Abstract: A METHOD FOR DRY ELECTROSTATIC COATING OF BASE METAL SURFACES TO PROVIDE CONTINUOUS, EVEN, RESIN FILMS FREE OF PIN-HOLES AND CISSINGS WITHOUT THE NECESSITY OF PRE-HEATING THE BASE METAL BY COATING THE SURFACE OF THE BASE METAL WITH A PRIMER COMPRISING A VEHICLE AND AN ELECTROCONDUCTIVE PARTICULATE MATERIAL HAVING A PARTICLE SIZE OF NOT MORE THAN 100U, SUCH AS ALUMINUM POWDER, IN AN AMOUNT NECESSARY TO PRODUCE A DRY FILM HAVING A VOLUME RESISTIVITY OF 10**9 TO 10**14 OHM-CM., AND DRYING THE FILM.

Abstract: A METHOD FOR COATING THE INNER SURFACE OF A METAL PIPE HAVING AN INNER DIAMETER OF 2 TO 15CM. IS CHARACTERIZED BY HEATING SAID METAL PIPE ELECTRICALLY GROUNDED AT A TEMPERATURE OF FROM A SOFTENING POINT OF A COATING COMPOSITION TO BELOW A MELTING POINT THEREOF, FEEDING NEGATIVE CHARGED DRY PARTICLE OF A COATING COMPOSITION INTO THE INTERIOR OF SAI METAL PIPE FROM ONE END OF THE PIPE AND SUCKING AIR AT THE SAME TIME FROM THE OTHER END OF THE METAL PIPE SO AS TO FORM AN AIR STREAM CARRYING THE PARTICLES AND TO ALLOW THE PATICLES TO DEPOSIT ELECTROSTATICALLY ON THE INNER SURFACE OF THE PIPE.

Abstract: WHEN A COPOLYMER OF AN AVERAGE POLYMERIZATION DEGREE OF 400-700, OBTAINED BY EMULSION-POLYMERIZING 95.099.5% BY WEIGHT OF VINYL CHLORIDE (OR A MONOMER MIXTURE OF MORE THAN 80% VINYL CHLORIDE AND ANOTHER ETHYLENIC MONOMER COPOLYMERIZABLE WITH VINYL CHLORIDE) AND 0.5-5.0 WEIGHT PERCENT OF AN UNSATURATED GLYCIDYL COMPOUND, IS HEATED TOGETHER WITH A PLASTICIZER AND STABILIZER SO THAT THE LATTER ARE ABSORBED IN THE RESIN PARTICLES, THERE IS OBTAINED TO POWDERY RESINOUS COMPOSITION WHICH SHOWS EXCELLENT ADHESION AND FILM FORMING PROPERTIES EVEN WHEN DIRECTLY APPLIED TO A SUBSTRATE, PARTICULARLY METAL SURFACE WITHOUT PREAPPLICATION OF A PRIMER.
