Water Proof agent BRSS-702A
1. Characteristics
Water proof agent BRSS-702A is a kind of styrene-acrylic copolymer emulsion without . It has no chlorine content (the content of 1,3-dichloro-2-propanol and 3-chloro-1,2-propanediol is less than 5ppm). It has cationic nanometer-size particles, good chemical stability and good retention in pulp. It can offer excellent water resistance for pulp molding paper and paperboard products of food contact packaging.
