DOWSIL™ 2634 Coating

New alkoxysilane functional perfluoropolyether (PFPE) hybrid polymers that exhibit the synergistic effects of the oleophobicity and low coefficient of friction of fluoro-polymers and the hydrophobicity and durability of silicone. Improved abrasion and UV durability over current chemical treatments are obtained with the use of a mono-functional terminal alkoxy silane to the PFPE polymer. The alkoxy silane reactive end will covalently bond to the surface via hydrolysis and con-densation reactions, resulting in a structurally ordered chemical modi-fication of the surface. This covalent bond gives the needed durability in applications such as touch-screen displays.
