Which is better epoxy or polyurethane? Polyurethane Coatings Though they exhibit much thinner cured-film thickness, polyurethanes offer a number of unique advantages over epoxies. Increased Impact and Abrasion Resistance: Polyurethanes exhibit excellent impact and abrasion resistance, providing up to four times longer life than uncoated epoxy floors.
Can you use polyurethane like epoxy?
In the long run, while polyurethane is water-resistant, it's not as good at warding off the water as epoxy resin is and if your finished product is likely to spend a lot of time getting wet – you might want to avoid polyurethane.
Which is harder polyurethane or epoxy?
Generally, a polyurethane floor coating is highly flexible and elastic, while epoxy flooring is harder and more brittle. This makes polyurethane coatings more resistant to scratches and similar damage and is why you'll often find urethane resin floors in heavy traffic areas – such as multi-storey car parks.
Is polyurethane good for countertops?
Polyurethane is a durable, resilient varnish that seals and coats wood with a cover that resembles plastic. It is excellent for use as a finish on cabinets and countertops, especially since it is not affected by acidic foods, beverages and cleaning substances.
