AgeSin® AP-G3740P is a modified 氯化聚丙烯 (CPP)-based 粘接促进剂. Unlike conventional chlorinated polyolefin promoters, AP-G3740P features reactive functional groups along its molecular chain. This unique structure enables it to form strong interactions and anchoring bonds with polyurethane and similar coating systems, significantly improving the adhesion of paint films to polyolefin substrates such as polypropylene.
