Wood protective coatings based on fluorocarbosilane

Abstract

Abstract The effectiveness of protective coatings based on 3-(2,2,3,3,4,4,5,5-octafluoropentyloxy)propyltriethoxysilane in the protection of wood surface from the effects of water was tested. No earlier attempts at using the mentioned fluorocarbosilane for the protection of wood have been reported in the literature. The coatings were deposited by the sol–gel method. As a result of the generation of chemical bonds between the wood surface and silane, a coating was produced that permanently increased the wood hydrophobicity. Fluorinated chains attached to the silicon atoms make an effective barrier preventing the access of water and limiting the effects of water on the wood surface.
