Trapylen® 137 S is a chemically modified low-chlorinated polypropylene renowned for its exceptional affinity to polyolefinic plastics like PP, PP/EPDM blends, and, to a certain extent, PE. It serves a dual purpose as both a straight primer and an adhesion promoter, proving valuable for base coats and pigmented primers. Its primary application lies in the realm of paintings and coatings for molded components and sealing profiles within the automotive sector, spanning areas like bumpers, side panels, and door seals. Additionally, Trapylen® finds utility in adhesives and flocking agents for door seals, as well as in various industrial applications where chemically pretreated PP-based plastics are employed.
