Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a water-based siloxane coating composition for wood materials and wood-based materials, which contains substantially no alcohol and is excellent in the permeability into wood materials and wood-based materials and the protection properties for wood materials and wood-based materials, can provide excellent textures of wood materials, and has excellent storage stability; and a use of the water-based siloxane coating composition. The problem can be solved by a coating composition for wood materials and wood-based materials, which comprises (a) a water-based siloxane compound having an amino group, (b) a water-based compound having an epoxy group or a polyol group, and a water-based solvent, in which the ratio of the mass A of the component (a) to the mass B of the component (b), i.e., A/B, is 0.08 to 14, the composition contains no alcohol or contains an alcohol at a content of 5% by mass or less, and the pH value of the composition is 7 or more.
