Aqueous coating composition and its preparation |
摘要 |
An aqueous coating composition wherein fine grains coated with water soluble resin composed of three monomers are contained in aqueous medium, each of said fine grains are composed of aqueous resin of ethylenically unsaturated monomer and aqueous colloidal silica, which are coexistent each other. Therefore, the aqueous coating composition is superior in not only contamination resistance, but also waterproof and weatherproof. The paint film formed by the above aqueous coating composition is excellent in its strength. Accordingly, this aqueous coating composition is useful for a coating base of exterior type coating material.
