ABSTRACT OF THE DISCLOSURE This invention relates to a non-aqueous coating composition and a method for reducing the drying time of a non-aqueous coating composition by incorporating composite polymer particles having a softer, insoluble first stage and a hard second stage without adversely affecting the viscosity and pot life of the liquid coating composition and without degrading the properties of the final dry coating, including color, flexibility, impact resistance, gasoline resistance, salt spray resistance and humidity resistance. The method enables resin manufacturers and coating formulators to reduce the volatile organic content (VOC) of their products without increasing the drying time for the coatings and without adversely affecting the viscosity and pot life of the liquid coating composition and without degrading the properties of the final dry coating, including color, flexibility, impact resistance, gasoline resistance, salt spray resistance and humidity resistance.
