  • METHOD OF FORMING A COATING FILM
    Publication number: 20100203259
    Abstract: A method for forming a coating film able to reduce curing time, reduce the size of coating equipment and reduce the amount of CO2, without deterioration in such properties as water resistance and weather resistance. The method for forming the coating film includes the steps of (1) applying a base coating composition, (2) applying a top coating composition on the base coat layer obtained in said step (1), (3) irradiating energy line on the uncured coating film obtained in step (2), and (4) bake curing after step (3). The top coating composition includes a hydroxyl group-containing resin (A), an activation energy line-curable compound containing an unsaturated bond (B), and a polyisocyanate compound (c), with a compounding proportion of (A), (B) and (C) based on weight satisfying the ratio: ((A)+(C))/(B)=90/10 to 50/50.
