  • Self cross-linking N-methylol functional emulsion polymers using polycarboxylic acid surfactant
    Patent number: 4229336
    Abstract: This invention relates to self cross-linking aqueous emulsion coating compositions comprising water and an emulsion polymer emulsified therein, and methods for their production. The emulsion polymer is comprised of copolymerized monomers including at least about 3 percent by weight of a C.sub.2 -C.sub.8 saturated alcohol ether of a monoethylenically unsaturated N-methylol functional monomer. The monomers making up the emulsion copolymer are emulsified during copolymerization by a polycarboxylic acid emulsifying agent which is partially neutralized with a volatile base to provide a pH of at least about 4.

  • Aqueous emulsion thermosetting coating compositions
    Patent number: 4137205
    Abstract: Aqueous emulsion thermosetting coating compositions possessing superior flexibility and room temperature coalescence are provided by combining certain aqueous emulsion copolymers including hydroxy and carboxy functionality, aminoplast resin and water dispersible high boiling polyhydric adduct of an aliphatic polyhydric alcohol containing from 2-4 hydroxyl groups with a monoepoxide or a lactone.

    Assignee: DeSoto, Inc.
    Inventors: Donald J. Berenschot, Dale F. Anders, Fred D. Hawker
  • Aqueous dispersion thermosetting coating compositions based on aqueous emulsion copolymers containing two sources of hydroxy functionality
    Patent number: 4132688
    Abstract: Aqueous dispersion thermosetting coating compositions are provided which bake to provide hard and flexible glossy coatings, the dispersion including an aqueous emulsion copolymer of ethylenic monomers including from 5-30% of non-nitrogenous hydroxy functional ethylenic materials, part of which are monomeric, and part polymeric, the ethylenic monomers being preferably copolymerized in admixture with organic mercaptan. The dispersion further includes aminoplast resin to cure the copolymer through its hydroxy functionality.

  • Process for anodic electrodeposition of aqueous emulsions
    Patent number: 4104100
    Abstract: Monoethylenic monomers are copolymerized in aqueous emulsion in the presence of about 0.5-5% of a polyanionic phosphate-based emulsifying agent to provide a stable aqueous emulsion which electrodeposits at the anode to form a continuous film of high quality.
    Type: Grant

  • High gloss latex coatings containing mercaptan-terminated emulsion copolymer and dissolved carboxyl-functional resin salt
    Patent number: 4081416
    Abstract: Pigmented thermosetting aqueous latex coating compositions adapted to deposit coatings which cure on baking to provide superior gloss are provided using an aqueous latex of hydroxyl-functional and mercaptan-terminated aqueous emulsion copolymer particles, the aqueous continuum of the latex having dissolved therein a carboxyl-functional resin salt. An aminoplast resin is dispersed in the aqueous latex to enable the thermosetting cure to take place.
