TRAPYLEN® 9500 W primer for sealing applications

TRAPYLEN^® 9500 W is a chlorine-free, waterborne adhesion promoter based on acrylate-modified polypropylene. Featuring a high melting point of 120 °C, TRAPYLEN^® 9500 W provides excellent temperature resistance and flexibility. These properties make it ideal for use in processes that are performed at high temperatures, for example heat-sealing aluminum to polypropylene.

In addition, due to the nature of the process, TRAPYLEN^® 9500 W is solvent-free, which both reduces the environmental impact and increases occupational safety as no harmful vapors are released.

A further product highlight is its exceptional affinity with polyolefin films, especially those based on PP, TPO and TPE. As a result, it is particularly suitable for the chemical pre-treatment of these films and of molded parts made of polypropylene and PP blends that are to be subsequently coated or embossed. TRAPYLEN^® 9500 W can also be incorporated directly into dispersions of adhesives, lacquers or printing inks if compatible.
