Surface treatment composition for glass fibers, method of coating glass fibers with said composition, and method of preparing glass fiber reinforced polyepoxide products

摘要

The invention is directed to a surface treatment composition for glass fibers comprising an aqueous solution or emulsion of an organosilane which contains at least one isoimido group. The organosilane with the highest adhesion promotion is N-2-(isomaleimido)-aminoethyl-3-aminopropyl-trimethoxysilane. The invention also comprises a method of coating glass fibers with said silanes in an amount of at least about 0.2 % b. w. of said aqueous solution. Furthermore, the invention comprises a method of preparing glass fiber reinforced polyepoxide products.
