The development of a new boron-based wood preservative

P Turner, D Conradie
The paper describes a new boron based wood preservative for the treatment of green timber. The product offers many benefits over conventional boron diffusion treatment including: 1. high viscosity, high concentration formulation; 2. permits dip treatment of a wide range of sawn board and pole sizes at ambient temperatures; 3. permits full cross section diffusion of borates without block stacking and wrapping of treated material; 4. treated material is ready for use within a few hours after dipping, this eliminates long storage periods; 5. a water-repellent coating which acts both as a leach retardant and protects the timber against weathering; 6. the new product permits the use of borates in H3 class situations. Evaluation of diffusion trials and simulated rain test data on treated material is discussed.
