Black no-rinse conversion coating
Black No-Rinse Conversion Coating U.S.Patent5,470,673. Nov. 28, 1995 E.A. Rodzewich,assignor to Befz Laboratories Trevose, Pa.
Inc.,
A method of forming a black conversion coating on surfaces of aluminum and its alloys, comprising coating the surface with a coating solution having a pH below 7 consisting essentially of 0.01 to 0.20% hexavalent chromium; 2.0 to 10% acrylic/ itaconic modified styrene butyl acrylate polymer resin (as solid); 0.5 to 3.0% carbon black pigment; 0.2 to I .O% fluoacid; a thickening agent selected from the group consisting of guar gum and xanthan gum and drying the coating on the surface without rinsing; and optionally a nonionic dispersant and/or a slow evaporating coalescent.
Hard Anodic Coating for Magnesium Alloys U.S.Patent 5,470,664.Nov.28, 1995 D.E. Bartak et al., assignors to Technology ApplicationsGroup, Grand forks, ND. .4 magnesium-containing article offering improved corrosion and abrasion resistance, the article comprising a magnesiumcontaining substrate coated with a first layer containing a continuum of magnesium fluoride, magnesium oxide, magnesium oxofluoride, and silicon oxide.
Architectural
Material
amine pentaacetic acid, 1,3diamino-2-hydroxypropane-N,N,N[SA],N[SA]-tetraacetic acid, nitrilotriacetic acid, triethylenetetra-amine hexaacetic acid, N-(2-hydroxyethyl)ethylenediamine triacetic acid, 1$acetonedicarboxylic acid, 2-nitrobenzoic acid, or a salt thereof; inserting an anode and a cathode into the solution; wherein the cathode comprises the substrate; and creating an electrical potential at -0.5 V or less with a current density of at least I5 mA/cm’ to cause electrodeposition of the elements onto the cathode.
Water-Based
Acrylic
ionic or potentially ionic moeity counter ions capable of reacting with the carboxylate groups.
Paint Pump U.S. Patent 5,472,318. Dec. 5, 1995 PL. Frank et a/., assignors to Wagner Spray Tech Corp., Minneapolis
A rupture disk pressure relief assembly for a piston-type paint pump.
Coating Process for Cleaning and Tin
U.S. Patent 5,470,908. Nov. 28, 1995 D.L. Schmidt et al, assignors to The Dow Chemical Co., Midland, Mich.
A composition comprising at least 10% by weight of water and 0 to 95% of a water-compatible polymer having at least two pendant carboxylate groups; 1 to 60% of a different polymeric polycarboxylate, which has at least two pendant carboxylate groups and at least one internal amide, thioamide, urea, thiourea, biuret, dithiobiuret, or urethane group; and 2 to 70% of a polyfunctional crosslinking agent having
Aluminum
U.S. Patent5,472,512. Dec. 5, 1995 V.A. Gober and D.A. Raney assignors to Man-Gill Chemical Co., C/eve/and
A process for washing an aluminum or tin container, which comprises using an aqueous alkaline cleaner containing 20 to 75% by weight of at least one inorganic base, 1 to 30% by weight of at least one cationic surfactant, which is a quatemary ammonium compound, and water; rinsing; and drying.

to The
.4 metal strip unwound from a roll of strip and coated in a continuous hot dip process forming a coating with a highly corrosive-resistant, two-phase tin-zinc colored metallic coating, said coating comprising at least 65% zinc, at least 15% tin and at least 0.01% metallic stabilizer wherein said stabilizer is a metal selected from the group consisting of bismuth, antimony, and mixtures thereof.
KLN Supplies’ new Graystone Lining offers many advantages over ordinary lined tanks. Graystone has no seams, therefore, there is no chance of failure due to improper sealing. Also, because there are no seams, there is no chance of cutting through a seam when cleaning a tank or removing parts...Graystoneis bondedat high temperature to the steel after proper treatment. This limits undercutting from chemicals if the liner integrity is ever compromised. Graystone is patchable “on-site” and can be heat welded.
Electroplating of Superconductor Elements
If your KLN “Graystone”lined tank should fail during the 2-year period starting with the date of delivery, KLN at our option will repair/replace or issue credit for the cost of the tank. Call for details.
U.S. Patent 5,470,820. Nov. 28, 1995 R.L. Hauser et al., assignors to Hauser Chemical Research Inc., Boulder, Co/o.
A process for concurrent electroplating of yttrium, barium, and copper elements from aqueous solution onto an electrically conductive substrate comprising dissolving compounds of the elements in water containing complexing agent and adjusted to a pH of 5 or less, said complexing agent selected from the group consisting of picolinic acid, ethylenedamine-N,N[SA]-diacetic acid, diethylenetr-
