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