  • Patent number: 4118437
    Abstract: A polymeric finely-divided powder coating composition comprising a homogeneous blend of certain quantities of a solid polymeric material having a comparatively low molecular weight and containing certain reactive groups blended with certain quantities of tetrakismethoxymethylglycoluril.
    Type: Grant
    Filed: April 8, 1976
    Date of Patent: October 3, 1978
    Assignee: American Cyanamid Company
    Inventor: Girish Girdhar Parekh
  • Patent number: 4064191
    Abstract: An organic solvent based composition comprising a blend of certain quantities of a partially or fully alkylated glycoluril blended with certain organic solvent dispersible non-gelled, non-self-crosslinking polymeric materials containing only certain reactive groups and catalyzed with small quantities of an acid catalyst which will cause the glycoluril derivative to crosslink with the polymeric material, when subjected to heat.
    Type: Grant
    Filed: March 10, 1976
    Date of Patent: December 20, 1977
    Assignee: American Cyanamid Company
    Inventor: Girish Girdhar Parekh
  • Patent number: 4026855
    Abstract: The disclosure relates to a composition of matter comprising a blend of an ungelled modified cross-linking agent, certain water-dispersible non-gelled polymeric materials carrying a cationic charge and an acid solubilizer in certain stated proportions. The disclosure also relates to the use of these compositions of matter in the process of electrodepositing films on an electrically conductive surface which comprises passing an electric current between a cathode comprising said surface and an electrically conductive anode immersed in an aqueous dispersion of said composition.
    Type: Grant
    Filed: October 20, 1975
    Date of Patent: May 31, 1977
    Assignee: American Cyanamid Company
    Inventors: Girish Girdhar Parekh, Werner Josef Blank
  • Patent number: 3984382
    Abstract: A modified cationic vinyl polymer prepared by the copolymerization of a polymerizable styrene, maleic anhydride and an alkyl acrylate, which polymer is then reacted with certain amino alcohols and/or certain difunctional amines containing a tertiary nitrogen atom followed by reaction with certain monoepoxy compounds. The modified vinyl polymer finds utility in electrocoating applications, particularly for anodic-soluble metals, such as copper and copper alloys wherein the vinyl polymer, in amounts varying between about 40% and 95%, by weight, is combined with about 4.0% to about 50%, by weight, of a substantially fully etherified, substantially fully methylolated aminotriazine cross-linking agent and from about 1% to about 20%, by weight, of a neutralizing agent such as a mineral acid or an organic acid in an aqueous dispersion.
