Trapylen® 113 S is a chemically modified low-chlorinated polypropylene known for its exceptional affinity to polyolefinic plastics, including PP, PP/EPDM-blends, and, with certain limitations in adhesion strength, PE. Notably, it possesses a higher molecular weight and a narrow molecular weight distribution compared to other modified chlorinated types. Due to its reduced content of maleic anhydride, this product exhibits good compatibility properties with other binder resins. Trapylen® 113 S finds versatile applications, serving either as a straight primer or as an adhesion promoter for base coats and pigmented primers. Its primary use is in paintings and coatings for molded parts, including sealing profiles in the automotive industry, such as bumpers, side panels, and door seals.
