Multifunctional Systems for Wood Preservation Based on Solvents Derived from Renewable Resources Resulting in Water Repellent Wood

Objective



There is a pronounced industrial need today to replace light organic solvent preservatives, LOSPs, (which generally contain aromatics) with a more environmentally acceptable system having equal or improved performance in wood treatment. This would increase the competitiveness of wood with respect to PVC and aluminium as a construction material.
This project will develop wood preservation systems using solvents produced from renewable resources. The solvent systems developed will simultaneously work as carriers for wood preserving additives and give a water repellence of the impregnated wood. It is expected that these new systems will immobilise the biocide once inside the wood. They will also penetrate into the more polar and water sensitive parts of the wood enabling a more efficient action of the biocide. They will in themselves act as a biocide, hence, decrease the need of biocide. The developed systems are expected to be better than existing systems with respect to

wood preservation,
water repellence
environmental impact.

The project is aimed at the joinery market since the technical requirements for joineries are very stringent providing specific test methods including dimensional stability. Furthermore, systems suitable for preservation of joineries can be used in other less demanding applications, where for example dimensional stability is not a requirement. Additionally these systems can be further developed for use in tougher environments. The project is very focused, but has many potential spin offs, both in the wood treatment area, as well as in other areas, such as in plant protection.

The consortium comprises two manufacturers of solvents from renewable resources, two manufacturers of biocides, one formulating company and one wood company. Three research laboratories, complement the industries with their expertise in technology. Their expertise is in the fields of surface and colloid chemistry and wood preservation technology and testing.
