Modification of wood by graft treatment
2003 - IRG/WP 03-40257
New water-repellent systems for wood are needed to improve the weathering characteristics. This study found that treatment of wood with chemical grafting systems imparted substantial water repellency. Different direct oxidative grafting systems were examined. Specifically, KMnO4, Fe(NH4)(SO4)2·12H2O, Fe2(SO4)3·5H2O, and (NH4)2Ce(NO3)6 were used as initiators and styrene as the monomer. All the...

Environmentally benign wood preservatives based on organic biocide antioxidant combinations: A brief review of laboratory and field exposure results and discussion of a proposed mechanism
2004 - IRG/WP 04-30335
The combination of various organic biocides with commercial antioxidants generally increased the biocides’ efficacy 2-3 fold against wood-destroying fungi in short-term laboratory decay tests, and some positive results have been obtained after 2-4 years of outdoor exposure. The two antioxidants principally examined, propyl gallate and butylated hydroxytoluene, are low cost and, since both are f...
