TOPCOATING METHOD FOR AUTOMOBILE

摘要

PURPOSE:To prepare an excellent composite color efficiently by forming a mica base film containing a specific quantity of coating mica with specific diameters and a clear film over the colored intercoating of comparatively high brightness color range by means of two coating one baking. CONSTITUTION:On an electro-deposited film prepared in the automobile manufacturing process, an intercoating film of N1-N6 Munsell value brightness is formed. Over said intercoating film, after its surface is adjusted by wet sanding or the like, a mica base coating containing 1-30wt% of coating mica with 0.1-30mum diameters is coated. An air spraying-type electrostatic coater is used in this case and finished in two stages. By coating and stoving a clear coating as a top layer by means of the wet-on-wet method during said mica base coating is uncured yet, a film of an excellent composite color without coating unevenness is formed.
