    摘要： A method of forming a multilayer coating on a substrate utilizes a pigmented aqueous based coating composition. The aqueous based coating composition contains a polymeric film-forming resin and as an additive from about 1 to about 40 percent by weight based on the resin solids of the composition of an oligomeric ester having an acid value of from about 100 to about 500 of the structure: ##STR1## where X is the residue of a polyol containing from 1 to 50 carbon atoms per hydroxyl group after reaction with an acid or an anhydride, R is an organic moiety from the acid or anhydride and A has an average value of about 2 or greater. The coating compositions are particularly advantageous as metallic pigmented coating compositions for automotive basecoat applications because they exhibit excellent resistance to mottling, have good flop and have reduced sensitivity to fluctuations in relative humidity.

    摘要： Ungelled hydroxyl-containing oligomers and their method of preparation are disclosed. The oligomers can be prepared by reacting an organic isocyanate with a half-ester formed from reacting a polyol with a 1,2-dicarboxylic acid anhydride followed by reaction with an epoxide. The oligomers are useful as resinous binders in high solids coating compositions. The coating compositions can be applied by spraying and do not result in a tacky overspray common with many high solids coating compositions.

    摘要： Quaternary ammonium hydroxide-containing polymers and their use in cationic electrodeposition are disclosed. The quaternary ammonium hydroxide-containing polymers are particularly useful as feed resins for controlling the pH of aqueous dispersions of acidified cationic resins used in electrodeposition. Upon electrodeposition, such resins generate acid which can build up to undesirable levels in the electrodeposition bath. The quaternary ammonium hydroxide-containing polymers are strong bases and when fed into the bath react with the acid to form the corresponding quaternary ammonium salt. This controls the pH of the bath at acceptable levels and provides additional cationic resin for electrodeposition. Utilizing the invention in this manner minimizes the need for controlling acid build-up in the electrodeposition bath by conventional techniques such as by treating the bath with ultrafiltration or electrodialysis.The quaternary ammonium hydroxide-containing polymers are also useful as electrodeposition resins themselves in that they electrodeposit without generating acid counter ion.

    摘要： The potlife of an ambient temperature, moisture-curable coating composition comprising an acrylic-silane interpolymer and a cure-accelerating catalyst is increased by the addition to the composition of from about 0.5 percent to about 15 percent by weight of interpolymer solids of a monomeric hydrolytically reactive organo-silicon compound represented by the structural formula:X.sub.n Si(OR).sub.4-nwherein X is an organic radical having from 1 to 12 carbon atoms, R is methyl, ethyl, 2-methoxyethyl, 2-ethoxyethyl, or an acyl group containing 5 or less carbon atoms and n is 0, 1 or 2.
