    摘要: A coating composition for the protection of metallic substrates against environmental attack comprising, in weight percent, from about 10% to about 30% of at least one film-forming polymer such as epoxy resins having an epoxide value of about 250 to about 2500, vinyl chloride resins copolymerized with polyisocyanates, polyurethane resins, and polyester resins; from about 40% to about 55% particulate metallic zinc; from about 4.75% to about 7% zinc-coated hollow glass-like microspheres having diameters ranging from about 2.5 to about 60 microns, the volumetric ratio of the metallic zinc to the microspheres ranging from about 0.8:1 to 1.2:1; from about 1.5 to about 3% of at least one particle size grade of a pyrogenic amorphous silica having an average particle size ranging from about 0.007 to about 0.04 micron; and not more than 30% solvents compatible with the film-forming polymer. A dried coating of this composition, having a thickness of at least about 4 mils (about 100 microns), is cathodic and electrically non-conductive.

    摘要: Thermally stable hot applied plastisol compositions are especially useful in the assembly of metal parts. The compositions have adhesive and sealant qualities which allow them to be used in automotive assembly plants. Compositions of the invention comprise as major ingredients finely divided polyvinyl chloride resin, plasticizer, thermoplastic polymeric resin which is solid at room temperature but softens to a flowable state at application temperature, and an adhesion promotion system. Optionally a filler, wax, heat stabilizer, pigment, wetting agent, or mixtures thereof may be added. The individual components work synergistically to get good application properties, metal adhesion, wash-out resistance, and paintability.

    摘要: Eine spritzbare Plastisolzusammensetzung enthält 10 bis 60 Gew.% einer Mischung mit einer Teilchengröße unterhalb 60 µm aus einer ersten Polymerkomponente und einer zweiten schwach vernetzten Polymerkomponente, wobei die erste Polymerkomponente nach dem Gelieren als kontinuierliche Phase vorliegt und die zweite Polymerkomponente nach dem Gelieren als darin dispergierte diskontinuierliche Phase vorliegt, 15 bis 65 Gew.% mit der ersten Polymerkomponente verträglichen Weichmacher, der mit der zweiten Polymerkompo­nente unverträglich ist, und 0 bis 40 Gew.% Füllstoffe. Die Zusammensetzung eignet sich besonders zur Verwendung für die Schalldämpfung von schallabstrahlenden Flächen.

    摘要: Poly(vinyl chloride) plastisol compositions modified with epoxy and acid anhydrides can be painted wet-on-wet with acid catalyzed, high solids enamel paints, followed by curing at 120°C or lower, to give strongly adherent products on electrodeposition coatings and dry, tack-free painted surface. The compositions are also stabilized by the addition of an imide, which provides storage stability at 40°C for more than three days.
