Polyurea Chemical Single Component Polyurea Material
Description of Single Component Polyurea
Polyurea is an ideal product for many containment applications. It
can be applied to virtually any surface. Concrete, steel,
aluminium, wood and foam are a few examples of the types of
surfaces that can be coated.
Features of Single Component Polyurea
Polyurea offers high abrasion resistance, high chemical resistance,
excellent durability, and excellent flexibility and is inert (won't
leech anything into containment area).
