The treatment of sawn whitewood with organic solvent wood preservative

IRG/WP 3192

L D A Saunders

The impregnation schedules approved in the UK for the treatment of sawn European whitewood (Picea abies) with organic solvent borne preservatives result in comparitively high loadings relative to the limited depth of penetration they achieve. Results are presented, which show how substantial reduction in the overall loading may be achieved without concomitant reduction in penetration. A model for organic solvent behaviour is postulated as a basis to account for these findings.
