Antifungal activities of acetone-soluble Eusideroxylon zwageri and Potoxylon melagangai crude extracts against white rot
2012 - IRG/WP 12-30591
The development of natural wood extracts as a wood preservative is a potentially attractive prospect for the wood preservation industry. This study attempts to evaluate the toxicity of Eusideroxylon zwageri and Potoxylon melagangai extractives as potential wood preservatives. These two species are well-known as among the heaviest and very durable timbers. It has been established that natural durab...

State of progress of utilisation of supramolecular gels for formulations of water-soluble wood preservation salts
2013 - IRG/WP 13-30630
This article is a compilation of the work done so far concerning the utilization of supramolecular hydrogels, built on low-molecular-weight amphiphilic molecules and containing boron salts conferring fungicidal properties. Mixing boron with thermoreversible hydrogels allows the formation of a supra molecular network incorporating boron and important amount of water upon gelification of the solutio...

Release of Copper from Pressure Treated Wood
2016 - IRG/WP 16-20584
Micronized copper based wood preservatives including micronized copper quat (MCQ) and micronized copper azole (MCA) have been introduced commercially to the North American market since 2006 as alternatives to alkaline copper quat (ACQ) or soluble copper azole (CA) preservatives. Unlike ACQ or CA, MCQ and MCA use dispersed particulate copper particles rather than soluble ionic copper to make treat...
