ABSTRACT:
A novel primer composition containing a partial hydrolyzate of an aminoalkyl-substituted trialkoxysilane, a carboxylic acid salt of tin and a solvent is applied to a moisture-cured silicone substrate and dried to improve the adhesion of a subsequently applied coating. The composition and method are of particular value for painting a moisture-cured silicone substrate disposed on a support, such as a building sealant used on a window assembly or an encapsulant used on an electrical device.
