Abstract

Accelerated weathering of wood surfaces coated with hexadecyltrimethoxysilane (HDTMOS) in the presence of methyltrimethoxysilane (MTMOS) by the sol-gel process was investigated. The sol-gel process allowed the deposition of a covalently bound thin layer of polysiloxane networks on the wood surface that was resistant to water sorption and water leaching. The rate of weight loss resulting from surface erosion and the extent of surface color loss caused by photo- nduced discoloration were decreased for coated specimens compared to uncoated specimens.
