PURPOSE: A polyurea paint composition is provided to have excellent corrosion resistance, rust resistance, chemical resistance, drug resistance, and workability without using special equipment. CONSTITUTION: A polyurea paint composition consists of a base part, and a hardener part. The base part consists of an epoxy prepolymer, an amine-functionalized resin, a crosslinking agent, an inorganic filler, pigment, and additives. The hardener part is formed by mixing 50-150 parts by weight of one or more selected from polypropyleneglycol, and polyoxypropylene diamine into 100.0 parts by weight of an isocyanate mixture. The isocyanate mixture is one or more kinds selected from hexamethylene diisocyanate, hexamethylene diisocyanate trimer, isophorone diisocyanate, cyclohexylmethane diisocyanate, methylene diphenyl diisocyanate, and toluene diisocyanate.
