Difference Between Epoxy And Polyurethane Resin

Similarities 

Epoxy and polyurethane are great for protecting your surface against stains, damage, chemicals, oils, and wear. They are both light reflective, easy to clean, and long lasting.

 

Differences

Polyurethane is a thermosetting polymer as well and is considered a high-performance coating.  It is commonly known as urethane for short, though that it is technically incorrect and there is a big difference between polyurethane and urethane. If someone is advertising a urethane coating, it is actually polyurethane.

Of the different formulations available aliphatic polyurethane is the desired choice for garage floors.  Though they are approximately 60% to 70% solids depending on the manufacturer, a polyurethane coating is only about 2 to 3 mils in thickness and can’t be adjusted as with epoxy.Don’t let the thinner dry film thickness fool you however. Aliphatic polyurethane has more flexibility than epoxy and it is this flexibility that aids in absorbing impacts better.  It is also much more abrasion resistant.  The wear resistance of

polyurethane over epoxy is almost 3 to 1.  The resistance to chemicals is better than epoxy as well and this includes resistance to solvents such as methylene chloride which is the primary ingredient in paint stripper.

Another advantage of polyurethane over epoxy is that it is U.V. stable.  This means that it won’t yellow like epoxy does when exposed to sunlight over a period of time. Polyurethane can tolerate larger temperature swings and handles humidity much better.

 

Summary

Porous paving allows rain and irrigation water to penetrate the surface, instead of running off like it would from concrete, to conserve water for lawns and gardens. Commercial settings save money with reduced landscaping maintenance and lower irrigation bills. Our unique polyurethane resin binds natural stone, available in 24 natural colours, and recycled glass, available in 6 bright colours, into hardened surfaces that allow water to permeate to prevent erosion and to conserve water to nourish lawns and gardens, and it is the preferred alternative to concrete. We provide Porous Paving Solutions and flexible surfaces guaranteed for ten years, designed to last for 25 years, require little maintenance, and they won’t crack and crumble like concrete.
