Primer E 500 was developed specifically for the applications with the various Weicon silicones. It improves the already good bonding results, of the elastic sealants and adhesives on most surfaces. Certain bondings on very specific surfaces can only achieve good results by using an appropriate primer.
Primer E 500 is used for pre-treatment of non-absorbent metal surfaces such as aluminum, steel, stainless steel, brass, copper, zinc, and tinplate and other surfaces, such as plastics, enamel, ceramic or glass.
