Polyurethanes provide the enhanced performance characteristics that protect the entire system.
Whats the difference between polyurethane and epoxy?
In general Epoxy floor coating are tougher. They have higher durability and higher compressive strength as compared to polyurethane flooring. Polyurethane floor coatings, on the other hand, are typically “softer”. They are more flexible and therefore more scratch resistant.
