Epoxy functional silicone materials incorporating vinyl containing multifunctional resins form control release additives when the resins are first partially crosslinked by means of a hydrosilation reaction with a low molecular weight SiH silicone fluid and the reaction product is reacted with an epoxy containing material in a second hydrosilation reaction. The resulting materials function as control release additives in pressure sensitive adhesives.
