Patent number: 11981047Abstract: Method of treating wood products to improve fire resistance thereof. The method comprises treating wet wood objects with compositions comprising an aqueous solution of bisphosphonate selected from 1-hydroxyethane 1,1-diphosphonic acid, an alkanol amine, and optionally an alkaline agent, the composition having a pH in the range of 4.0 to 7.0 to impregnate the object with the compositions, and subjecting the object so obtained to drying to achieve aspiration of the pits of the wood object. The method can be used for protecting wood not only against fire but also against mould, rot, blue stain, insect such as termite attacks on wood, dimensional changes, or a combination thereof due to environmental influence.Type: GrantFiled: September 10, 2019Date of Patent: May 14, 2024Assignee: Palonot OyInventors: Jari Kukkonen, Timo Nissinen
