3. Polyaspartic Introduction
Aspartic ester is a new type of aliphatic series, slow reaction, high property, environmentally friendly coating material called the third generation Polyurea.
Polyaspartic Polyurea was first applied by Bayer in 1990 as a polyurethane coating reactive diluent to lower the VOC. It is mainly used in heavy-duty, waterproof, wear-resisting floors and other high-end fields.
