Adhesion to Arkema's Kynar® Resin-Based Coatings

Arkema introduced Kynar 500® PVDF resin in 1965. For over 50 years, Kynar 500® resin- based coatings have been the industry standard, providing protection and preservation to aluminum, galvanized steel and aluminized steel. With extreme weatherability, excellent dirt shedding and mildew resistance, they make metal functional and eye-pleasing, adding a unique finish that resists chalking, pitting, chipping or premature aging.

However, these coatings are slick, which traditionally has made adhering to their surfaces difficult.

Bostik has solved this problem by developing a full line of high-performance sealants and adhesives that have unprimed adhesion to Kynar resin-based coatings. These smart solutions provide a watertight bond to a variety of applications and improve systems as a whole.


Bostik, Inc. is the only recommended supplier of sealants and adhesives for Kynar 500® resin-based painted surfaces.
