WATER REPELLANT SURFACE TREATMENT FOR AIRCRAFT TRANSPARENCIES AND METHODS OF TREATING AIRCRAFT TRANSPARENCIES

摘要

A method of treating an aircraft transparency includes applying a water repellant coating composition over a surface of an aircraft transparency substrate, the water repellant coating composition includes a non-chlorinated perfluoroalkylalkylsilane and/or a non-halogenated polyorganosiloxane. The method can include applying a primer composition having an organic solvent and a silicon material over the aircraft transparency substrate to form a primed substrate surface; applying the water repellant coating composition over the primed substrate surface; and heating the water repellant coating composition to form a water repellant coating.
