Abstract : Swedlow's abrasion resistant coatings on acrylic windows have now provided up to eight years serviceability against the harsh environments of people abuse and automated cleaning procedures. The superior performance of the Swedlow coatings over that of all other commercially available coatings has been confirmed by many independent facilities. General Motors Corp., for example, has recently approved only two coatings, Swedlow's SS-6590 and SS-6712, for use on the formed acrylic sunroofs for their 1984 Corvette. This represents the first significant entry for plastics into automotive transparencies in this country. In aircraft applications, the SS-6590 and SS-6712 coatings are undergoing extensive laboratory and flight testing. Coated as-cast acrylic windshields have demonstrated excellent abrasion and chemical resistance in non-pressurized general purpose and agricultural spray aircraft. On stretched acrylic material, the coatings conform to CAR 3.27(a) and 3.396(a) pressurization testing and have successfully achieved over 5000 flight hours on cabin windows in a TWA operated 727 aircraft.
