ABSTRACT: Three major types of
protective coating of wood and wood-based materials have been considered. These
three types include the coatings based on carboxyl-containing water-soluble
polymers which are easily cross-linked by inorganic salts or OH-containing
compounds, pH-sensitive coatings and polymer multi-layer structures. First of
three mentioned approaches allows affecting permeability and enhancing the
prevention the loss of water from the surface of wood to its surrounding. The
advantage of the second approach is its ability to vary and purposely adjust
the polymer composition and the number and distribution of -COOH groups in the
chain which make the originally water-soluble polymers completely insoluble.
The strong feature of the third approach which includes broad use of
hydrogen-bonded films produced by layer-by-layer self-assembly is the
possibility of manipulation of coatings stability after construction.
