ABSTRACT:
A coating composition adapted for repairing a damaged coating on a substrate comprises as the binder a mixture of a polyacrylate, an acrylated alkyd resin and a cellulose ester which form 100 percent of the binder. The coating composition is particularly well suited for use in preparing damaged paint on a motor vehicle body. The binder may be mixed with a volatile inert organic solvent for the binder in making the composition. The composition has a higher solids content than composition usually used for repairing damaged coatings and much thicker layers of the coating composition may be applied. By mixing the components of the binder in the ratio of 10 to 60 parts by weight of polyacrylate to 30 to 75 parts by weight of acrylated alkyd resin and 5 to 45 parts by weight cellulose ester to form the binder a coating composition having reduced tendency to crack and of improved solids content is obtained.
