Open the CIPO recordAbstract From the Canadian patent
An adhesion promoter for use with an ultraviolet radiation curable siloxane composition is made by combining an alkoxysilicon compound of the formula (RO)3Si-X-Si(OR)3, and a compound capable of catalyzing the reaction between two alkoxy groups or an alkoxy group and a hydroxyl group. Ultraviolet radiation curable siloxane compositions with the improved adhesion are obtained by mixing the adhesion promoter with a mixture which has at least one ultraviolet radiation activatable siloxane polymer and a photoinitiator. These compositions can be used as optical fiber coatings conformal coatings and other coating applications where adhesion to a substrate is important.
