  • Patent number: 4199489
    Abstract: In a preferred embodiment, an improved high solids polyurethane paint composition contains metallic flake pigment and a binder comprising a particular isocyanate-terminated polyether-urethane resin. The resin is formed by reacting an excess of a suitable aliphatic diisocyanate with a suitable mixture of polyoxypropylene diols and triols and a hindered piperidine type UV stabilizer in the presence of an organotin catalyst. The product urethane resin having the stabilizer reacted into its molecular structure is formulated with color producing pigments, metallic flakes and a suitable solvent to produce a composition having a nonvolatiles content of 60 to 70 weight percent. The composition is spray applied to a substrate and moisture cured to provide a decorative topcoat wherein the flakes lie at varying depths and are oriented substantially parallel to the topcoat surface.

  • Patent number: 4199491
    Abstract: Since their surfaces are inactive, polyolefin resins are difficult to plate. A plating method utilizing sensitizing-activation of the surface has been used for plating polyolefin resins. Many attempts have been made to improve the plating properties of the surfaces of polyolefin resins, for example, a mechanical method, a method employing a solvent, a method of coating other types of resins on the surface, etc. As methods modifying the plastics themselves, there are several; a method of introducing polar radicals by graft polymerization, etc., a method of introducing atactic polypropylene or block copolymer of polypropylene and polyethylene, a method of mixing rubber or a copolymer of ethylene and vinyl acetate, a method of mixing in an inorganic filler, etc.

  • Patent number: 4197225
    Abstract: This application concerns compositions comprising a mixture of air-drying dicyclopentenyl acrylate or methacrylate binder and a granular or particulate aggregate material, which may comprise a hydraulic cement, and is adapted to be formed by casting, extruding, or molding in any fashion into any desired shape and air-drying and resulting shaped article, thereby producing an integral, solid article of unitary mass and structure. The dicyclopentenyl (meth)acrylate may be used as an impregnant, polymerizable in situ, for already formed articles of porous nature, e.g., concrete, wood, pressed boards, and powdered pressed metal, such as aluminum, iron, steel, etc., to reduce the permeability at their surfaces and provides hard, continuous, hydrophobic, wear-resistant, and weather-resistant surfaces thereon.

  • Patent number: 4197234
    Abstract: Polyfluorocarbon resin or polychlorofluorocarbon resin, especially polytetrafluoroethylene in powder form is added to a conventional inert inorganic finely divided filler for dental restorative composite compositions, in combination with conventional liquid polymerizable binder systems to provide a composite composition possessing improved mechanical properties, especially wear or abrasion resistance. As little as 1.0% by weight or less of the total weight of filler of the polyfluorocarbon or polychlorofluorocarbon resin powder imparts improved wear. Abrasion superior to conventional amalgams suitable for use on occlusal surfaces resistance is achieved.

  • Patent number: 4195001
    Abstract: Formulations, and process, particularly for temporarily, but effectively, stopping leaks in tanks or pipes and the like through which liquids such as gasoline, oil, water or similar liquids are running or flowing, at low pressures, until a permanent repair of the leak of crevice through which said liquid is seeping can later be made. The formulations are in the form of two separate compositions, each of which is of generally putty consistency, which are blended together just prior to use to form a product having a putty or putty-like consistency which is pressed into the area through which leakage of the liquids is occurring. The formulations, when blended together or admixed for use, contain one or more epoxy resins, one or more epoxy curing agents, one or more waxes or waxy materials, and, advantageously, one or more fillers, with or without minor proportions of one or more supplemental ingredients.

  • Patent number: 4192791
    Abstract: A highly extended,unsaturated polyester resin syrup composition mixture comprising unsaturated polyester resin syrup, basic aluminum chloride and non-reinforcing extender material which is substantially non-reactive with the resin syrup and the basic aluminum chloride. The composition mixture may be used to prepare a shaped article comprised of the cured, cross-linked composition. The article is prepared by first forming a first component comprising unsaturated polyester resin syrup and non-reinforcing extender material and a second component comprising a solution of basic aluminum chloride and non-reinforcing extender material. The two components are mixed together to yield the composition mixture which possesses a viscosity low enough to be worked with conventional apparatus. The composition mixture is then shaped into the configuration of the desired article, allowed to cure and, if necessary, allowed to set.
