- Abstract
- A wide variety of organo-silicon compounds has been described for application on wood. Some compounds such as organo-functional silanes which are mostly applied in combination with tetraalkoxysilanes (sol-gel process) as well as chlorosilanes and trimethylsilyl derivatives were proposed for a full impregnation treatment of wood. Other systems have been developed for surface treatment of wood such as plasma coating with hexametyldisiloxane and micro-emulsions which mainly contain silane/siloxane mixtures. The effects related to the various treatments vary from an increase in dimensional stability, durability and fire resistance to an enhanced hydrophobation of wood. In the cases of decay and fire resistance a combination of silicon based systems with other chemicals was required to obtain satisfactory results. Due to the excellent water repellent ability and weathering stability of some treatments, application of silicon treated wood under conditions of hazard class III (EN 335 outside above ground exposure) is recommended.
