陶氏DOW有机硅涂料DOWSIL™ 2634 Coating

新的烷氧基硅烷官能的全氟聚醚（PFPE）杂化聚合物，其表现出氟聚合物的疏油性和低摩擦系数的协同效应以及硅氧烷的耐水性和耐久性。通过使用单官能末端烷氧基硅烷到PFPE聚合物，获得了相对于当前化学处理的改善的耐磨性和UV耐久性。烷氧基硅烷反应性末端将通过水解和缩合反应共价键合到表面，导致表面的结构上有序的化学改性。这种共价键在触摸屏显示器等应用中提供了所需的耐久性。

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 hydro¬pho¬bi¬city and durability of silicone. Improved abrasion and UV durability over current chemical treatments are obtained with the use of a mono¬func-tional 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.
