DCOI - An Oil-borne Preservative System for Pressure Treatment of Poles, Posts and Sawn Cross Arms

摘要

DCOI or 4,5-Dichloro-2-octylisothiazol-3(2H)-one is a broad-spectrum antimicrobial compound that was first standardized as a wood preservative by the American Wood Protection Association in 1989. In 2008 DCOI was successfully commercialized in the U.S. residential wood preservative marketplace as a waterborne formulation for above ground uses. In 2017 proposals for an oil-borne formulation of DCOI intended for the pressure treatment of southern pine poles, posts and cross arms as well as Douglas-fircross arms were considered and adopted by the AWPA Technical Committees. Publication of the new/revised standards is expected in the 2018 BOS. This paper summarizes available data associated with the chemistry, the human and ecotoxicological properties,the treatability and the efficacy of the active ingredient in an oil borne formulation that supports its use as an effective wood preservative for industrial applications.
