GY-S-6518

Coupling agent in filled polymer systems, which cure via a free radical mechanism.
Finish for glass or a binder additive in glass-reinforced polyester resins.

Description

Intro

GY-S-6518 silane is a vinyl-functional silane that may be used to improve the bond between glass fiber or mineral fillers and resins that are reactive towards the vinyl group. It is also employed to functionalize resins via free radical mechanisms-copolymerization or grafting and to modify surfaces.
