AgeSin® AP-G3740P is a modified chlorinated polypropylene-based adhesion promoter. 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.
AgeSin® AP-G3740P
High-Performance Adhesion Promoter for Polyolefin Substrates
AgeSin® AP-G3740P is a modified chlorinated polypropylene-based adhesion promoter specifically engineered to overcome the challenge of poor paint adhesion on polyolefin surfaces, such as polypropylene (PP) and polyethylene (PE). Unlike conventional chlorinated polyolefins, AP-G3740P incorporates reactive functional groups within its molecular structure. This innovative design enables it to form strong chemical bonds with polyurethane and other coating systems, creating a durable anchor that significantly improves coating adhesion and long-term performance.
