摘要： A water based thixotropic adhesive gel is disclosed which consists essentially of: water; partially hydrolyzed polyvinyl alcohol, or wherein a portion of the polyvinyl alcohol is replaced with polyvinylpyrrolidone; a water-soluble high viscosity thickening agent polymer which is compatible with the polyvinyl alcohol and which imparts thixotropic properties to the gel; a water-soluble plasticizer for the polyvinyl alcohol; and a water-soluble defoamer in proportion of ingredients so that the viscosity of the adhesive will break down when a flexible tube or squeeze bottle dispenser is finger-pressed and have a sufficiently low viscosity to allow for easy extrusion from an orifice having a diameter of about 0.06 to 0.15 inches. When pressure is released, after the desired amount of adhesive has flown out of the dispenser, the adhesive quickly reverts to very close to its original gel state so that it will not run on a vertical surface on porous and semiporous surfaces such as paper. An article of manufacture is also provided whereby the adhesive gel containing the above ingredients is in a flexible dispenser from which the adhesive can be dispensed by finger-pressure.

摘要： A cross-linkable water-based wood adhesive comprised of a critical mixture of from 0.10 to 0.75 by weight of a water-soluble, high-viscosity thickening age nt polymer such as hydroxyethylcellulose, 0.05 - 0.40% by weight of a defoamer to dissipate foam quickly during manufacture, 25.00 to 45.00% by weight of solids o f a self-cross-linking polyvinyl acetate polymer (treated with N-methylolacrylamid e) dispersed in water, the polymer having a molecular weight of about 30,000 to abo ut 300,000, 1.00 - 3.00% by weight of a plasticizer/coalescing agent such as 2,2, 4-trimethyl-1,3 pentanediol monoisobutyrate, 0.50 to 1.00% of an acidic catalyst , such as aluminum chloride, 4.00 to 12% by weight of fine particle-size wood fibers (s oft or hard wood fibers or a mixture of both) and 0.10% by weight of a preservative. The viscosity of this adhesive gel will "break-down" when its container, e.g. a squeeze-bottle or flexible tube is finger-pressed resulting in a sufficiently lo w viscosity to allow for easy extrusion from the small orifices, approximately 0.1 0 inch diameter or a rectangular slit opening such as approximately 1/16" wide by 5/16" long of the adhesive application tips attached to such squeeze-bottles and flexi ble tubes. When pressure is released after the desired amount of adhesive flows out of the container, the adhesive quickly reverts very closely to its original gel sta te so that it will not "run" on vertical surfaces nor "spill" when used as a general purpos e wood adhesive. This adhesive has sufficient wet tack to hold two pieces of wood together while still allowing repositioning of the pieces of wood before drying. In addition, since this product contains real wood fibers, its dry film is stainabl e and easy to sand.

摘要： Method of producing dry polyvinyl acetate particles that are readily dispersible in water, are vinyl acetate substantially monomer-free and are useful for making polyvinyl ace tate dispersion compositions that are low in odor, form clear dried films and may be used in adh esives, 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 co nverting 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 th at is substantially free of vinyl acetate monomer.

摘要： A thixotropic adhesive gel comprises a self-crosslinking copolymer of polyvinyl acetate and N-methylol acrylamide and a cellulose fibre filler. Also claimed are (i) a process of preparing such a gel comprising mixing (wt.%): (A) a water-soluble, high viscosity thickening agent (0.10-75); (B) a defoamer (0.05-0.40); (C) a vinyl acetate/N-methylolacrylamide copolymer, dispersed in water (25.00-45.00 solids); (D) a plasticiser/coalescing agent (1.00-3.00); (E) an acidic catalyst (0.50-1.00); (F) fine particle-size cellulosic fibres (4.00-12.00); and (G) a preservative (0.10); and (ii) an adhesive gel compsn. comprising a crosslinkable polyvinylacetate copolymer, cellulosic fibre filler and thickening agent, the gel having a thixotropic index of 1.5-7. Pref. the copolymer is crosslinked through the action of an acidic metal crosslinking catalyst; the compsn. further comprises a water-soluble high viscosity thickener, a plasticiser/coalescing agent, a defoamer, and a preservative. The gel produced pref. has viscosity no greater than 90000 cP one month after prepn.; and the cellulose fibres are pref. wood fibres of particle size 2000mu . The water soluble high viscosity thickening agent is hydroxyethylcellulose; the plasticiser/coalescing agent is 2,2,4-trimethyl- 1,3-pentanediol monoisobutyrate; the acidic catalyst is AlCl3; and the cellulosic fibres are from soft and/or hard wood fibres, forming an adhesive gel having a viscosity as prepd. (Brookfield RVF, no.6 spindle at 25[deg]C) at 2 rpm of 30500-47000 cP and at 20 rpm 14500-25500 cP.
