PROCESS FOR INCREASING THE PROPORTION OF COMPONENTS WHICH ARE NON-VOLATILE IN PROCESSING CONDITIONS IN BASIC COATING COMPOSITIONS CONTAINING ESSENTIALLY ORGANIC SOLVENTS

摘要

Process for increasing the proportion of constituents, nonvolatile under processing conditions, in base coating compositions containing mainly diluents or organic solvents for the production of multilayer coatings, preferably metallic paints. The process is characterized in that up to 10% by weight of the volatile constituents is replaced under treatment conditions with an aliphatic polyether or mixtures of aliphatic polyethers. Aliphatic polyethers have an average molecular weight of at least 300, contain at least one hydroxyl group per molecule, and must be liquid under normal conditions.
