Abstract

Multi-cpoxy functional - glycidyl ether is used as a cross-linking epoxy compound between modified 22'44'-tetrahydroxybenzophenone and silicone molecules. The adduct reaction products, as effective abrasion resistant coatings and yet reactive in the sol gel process, are formulated into the colloidal based polysiloxane resin as an essential part of the solution for dip coating sheets. Such coatings incorporate ultraviolet radiation selection or absorbing compounds with superb chemical stability and mechanical strength for coatings on substrates such as glass. The hardness of these coatings was measured at 6H following ASTM (D-3363) film hardness by pencil test. The resulting coatings were exposed to ultraviolet (UV-A) radiation during a time greater than 600 hours. The exposed samples still maintain excellent absorption in the UV range.
