Chemical and biological studies of organotin treated and painted wood stakes after outdoor exposure
M-L Edlund, B Henningsson
Organotin based wood preservatives containing tributyltin oxide (TBTO) or tributyltin naphthenate (TBTN) are used in Sweden mainly for double-vacuum treatments of window joinery of Pinus sylvestris. After impregnation the joinery is painted or stained in different colours. To evaluate this effect (different colours on the degree of degradation of TBTO and TBTN, effected by different temperatures in the wood), stakes of Pinus sylvestris sapwood were treated with TBTO or TBTN, painted in different colours and exposed outdoors out of ground contact.
