Adhesion improving and crack phenomenon lowering method, involves treating surface of converter housing to be coated with isolation lacquer with solvent-containing cleaning liquid before applying isolation lacquer

摘要

The method involves treating a surface of a converter housing to be coated with an isolation lacquer with a solvent-containing cleaning liquid before applying the isolation lacquer, where an adhesive layer is applied on the surface of the converter housing. A wash-primer is utilized as the adhesive layer, and a flexible extension layer is applied after coating with the isolation lacquer.
