Preparation, Surface Characterization, and Water Resistance of Silicate and Sol-Silicate Inorganic-Organic Hybrid Dispersion Coatings for Wood.

ABSTRACT: The purpose of this study was to comparatively investigate the behavior of silicate and sol-silicate coatings non-modified or modified with an organosilane on wood and on wood pre-coated with silica-mineralized primers. Adhesion strength, morphology, and water permeability and related damages were studied to evaluate the possibility of utilizing such inorganic-based coating systems for durable protection of wood without or with relatively cheap and water-borne primers. Potassium silicate and potassium methylsiliconate aqueous solutions and a colloidal silica were used for the preparation of the coatings. The white coating paints were brushed on beech wood substrates at a rate of 220 g·m-2. The coatings exhibited good coverage ability. The pull-off adhesion strength values appeared to be re
