Laboratory tests on the residual effects of pyrethroids against termites after one year
1983 - IRG/WP 1216
Due to recent restrictions of ecological nature which most of pesticides are been submitted, it is necessary in wood preservation to test new products and formulation with low mamalian toxicity for substitution of the traditional products. The efficiency of five synthetic pyrethroids in comparison to the traditional organo-chlorinated pesticide chlordane was evaluated. Wood blocks impregnated with...

Pretreatments of wood surfaces for improving weatherability of clear finishing
2001 - IRG/WP 01-40196
The clear film durability of wood is generally very short because of photo degradation of wood surfaces caused by UV through to the film. Pre-treatment of wood surfaces for protecting against photodegradation is very important for clear finishing system. In this study, some pre-treatments, ie; polyethylene glycol (PEG) and UVA grafting (2-hydroxy-4(2,3-epoxypropoxy) benzophenone (HEPBP)), were app...
