  • Publication number: 20040076847
    Abstract: A colored polymer/wood composite, e.g., plastic lumber, formed by shaping a blend of a thermoplastic polymer and wood particles, e.g., wood flour, which has been colored by mixing with an aqueous dispersion of a pigment or an aqueous solution of a dye as a pretreatment, so that the pigment particles or dye are thoroughly absorbed into the fiber matrix of the wood particles, followed by drying. Preferably, the foregoing pigment dispersion or dye solution used to pretreat the wood particles also contains an effective amount of at least one member selected from the group consisting of light stabilizers, U.V. absorbers, antimicrobial agents including biocides, and antioxidants. The composite has a reduced tendency to fade or whiten with time.

  • Patent number: 4581293
    Abstract: Disclosed is an epoxy rubber made by reacting about 5 to about 50% of an epoxy terminated acrylonitrilebutadiene copolymer with about 50 to about 95% of a solid epoxy resin. A coating powder is prepared with about 30 to about 70% of a solid epoxy resin, about 2 to about 25% of the epoxy rubber, about 5 to about 25% of an anhydride curing agent, about 5 to about 40% mica filler, and about 10 to about 50% glass fiber. Electrical apparatus, such as coils made of served wire, can be coated with the powder by heating the apparatus above the melting point of the powder and dipping it in the fluidized powder, followed by curing the melted powder on the apparatus.

  • Patent number: 4479990
    Abstract: A photosensitive sag resistant composition is made containing cycloaliphatic epoxy resin, a flexibilizing agent, arc and track resistant filler, thixotroping agent, and an amount of a photosensitive compound effective to initiate gelation with ultraviolet light exposure, where the composition is resistant to sag upon application to a surface, and has chemical and physical resistance to arced SF.sub.6 upon cure.

  • Patent number: 4447797
    Abstract: Disclosed is a conductor coated with a fused and cured powder applied insulating coating over which is a coating of an ultraviolet B-stageable, thermally C-stageable liquid resin. The coating is cured to the B-stage and strands of the conductor are placed side-by-side. The coating is then cured to the C-stage which fuses the strands of the conductor into a solid mass. The adhesive coated conductors may be used to form transformer coils, transposed cables, or other articles.

  • Patent number: 4412048
    Abstract: Disclosed is a solventless UV dryable B-stageable epoxy adhesive which comprises about 40 to about 70 pbw of a solid thermally curable epoxy having a molecular weight between about 650 and about 4000, a thermal curing agent for the thermally curable epoxy which is stable at room temperature and soluble on the adhesive in an amount of about stoichiometric to about 50% by weight in excess of stoichiometric, up to about 2 pbw of an accelerator for the thermal curing agent which is soluble in the adhesive, about 25 to about 60 pbw of a liquid UV curable resin having a molecular weight of less than about 700 which is either an epoxy, an acrylic, or a mixture thereof and which is a diluent for the thermally curable epoxy, about 1 to about 10 pbw of a UV photoinitiator for the UV curable resin, up to about 20 pbw of a reactive diluent, up to about 5 pbw of a flow control agent, up to about 1 pbw of a surfactant, and up to about 10 pbw of a tri or higher functional epoxy.

  • Patent number: 4241101
    Abstract: A coating powder is disclosed which is prepared from a solventless non-aqueous composition of a solid epoxy resin having an epoxy equivalent weight of about 400 to about 8000, a Durran's softening point of at least 70.degree., a solid polyanhydride curing agent at least about 50 mole % of which is trimellitic anhydride, and a cross-linking agent having the general formula R.sub.3 SnX where each R is selected from alkyl, aryl, aralkyl, and alkaryl up to C.sub.20 and X is selected from acetate, propionate, butyrate, halogen, and hydroxyl. The composition is dry-blended and then melt-mixed at 50.degree. to 150.degree. C. To prepare the coating powder, it is then cooled, crushed, and ground to a particle size of less than 100 microns. The coating powder is electrostatically applied to a conductor and is cured above the melting point of the resin.
