Abstract
Abstract Organosilicone compositions which consist essentially of the product of the reaction of a mixture of a certain aminoalkylalkoxysilane and a certain epoxyalkylalkoxysilane. The organosilicone compositions are used in the form of a blend with a sealant or a primer coating for improving the adhesion of such blends onto various surfaces, or the adhesion of the sealant itself onto the various surfaces, respectively.
