  • Patent number: 5082922
    Abstract: A method is provided for producing a modified addition polymer from an ethylenically unsaturated monomer composition that includes at least one monomer having hydroxyl or carboxyl functionality. The ethylenically unsaturated monomer composition, and a free radical initiator therefor, is dissolved in a solvent-free molten composition maintained at an addition polymerization temperature, the molten composition comprising a cyclic compound reactive via ring-opening with the hydroxyl or carboxyl functionality. The resulting material is useful in the manufacture of paints in liquid or powder form.

  • Patent number: 5039740
    Abstract: An alkyd resin coating composition having reduced solvent requirements and excellent physical and cure properties is obtained by blending together a fatty acid-modified polyester resin and an addition-polymerizable monomer or oligomer characterized by vinyl unsaturation and capable of undergoing addition polymerization under free radical initiating conditions.

  • Patent number: 5027973
    Abstract: A container, such as a pail for holding paint or the like, integrally molded from a resilient plastic material. The container includes an integrally molded bail having ends joined to wall portions of the container by relatively thin, flexible, diametrically opposed hinge portions which enables the container and its liquid contents to hang vertically from the bail. A stiffening bead is provided circumferentially about the wall of the container adjacent its upper rim, the bead including a vertically extending, X-shaped lattice structure included between the wall of the container and a wall spaced annularly thereabout.

  • Patent number: 4981887
    Abstract: To improve chip resistance of an alkyd-type electro-depositable coating composition, there may be added to the composition an ethylenically unsaturated, addition-polymerizable monomer or oligomer having a substantially linear backbone, having a molecular weight of at least about 150, and being reactive with fatty acid unsaturation of the alkyd.

  • Patent number: 4914139
    Abstract: An alkyd-type electrodepositable coating composition derived from the reaction of a base alkyd with ethylenically unsaturated monomers including an amine-functional monomer is provided with improved resistance to chipping by chemically incorporating in it by covalent bonding one or more chemical agents selected from the group of:(a) preformed elastomers having functional groups reactive with carboxyl or hydroxyl groups of acid and polyol alkyl precursors, and(b) an addition polymerizable monomer having primary and secondary ethylenic unsaturation.

  • Patent number: 4670342
    Abstract: A method for making an electrical inductive device for use in hermetic atmospheres which incorporate refrigerants such as halogenated methane compositions, for example refrigerant R-22, monochlorodifluoromethane. The device may be a wound coil device formed of magnet wire, the enamel coating of which has resistance to blistering when exposed to refrigerants under saturated conditions at temperatures up to about 200.degree. or 210.degree. C. and above. The enamel coating composition or wire enamel is formed as the reaction product of 1,2,3,4-butanetetracarboxylic dianhydride, optionally with an aromatic dianhydride, and a diamine such as p,p'-methylenedianiline or p,p'-oxydianiline, in an organic solvent such as N-methyl-2-pyrrolidone.

  • Patent number: 4540751
    Abstract: The production of novel polyester resins is disclosed as is the preparation of high solids coatings and paints containing the same. The polyester resins are produced by reacting a mixture comprising:(a) A saturated fatty acid having from 8 to 18 carbon atoms in an amount between about 3 and about 8 percent;(b) A polyol in an amount between 40 and 50 percent, said polyol consisting of between about 55 and 75 percent of a triol with the remainder being a diol;(c) A polycarboxylic acid in an amount of about 45 to about 55 percent, said polycarboxylic acid consisting of between 65 and 75 percent of an aromatic polycarboxylic acid with the remainder being aliphatic acid having from 4 to 10 carbon atoms.The coatings and paints are preferably prepared by reacting the polyester resin with an aminoplast resin to cause cross-linking.

  • Patent number: 4511692
    Abstract: A cationic electrodeposition composition comprising the reaction product of one or more base alkyds, containing unsaturation of the fatty acid chains to provide oxidative curing and one or more ethylenically unsaturated monomers, and one or more amine functional monomers, which are added to the base alkyd and polymerized. This composition provides a vehicle which is hydrolytically stable. Paints are prepared by the addition of conventional driers, pigments and solvents to the vehicle composition.
