CH-920 aromatic water-borne polyurethane resin is much suitable for rigid substrate coating, like wood, plastics, concrete, metal, etc. CH-920 can be used alone, also can be mixed with other acrylate emulsion. CH-920 paint film have excellent hardness, tensile resistance, flexibility, chemical resistance and high gloss.
