Abstract: The present invention relates to a method of strengthening brittle oxide pieces such as glass pieces with a siloxane-acrylate coating system that has superior weatherability, particularly hydrolytic stability. The coating system comprises a combination of a silane solution and a radiation-curable acrylate solution. The mixture is applied to a clean, brittle oxide surface. The silane solution comprises one or more silanes in a non-aqueous solvent and the radiation-curable acrylate solution comprises one or more acrylate or methacrylate monomers, acrylate or methacrylate oligomers, and initiators, such as photoinitiators.

Abstract: A glass fiber web and a wet lay process of making the glass fiber web. The glass fibers of the web include glass fibers sized with a sizing composition which includes a partially amidated polyalkylene imine cationic lubricant randomly dispersed in a cured thermosetting resin. The wet lay process includes the steps of so sizing the glass fibers followed by separating such fibers by immersing the glass fibers in an aqueous dispersant medium to form an aqueous dispersion which is agitated. The separated sized glass fibers are dried. The dried, sized glass fibers are then bound with the thermosetting resin binder. The curing of the binder produces the product glass fiber web.
