Summary
A method of treating timber before applying a coating has been developed and tested. An organofunctional silane coupling compound was found that was capable of reacting and forming bonds with both wood and a range of coatings. Wet and dry adhesion strength between a range of coatings and wood has been determined by the direct pull-off test under a variety of test conditions. The data presented show how the bridging of the interface between wood and coating can, with some coatings, improve not only the initial bond strength but also provide significantly higher wet adhesion strength and long-term bond durability.
