Patent number: 6472469Abstract: Using urea extended phenolic binders with a resin to urea solids ratio below 60/40 can significantly reduce production costs in the manufacture of fiberglass products without adversely affecting product performance or producing formaldehyde or ammonia emissions at unacceptable levels.

Patent number: 6132549Abstract: Discloses compositions of urea dissolved in aqueous, polymerizable phenolic resole resins, wood-product laminated composite products produced with such resins, with or without the urea, and methods for the production of wood-product laminated composites with such resins. The resins contain the alkaline polymerization product of (a) formaldehyde polymerized with phenol and aliphatic hydrocarbylphenol or (b) aliphatic hydrocarbylphenol dissolved in the resin containing the polymerization product of phenol and formaldehyde, wherein the hydrocarbylphenol has from 9 to 17 carbon atoms in the hydrocarbyl group and the quantity of hydrocarbylphenol is from about 0.2% to 5% based on the weight of the aqueous resole resin. Wood-product laminate composites bound with the above resole resin, after curing, exhibit unexpectedly low water absorption, good internal bond strength and reduced thickness swell properties.Type: GrantFiled: September 22, 1998Date of Patent: October 17, 2000Assignee: Borden Chemical, Inc.Inventors: Gregory F. Nieckarz, Fred E. Carlson, William D. Detlefsen

Patent number: 6130289Abstract: An aqueous phenolic resin dispersion that includes an aqueous continuous phase and, dispersed within the aqueous phase, the reaction product of a phenolic resin precursor and a modifying agent wherein the modifying agent includes at least one ionic group and at least one functional moiety that enables the modifying agent to undergo condensation with the phenolic resin precursor. The resulting dispersed phenolic resin reaction product includes at least one phenolic ring to which is bound the ionic group from the modifying agent. The pendant ionic group is a sulfate, sulfonate, sulfinate, sulfenate or oxysulfonate and the reaction-enabling moiety preferably is a hydroxy or hydroxyalkyl.Type: GrantFiled: January 22, 1999Date of Patent: October 10, 2000Assignee: Lord CorporationInventor: Helmut W. Kucera

Patent number: 6054527Abstract: A single adhesive composition for use in bonding more than one class of rubber polymer to textiles, in particular nylon and polyester fabric. The composition comprises an aqueous mixture of: a) about 85 to about 90 weight % polychloroprene latex; b) about 2 to about 6 weight % of at least one prepolymer of resorcinol with formaldehyde; c) about 4 to about 8% by weight of at least one blocked diisocyanate compound; and d) sufficient water to adjust the solids content of the mixture to about 15 to about 40% by weight; wherein the percentage of solids add-on on fabric treated with the composition ranges between about 5 and about 20% based on the weight of the untreated fabric. The preferred blocked diisocyanate compound is caprolactam blocked methylene-bis-(4-phenylisocyanate). The end-products that are contemplated for the present invention include, but are not limited to, diaphragms, molded articles, V-belt covers, conveyor belts, bead wraps for tires, hose wrap, dodge couplings and the like.Type: GrantFiled: December 27, 1996Date of Patent: April 25, 2000Inventors: Gary D.

Patent number: 5929134Abstract: An ink composition suitable for ink jet printing operations comprising an aqueous resin dispersion and an aqueous colorant where said ink composition is substantially free of volatile organic compounds. Compositions are provided that form printed images that, without curing, are solvent-washable with isopropanol, ethanol, water, and mixtures thereof, and are retortable, without curing. Ink jet compositions capable of forming colored images capable of being washed with isopropanol, ethanol, water, and mixtures thereof, after curing, are also provided. Finally, ink jet inks capable of withstanding washing with strong organic solvents, such as methylethylketone and methanol, after curing, are also provided.Type: GrantFiled: June 7, 1995Date of Patent: July 27, 1999Assignee: Videojet Systems International, Inc.Inventors: Bruce A. Lent, Adrian M. Loria
