanes as well as epoxy and polyurethane coating kit. These coatings are used for exterior steel surfaces for long term protection. This includes resistance to petroleum products and solvents, such as methylene chloride, which is the primary ingredient in paint stripper. Owners at Industrial Facilities often come to us wondering what type of coating system (epoxy vs polyurethante) is needed to protect their assets. (, Both of these epoxies are very high performing epoxies that are ideal for harsh chemicals. 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. This means there little to no VOCs in the epoxy as this will give you the strongest coating when applied. Unfortunately, it is this same impressive durability that makes it difficult to paint over epoxy … Bond Polychem, Ahmedabad, Gujarat. This is where Polyurethanes comes in to play, which we will discuss later. (. Some people interchange the terms epoxy coatings and epoxy paints, but the two are quite different.

When it comes to weighting up the benefits of polyurethane vs epoxy floor coating, as the famous taco ad says – “why not both”? These epoxies are designed by having the curing agent with a small amount of epoxy resin. Polyurethanes do not bond well to concrete and do not exemplify the self leveling properties that epoxies do when applied to on these surfaces. Polyurethane originally was an oil-based varnish with more plasticity than older varnishes or paints. Epoxy Coatings vs. Polyurethane Coatings: Which One Should you Choose? These coatings can normally handle higher dry service temperatures than epoxies and two component urethanes. These coatings are usually sold as finish and are usually applied at 2-3 mils DFT. (PC-270). As a rule of thumb, it is best to apply these coatings between 10 AM – 4 PM, which is when the humidity is generally at its lowest point of the day. Website by Dreamedia. 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. They generally have very good chemical resistance which allows the higher performing epoxies to be used for tank linings, containment areas, and for general protection against chemicals. Five Key Parts of Our Superior Epoxy Kits, The Most Common Misconceptions About Epoxy Coatings, 5 Reasons Why You Should Epoxy Your Basement Floor. They provide a hard, high gloss tile-like finish that has outstanding wash and scrubbability.

Hello, 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. Epoxies can be used in a variety of applications from home garages and basements to airplane hangers and commercial grade food processing plants. Usually these epoxies are economical and are used a primer and finish coat. EPOXY RESIN - LPU - MCU - POLYURETHANE . When used as a topcoat over epoxy, they protect the underlying epoxy from yellowing over time. Epoxy vs. Polyurethane vs. Resin vs. Urethane Cement Flooring. 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.
