  • Publication number: 20110152408
    Abstract: Coating composition includes curable epoxy resin in solid form, curing agent for the epoxy resin, and filler. Further, there is a polyolefin containing component having a compatibilizer polymer that is a modified polyolefin, a mixture of a polyolefin or olefin copolymer with a functionalized rubber, or both. The modified polyolefin and functionalized rubber contain groups reactive with either the epoxy resin or the epoxy curing agent. A polyolefin-based portion that amounts to at least 50% by weight of the polyolefin containing component, and an epoxy-based portion that amounts to at least 50% by weight of the curable epoxy resin have viscosities such that the difference between the viscosity of the polyolefin-based portion and the viscosity of the epoxy-based portion, expressed as a percentage based on the lower of the two viscosities, is less than 40%. These viscosities are measured by ASTM D4440 at the Vicat softening points, as measured by ASTM D 1525.

  • Patent number: 7332069
    Abstract: The present invention provides a curable cathodic corrosion protection powder coating, which comprises a thermosetting resin, a zinc borate compound, a curing agent in an amount effective to cure the coating. Further, the present invention also provides a method of cathode corrosion protection which includes the steps of subjecting the substrate to a mechanical treatment, applying to said treated steel surface, the cathodic protective coating, and polarizing the coated material as a cathode.

  • Patent number: 7323234
    Abstract: The present invention provides a curable alkanolamine containing epoxy powder coating composition comprising at least one epoxy resin, at least one alkanolamine, a curing agent in an amount effective to cure the coating and optionally at least one zinc borate compound. Further, the present invention provides a method of cathode corrosion protection which includes the steps of subjecting a metal substrate to a mechanical treatment, applying the curable alkanolamine containing epoxy powder coating composition to the surface of the metal substrate, and polarizing the coated material as a cathode. The present invention also relates to a process for making and applying the alkanolamine containing epoxy powder coating compositions of the present invention.

  • Publication number: 20070293614
    Abstract: The present invention provides an epoxy powder coating composition comprising an intimate mixture comprising (A) 5 to 99 wt % of at least one bromine functionalized epoxy resin with a bromine content of 5 to 60 % based on component (A), (B) 0.5 to 40 wt % of at least one epoxy curing agent, and (C) 0.01 to 55 wt % of at least one pigment, filler and/or coating additive, the wt % based on the total weight of the powder coating composition. The powder coating composition of this invention provides coating with a high glass transition temperature and acceptable flexibility when coated on metallic or plastic substrates, particularly metallic and plastics pipelines. The coatings may have an improved adhesion under hot and humid conditions as well as an optimum short and long term high temperature and humidity cathodic disbondment protection.
