  • Patent number: 6803400
    Abstract: Water-swellable hot-melt adhesives based on a tackifying resin, a water-dispersible EVA wax, an ethylene/acrylic ester copolymer, a water-soluble homo- or co-polymer and a super absorber polymer powder having an average particle size of less than 80 &mgr;m display a clearly improved swelling behavior in comparison with the prior art. Furthermore, the swelling agent is significantly more homogeneously distributed in the matrix. Such hot-melt adhesives are suitable for ensuring longitudinal water impermeability in modern cable structures, as water-swellable jointing compounds in the building industry in the area of building conservation and restoration. Such hot-melt adhesives are further suitable for the manufacture of absorbent textile fabrics in the personal hygiene sector.

  • Patent number: 6743756
    Abstract: Liquid suspensions of particles in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed particles. The suspensions enable a user to rapidly add the suspension to water and to mix at low speeds without generating fugitive dust in the process. In addition, a liquid dispersion can provide an easy to use liquid containing higher concentrations of the active dispersed phase than can be accomplished by simply preparing an aqueous solution of the dispersed phase. Alternatively, highly water-soluble particles may also be suspended which have poor storage, freeze/thaw, or heat/cool stability. In some cases, liquid dispersions can yield controlled release of the dispersed phase because the dispersed phase is not in aqueous solution. The suspensions are environmentally safe and biodegradable and may be used in environmentally sensitive applications, such as for oil well treating fluids for offshore areas.

    Abstract: Waxes prepared from hydrogenated plant oils, such as palm and soybean, are used as substitutes for petroleum derived waxes in hot-melt adhesive compositions. Unlike petroleum-derived or synthetic waxes, adhesive compositions comprising these waxes, which are obtained from naturally derived, renewable resources, achieve adhesion performance similar to conventional adhesives containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-165 degrees F. (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acids are predominantly stearic acid (C18). The naturally derived waxes are used as an alternative to petroleum and synthetically derived waxes in the manufacture of adhesives used to bond paper, wood, glass, plastic and metal in a variety of manufacturing operations.

  • Patent number: 6384120
    Abstract: A synthetic resin film for agriculture suited as a covering material for greenhouses or the like, which shows good anti-clouding and anti-fogging properties immediately after being spread and for longer period than 2 years. The synthetic resin film for agriculture is obtained by using (a) an ester of sorbitan with a higher fatty acid mainly containing 24 to 34 carbon atoms (montanic acid wax), an ester of glycerin with montanic acid wax and/or alkylene oxide adducts thereto and/or an ester of polyoxyalkylene with montanic acid wax as an anti-clouding agent, and (b) a fluorine-containing surfactant as an anti-fogging agent, kneading them with a film-forming resin such as vinyl chloride resin, polyethylene, ethylene/vinyl acetate copolymer, and forming it into a film.
