Surfacer treating process for blemished electrocoat substrates

Abstract

Abstract THIS PATENT APPLICATION SETS FORTH A PROCESS FOR SURFACE TREATING AN ELECTRODE SUBSTRATE USED IN ELECTROCOATING, SPECIFICALLY, ONE WHICH HAS SURFACE IMPERFECTIONS OR BLEMISHES, AND A SURFACER COMPOSITION THEREFOR. THE SURFACER COMPOSITION IS A CURABLE MIXTURE COMPRISING BINDER RESIN AND SUFFICIENT ELECTRICALLY CONDUCTIVE FILLER MIXED THEREWITH FOR AT MOST INSIGNIFICANTLY CHANGING, IN CURED THIN FINAL SECTION ON A BLEMISHED SURFACE REGION OF SAID SUBSTRATE, THE ELECTRICAL RESISTANCE OF SAID REGION RELATIVE TO THAT OF THE UNTREATED ADJACENT SUBSTRATE TO BE COATED. IN ACCORDANCE WITH THE PROCESS SURFACER COMPOSITION IS APPLIED IN THIN LAYER TO THE BLEMISHED REGION OF THE SUBSTRATE, CURED (AND WHEN APPROPRIATE FURTHER AND FINALLY FINISHED AS BY WET SANDING), THEN THE THUS-TREATED SUBSTRATE IS ELECTROCOATED WITH PAINT.
