Procedure

A mixture of 9.94 g of 3-aminopropyltrimethoxysilane and 15.4 g of hexanedioldiacrylate is stirred at room temperature for 3 hours. To the mixture, 28.5 g of PM glycol ether is added. The resulting mixture is stirred at room temperature for 1 minute. Then, 1.73 g of acrylic acid is added, and the mixture is stirred for 5 minutes. The mixture is diluted by adding 106.7 g of isopropanol. Next, 84.4 g of OG401-31 and 34.7 g of NALCO 1034A are added under vigorous agitation. The resulting mixture is stirred at room temperature for 1 hour. 0.74 g of a solution of EBECRYL 1360 (50% by weight in PM glycol ether), 3.98 g of DAROCUR 1173, and 64.8 g of n-butyl acetate are added. The resulting coating composition is stirred for an additional 30 minutes to ensure mixing.
