| New Pyro-Paint high temp refractory coating Pyro-Paint 634-ZO, a new high temperature, zirconium oxide filled refractory coating developed by Aremco Products is used to coat and extend the life of ceramic, graphite and metal crucibles and molds use in foundry applications to 3270°F. Pyro-Paint 634-ZO is a high purity, zirconium oxide filled, water-based, chemically resistant coating system used to extend the life of ceramic, graphite and metal crucibles and molds used in the handling of molten metals in applications to 3270°F. Pyro-Paint 634-ZO exhibits high adhesion to ceramics, graphites and metals and is resistant to wetting by a wide range of metals including Steels, Acidic Slags, Al, Pt, Rh, Zr, Nb, Mo, W, U, Ti, Pd and Ru. Pyro-Paint 634-ZO provides excellent durability and erosion resistance. Pyro-Paint 634-ZO is formulated with a solids content of 54.0% by weight and 32.4% by volume to a viscosity range is 3,000 to 5,000 cps. It is typically applied by brush, roller or conventional spray equipment. Dry films up to 5-10 mils can be produced without cracking. Cured films are greater than 95% pure zirconium oxide. Pyro-Paint 634-ZO is a simple to use, environmentally friendly, water-based formulation containing no volatile organic compounds. It dries at room temperature in several hours and cures fully within 2 hours at 200°F. write your comments about the article :: © 2007 Construction News :: home page |
