A kind of high performance two-package automotive refinish was obtained with polyester resin modified acrylic-polyurethanes. The effect of acrylic resins, polyester resins and its amount, curing agent，the ratio of –NCO/-OH, leveling agents, anti-settling agent on film properties was studied. The results showed that the film had the best performance when the mass ratio of acrylic and polyester resin modified by CARDURA E10 (versatate glycidyl) was 5:1 ~ 3:1, N3390 was used as curing agent and the molar ratio of NCO/-OH was 1.08 ~1.15, the ratio of acrylic leveling agent and silicone leveling agent was 10:3, the quality percentage of anti-settling agent was 0.54%.
