Polyurethane (PUR) in its standard version is ether-based, but we also offer an ester-based alternative. Ether-based PURs are hydrolysis-resistant and stable for outdoor use with good aging properties. Polyester types possess good chemical resistance with less swelling and increased resistance to abrasion. Normally the color is yellowish brown but it can vary greatly. The coloring possibilities are great.
PUR is available in hardness from 50 Shore A up to 99 Shore A as standard. It’s also available in hardness according to the Shore D scale.
