CHIPPING RESISTANT PAINT

摘要

A water based chipping resistant paint which contains a solid component (30 to 65 weight percents) and a slowly-evaporating solvent (0.1 to 10 weight percents) as a water based dispersion substance and wherein the solid component contains a resin having a film forming function, thermally expansive fine grains and a chipping resistant material (respectively, 15 to 75 weight percents, 0.2 to 25 weight percents and 20 to 80 weight percents). The chipping resistant paint facilitates vaporization of water at the time of film formation owing to mixing of the slowly-evaporating solvent, can prevent cracking and blistering of a film due to water remaining in the film and vaporization of water remaining after the film formation, and readily form a thick film owing to an expansion effect of the thermally expansive fine grains at the stage of baking after coating, and therefore is suitable for a chipping resistant undercoat for automobiles.
