Polyurethane Floor Coatings

Polyurethanes are polymers that are connected to a chemical compound group known as carbamates. Polyurethane is a thermosetting polymer by nature so it does not melt when heated. Polyurethane applications may look like epoxy coatings, however they possess distinct characteristics that make them ideal for specific applications.

Unlike epoxy coatings, which are highly stiff and impact resistant, polyurethane floor coatings are relatively softer and more elastic.This attribute makes polyurethane coatings better suited for areas of moderate to heavy pedestrian traffic. The increased elasticity also makes polyurethanes more resistant to abrasion, since impact loads are easily absorbed and less prone to cause scratches.The elasticity and flexibility of polyurethanes also contribute to their ability to operate in environments with low freezing temperatures.

These characteristics make polyurethanes ideal for applications like car parks, freezing chambers and busy commercial facilities such as shopping malls, airports, and hospitals.

Short Curing Time

One of the other significant advantages of polyurethane coated floors is the curing time. Floors coated with this material can be ready for operation the next day. In contrast, epoxy coatings need at least seven days to cure prior to floor use.

While polyurethanes have several advantages...they do have a few shortcomings. Polyurethanes are highly sensitive to moisture. When moisture attacks the floor, bubbles can form on the surface causing unsightly blemishes. Polyurethane is therefore not recommended for use in areas with high levels of humidity. Their limited pot life and moisture sensitivity also make them challenging to work with. A professional Kremer Davis application crew is extremely important.
