Wax Having Melting Point Above 120 Deg. F (49 Deg. C) Patents (Class 524/489)
  • Patent number: 4456649
    Abstract: This invention relates to holt melt adhesives for use in coating and/or laminating paper. Conventional hot melt adhesives used to manufacture a coated or laminated product with good vapor barrier characteristics are based on ingredients compounded with significantly lower proportions of inert low cost filler materials. The present invention provides a hot melt adhesive/coating blend which not only provides a moisture vapor barrier and/or bonding but also significantly reduces the quantity of more expensive ingredients through the use of a large quantity of a lower cost ultra fine ground inert inorganic filler material and a low cost modifying hydrocarbon resin. The blend or composition consists essentially of, in parts by weight, up to about 25 parts of a hi melt point paraffin wax, 10-30 parts of a modifying hydrocarbon resin, 1-20 parts of an elastomeric copolymer, and 20-85 parts of an inert inorganic filler material.

  • Patent number: 4439563
    Abstract: A concrete cure is provided which is totally water based and completely void of solvents. A moisture impermeable film is attained when the cure is applied to fresh concrete. The cure forms a barrier over the concrete allowing it to retain over 95% of the mixing water for a minimum of 72 hours when applied at the rate of 200 ft.sup.2 /gallon (5m.sup.2 /dm.sup.3). The concrete cure of the invention is a mixture of a hydrocarbon resin, emulsifying agents, paraffinic wax, and water. The cure may be provided in a clear or pigmented formulation. A method for making the concrete cure is also disclosed.

  • Patent number: 4439575
    Abstract: Aqueous varnishes containing mineral fillers and/or pigments are prepared by allowing a hot wax emulsion in water at between 80.degree. C. and 100.degree. C. to flow with vigorous stirring into the aqueous varnish containing mineral fillers and/or pigments and to cover at least some of the filler and/or pigment particles with a wax coating. These varnishes show virtually no sedimentation of the solid constituents.

  • Patent number: 4401782
    Abstract: Non-aqueous, quick setting sizing compositions suitable for application as a melt to textile yarns, and for later removal by solvent or aqueous means, characterized by substantial amounts of hydrogenated tallow-type triglyceride wax, are disclosed. The compositions may include an approximately 50:50 weight mixture of a specific class of 80/20 ethylene/acrylic acid copolymers intimately blended with an equal amount of the wax. A fatty acid amide may be included in an amount up to about 7 weight percent of the composition or from 1 to 14 weight percent sebacic acid or dodecanedioic acid, the amount of copolymer being reduced accordingly. The compositions may contain up to 62 weight percent of the wax, and rigidify at ambient temperatures.
