  • Solid paints coated substrates
    Patent number: 4078116
    Abstract: Dimensionally stable solid paints formed by interaction of certain polymers having acid group functionality with a substantial excess of a solution of ionic cross-linking reactants in a polar solvent are especially useful for the interior decorating and protection of structural components including wood, wall board, plaster, plasterboard and similar surfaces.
    Type: Grant
    Filed: October 12, 1976
    Date of Patent: March 7, 1978
    Assignee: SCM (Canada) Limited
    Inventor: Alfred Norman Dunlop
  • Solid paints
    Patent number: 3994848
    Abstract: Solid paint compositions having dimensional stability based on ion bonding of discrete particles are obtained by reacting stabilized non-aqueous dispersions of certain resins having acid group functionality with a substantial excess in the order of 100 - 500 mole percent of a cross-linking reactant formed by solution of a metal hydroxide, ammonium hydroxide or cation former in a polar solvent of dielectric strength greater than 10.
    Type: Grant
    Filed: December 20, 1974
    Date of Patent: November 30, 1976
    Assignee: SCM (Canada) Limited
    Inventors: Alfred Norman Dunlop, Christopher Grant Rickard
  • Solid paints
    Patent number: 3994849
    Abstract: Solid paint compositions having dimensional stability based on ion bonding are formed by interaction of certain polymers, having acid group functionality and dissolved in non-polar solvents, with a substantial excess in the order of 100-600 mole percent of a cross-linking reactant formed by solution of a metal hydroxide, ammonium hydroxide or cation former in a polar solvent of dielectric strength greater than 10.
