CCFZ, a new type of water-borne wood preservative for vacuum pressure impregnation

IRG/WP 3643

W Metzner, D Seepe, H-W Wegen

By combination of CCF-Salt types with zinchexafluorosilicate a remarkable improvement of efficacy is achieved. In the same time the ecotoxicoligical data become more save. As well as the efficacy against wood-destroying organisms (Basidiomycetes, Soft rot and Long horn beetle) the basic data to evaluate the ecotoxicological behaviour of a CCFZ-Salt are described and compared with the properties of a well known CCF-Salt. The deminished input of heavy metals per m³ of impregnated wood represents a contribution to decrease the environmental pollution.
