Introduction:

KH-151 silane, vinyltriethoxysiane, 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.
