WATER-EFFECTIVE STORAGE AND COMPENSATION SLACK, THEIR USE AND PROCEDURE FOR THEIR PRODUCTION

摘要

A water-dilutable stone impact protection paint (I) contains (A) 20-60 wt.% binder and (B) 2-10 wt.% pigments. Also claimed is a water-dilutable compensation paint (II) contg. 40-80 wt.% binder (A). Also claimed is a process for the prodn. of paint (I) which can be dried at 50-90 degrees C, by taking uncoagulated overspray (III) from spray booth effluent contg. water-soluble base paints, concentrating to 10-35 wt. % solids by removing water and mixing with the components required for stone impact resistant properties. Also claimed is a process for protecting car bodywork with an electrophoretic primer, a layer of (I) 10-20 mu m thick instead of the usual filler coat, a layer of water-soluble base coat, and a clear topcoat, in which (I) is dried at 50-90 degrees C, the base coat is dried at 50-100 degrees C, and the entire system is then stoved at 130-160 degrees C.
