  • Patent number: 6136119
    Abstract: This invention relates to thermoplastic, pressure-sensitive solid adhesives capable of transferring an adhesive film to a substrate by friction rubbing of the adhesive on the substrate. The adhesives of this invention consist essentially of polyisobutylene, wax and optionally an adhesive promoter resin. Said ingredients are within certain proportions, molecular weights, melting points, or hardness values.

  • Patent number: 6127518
    Abstract: Method of producing dry polyvinyl acetate particles that are readily dispersible in water, are vinyl acetate monomer free and are useful for making polyvinyl acetate dispersion compositions that are low in odor, form clear dried films and may be used in adhesives, sealants, caulks and coatings. The method includes manufacturing an aqueous, e.g. water, dispersion of polyvinyl acetate containing polyvinyl alcohol; drying to remove volatiles by converting the dispersion to dry form under controlled temperature conditions and redispersing the dried polyvinyl acetate particles in an aqueous medium to form a polyvinyl acetate dispersion that is substantially free of vinyl acetate monomer.

  • Patent number: 6066689
    Abstract: Adhesive compositions exhibiting fast cure time in solid form, e.g. in the form of an applicator crayon or glue stick. The adhesive exhibiting polymer of the composition is based on a mixture of critical amounts of high molecular weight polyvinylpyrrolidone polymer, with a lower molecular weight polyvinylpyrrolidone polymer, with water, an organic solvent, and a salt of a long-claim fatty acid, e.g. sodium stearate. Color indicators and other optional ingredients, e.g. mildewcide, can be included.
