  • Patent number: 8686092
    Abstract: A series of resins were synthesized using a range of bio-based materials to control the molecular architecture, and therefore the properties, of the inventive resins. The utility of these resins was demonstrated in the formulation of powder coatings, such as ?-hydroxy amide crosslinked and hybrid types. Generally, the bio-based resins flowed out on heating faster than conventional petrochemically-based resins, allowing the use of lower temperatures in the curing oven than is typically possible and a more active catalyst system, especially in the carboxylic acid-epoxy crosslinked hybrid coating formulations.

  • Patent number: 8609767
    Abstract: Toughened thermosetting resins comprising thermosetting resins and rubber particles having an average particle size in the range of 20 to 500nm. The toughened resins are obtained by mixing a fully vulcanized powdery rubber having an average particle size in the range of 20 to 500nm with thermosetting resin prepolymers and then curing them. The toughened thermosetting resins comprise rubber phases having a small, uniform and stable particle size, which results in a very significant toughening effect, especially when crazes rapidly grow (as in a standard Izod impact test). The toughened thermosetting resins are excellent in impact resistance, strength, modulus and heat resistance, and when appropriately toughened, the thermosetting resins can be enhanced in terms of impact strength, glass transition temperature and heat distortion temperature.

  • Patent number: 7138457
    Abstract: A mixture of a polyester, such as poly(ethylene terephthalate) PET, and a suitable stabilizer selected from the group consisting of polyhydric alcohol-containing polymers and copolymers derived from 2-propenoic acid ester monomers, when extrusion compounded exhibits a lower residual acetaldehyde content than does PET alone when similarly treated. The invention pertains to any polyester used in the manufacture of bottles or containers which in turn are used to store consumer materials, especially food, beverages and most especially water.

  • Patent number: 7041737
    Abstract: The present invention provides a low temperature curing coating powder composition comprising a mixture of a high gloss film-forming system and a low gloss film-forming system. Preferably, the high gloss film-forming system comprises a GMA (glycidyl methacrylate) resin, a curing agent, and a catalyst and forms a coating having a gloss greater than 80% measured at 60°. Preferably the low gloss film-forming system comprises a carboxyl terminated polyester, acrylic resin and a catalyst and forms a coating having a gloss less than 50% measured at 60°. The composition of the present invention provides coatings having a control gloss, which can range from a low to a high gloss and is useful for coating heat-sensitive substrates.

  • Patent number: 7034075
    Abstract: The invention is directed to a low gloss powder coating composition comprising a first component (a) and a second component (b). The first component (a) comprises a mixture of (i) at least one glycidyl group-containing acrylic resin having epoxide equivalent weight of from about 250 to about 1500 and glass transition temperature of from about 30° C. to about 80° C.; and (ii) a curing agent. The second component (b) comprises at least one carboxyl-group containing material having acid number of from about 10 to about 300 and is not substantially compatible with the first component (a). The two components are dry-blended to obtain the powder coating composition.

  • Patent number: 6995194
    Abstract: A radiation curable powder coating composition is disclosed, which comprises a blend of (meth)acryloyl group containing polyphenoxy resin, a (meth)acryloyl group containing resin other than the polyphenoxy resin and other than a (meth)acryloyl group containing amorphous polyester and, eventually, a (meth)acryloyl group containing monomer or oligomer. These powders give coatings with improved chemical resistance and flexibility.

  • Patent number: 6878776
    Abstract: The invention relates to thermosetting compositions, in particular coating or molding compositions, comprising crosslinked polymer microparticles with a size ranging from 10 to 300 nm and carrying at least one reactive functional group which can react with at least one of the reactive components of the thermosetting composition. Preferably, these microparticles carry at least one second reactive functional group distinct from the first which can react with at least one other functional group of the same type carried by another microparticle and/or by a reactive component of the thermosetting composition. These microparticles are at least partially soluble, miscible and/or dispersible in the starting thermosetting composition. The preferred thermosetting compositions are based on resins of epoxy/amine type or on unsaturated polyester resins and/or on vinyl ester resins.

  • Patent number: RE39617
    Abstract: Hydrogenated butadiene polymers having terminal functional groups have minimum viscosity at any molecular weight when the 1,2-addition is between 30% and 70% Hydrogenated butadiene polymers having about two terminal hydroxyl groups per molecule have surprisingly lower viscosities at 30% to 70% 1,2-addition than similar polymers having either higher or lower amounts of 1,2-addition. The polymers are useful in making coatings, sealants, binders, and block copolymers with polyesters, polyamides, and polycarbonates.
