光沢を低下させる。The emulsifying polyethylene wax is a dispersion colloid having coarse particles, has a strong cohesive force, and is unstable in behavior at high temperatures. When a non-aqueous paint containing emulsifying polyethylene wax is applied to the body of an automobile, the particles of the emulsifying polyethylene wax are coarse and the precipitation of pearl mica is not completely prevented, resulting in a color difference on the painted surface. is there. Further, the cohesive strength of the emulsifying polyethylene wax causes the surface to be rough, and the unstable behavior at high temperatures causes seeding, which reduces the gloss of the surface after baking and curing the coating.
