PURPOSE: Provided is an aqueous dedusting composition for vehicle, which shows excellent dedusting ability when the composition is sprayed on the vehicle and heated and cured, and gives lightening effect on vehicle. CONSTITUTION: The aqueous dedusting agent composition comprises; 20-30wt.% of an acryl resin emulsion having a glass transition temperature of 10-50deg.C, an average particle size of 0.05-0.3 micrometer, and a weight average molecular weight of 100,000-600,000g/mol; 5-15wt.% of alkyd, urethane, or an epoxy-modified acryl resin having a glass transition temperature of 10-40deg.C and a weight average molecular weight of 150,000-500,000g/mol; 2-3wt.% of a curing agent such as melamine-based compounds; 40-60wt.% of an inorganic fine particle filler selected from the group consisting of calcium carbonate, clay, barium sulfate, talc, mica, kaolin, diatomite, and bentonite; 3-5wt.% of a hollow ceramic filler having an average particle size of 50-300 micrometer and a specific gravity of 0.4-0.7. |
