  • Water-dilutable coating of oh-acrlylate or polyesterurethane resin and blocked acid catalyst
    Patent number: 6462124
    Abstract: A base-neutralized, water-diluted coating comprises (A) a polyhydroxyl-functional resin of an acrylate resin or an oil-free polyester containing urethane groups, (B) an amino resin partially etherified with an alcohol, (C) a basic neutralizing agent, (D) water, and (E) a water-insoluble crosslinking catalyst of a strong organic or inorganic acid such as p-toluenesulfonic acid blocked with a monoepoxide, diepoxide or lactone.

  • Oven-drying coating materials which are water-dilutable after neutralization with bases
    Publication number: 20010018494
    Abstract: The invention relates to enamels which are water-dilutable after neutralization with bases and which contain non-ionically blocked strong acids as the cross-linking catalysts. In comparison with enamels with ionically blocked strong acids, the hardened enamel films exhibit no wrinkling and improved acid-resistance.
    Type: Application

  • Water-dilutable coating composition of polyhydroxyl condensation or addition resin, amino resin and blocked acid catalyst
    Patent number: 6204332
    Abstract: A water-dilutable coating after base neutralization comprises a polyhydroxyl-functional resin including a condensation resin such as a polyester or alkyd resin, and/or a polyhydroxyl-functional addition resin such as an acrylate resin or the reaction product of a carboxyl-functional acrylate resin and a hydroxyl-functional acrylate resin, and/or an emulsion copolymer, an at least partially monoalcohol-etherified amino resin, and a strong organic or inorganic acid crosslinking catalyst non-ionically blocked with a monoepoxide, a diepoxide or a lactone.
