SICONG® 2-Perfluorooctylethyltrimethoxysilane，The rate of hydrolysis is faster than that of fluorinated silane ethoxy, higher efficiency.in hydrolysis after release of low molecular weight alcohols,the resulting active silicon alkoxide,and many inorganic and organic substrates in hydroxyl,carboxyl and oxygen containing groups chemically bonded,on the surface of minerals formed by self assembly of single molecular fluorine silicon film.The treated substrate with low surface energy and poor wettability ,has excellent hydrophobic,oleophobic and antifouling performance.
