  • Method of coating coils using a high solids fluorocarbon coating composition
    Patent number: 6858258
    Abstract: A coating composition which includes an aminoalkyl (meth)acrylate containing acrylic polymer, a fluorocarbon polymer and a solvent. The acrylic polymer includes at least one (meth)acrylate monomers and an aminoalkyl (meth)acrylate monomer described by the structure: where Z is a divalent linking group; R2 and R3 are independently selected from H or C1-C6 linear or branched aliphatic; and R4 is H or CH3. The fluoropolymer coating composition may be applied using coil coating, spray coating or extrusion coating methods to an appropriate substrate.
    Type: Grant

  • Polyisocyanate cured ultradurable glossy coating compositions
    Patent number: 5849835
    Abstract: A curable, film-forming composition is provided which includes: (a) a hydroxyl-containing acrylic solution polymer, and (b) a polyisocyanate crosslinking agent. The hydroxyl-containing acrylic solution polymer is present in an amount ranging from between about 60 to about 90 weight percent; and, the polyisocyanate crosslinking agent is present in an amount ranging from between about 10 to about 40 weight percent. The acrylic solution polymer is the reaction product of: (a) a cycloaliphatic and/or aromatic ester of (meth)acrylic acid having at least 6 carbon atoms in the cycloaliphatic and/or aromatic group, and (b) a hydroxyl functional acrylic monomer component. The hydroxyl functional acrylic monomer component is present in an amount such that the hydroxyl number of the resulting acrylic solution polymer is less than 60. This invention also provides a color-plus-clear coating system.
