Title:
MANUFACTURED WOOD PANELS WITH ELEVATED LEVELS OF ZINC BORATE ADDITIVES FOR IMPROVED SURFACE PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2024/010816
Kind Code:
A3
Abstract:
A method or process for a system for applying high, elevated levels of zinc borate additives to composite or manufactured wood panels, such as oriented strand board, for improved surface antifungal and anti-termite properties. Zinc borate is applied to one or more surface layers of a manufactured wood panel at approximately 2.0% (m/m) or higher, more preferably above 2.0% (m/m) to approximately 2.5% (m/m), which produces the surprising result of resisting surface fungal growth. In particular, OSB panels generated from Aspen and Southern Yellow Pine (SYP) wood species are successfully treated with zinc borate levels of at least approximately 2.0% (m/m), and found to resist surface fungal growth.
