Hydrophobic treatment for improvement of wood surface durability
Several surface treatments for transparent protection of exterior wood have been tested in natural and artificial weathering by measurements of contact angle, liquid water and vapour absorption, colour change and mechanical properties (« ; thin strip» ; method). Spruce wood was impregnated with HALS-containing primer and subsequently treated with UV-modified, nano-scaled hydrophobic emulsion, or by application of several transparent coatings. Hydrophobic properties (« ; pearling effect» ; and high contact angles) did not correlate well with water absorption, and the weathering resistance depended on the amount of UV additives and film thickness. Providing that sufficient depth of primer penetration and resistance to vapour transport are assured, transparent coating systems containing HALS, UV absorber and nano-based water repellent offer very promising enhancement of exterior wood service life.
