Abstract: Upholstery material and shoe upper material made from a base sheet of criss-crossing elastomeric polyurethane fibers running parallel to the surfaces of the sheet, said fibers being bonded together at their points of contact. In one preferred form the product has a preformed skin whose thickness is less than about 100 microns and preferably less than about 50 microns, such as about 20 to 40 microns and the skin is joined to the fibers of the base sheet by spaced fingers of a binder.

Abstract: A solution of elastomeric polyurethane in a volatile solvent is centrifugally sprayed onto a base in a strong electrostatic field to form long fibers that are swept across the base and deposited thereon in generally straight condition, overlapping and adhered to previously deposited fibers. Novel fibrous sheets of high strength are thus produced. The intersecting fibers may be ribbon-like.

Abstract: Room-temperature-curable silicon-terminated organic sealant compositions having improved cure speeds, and metal and glass primer compositions for use therewith. These sealant compositions comprise a blend of a small amount of N-beta-aminoethyl, gamma - aminopropyl trimethoxy silane with an organosilicon-capped, isocyanate-terminated polyurethane polymer. The composition further comprises a carbon black filler containing less than 0.05% of water and preferably further comprises a moisture-curing catalyst such as dibutyl tin diacetate.

Abstract: A process for making a smooth perforated contoured resilient panel of a type suitable for use as a decorative headliner in the passenger compartment of vehicles or the like. A thermoplastic composite laminar sheet comprising a pair of films tenaciously bonded to the opposed faces of an intervening thermoplastic foam core having closed cells containing air and residual blowing agent is perforated in flat sheet form whereafter it is heated to an elevated temperature to effect heat softening and expansion of the foam core resulting in localized dimpled recesses in the faces adjacent to the apertures or perforations. The heated expanded sheet is thereafter thermoformed between appropriately contoured mold surfaces to effect a contouring and compaction of the sheet to a thickness substantially equal to or less than the thickness of the dimpled or recessed sections forming a contoured sheet having substantially smooth exterior surfaces.

Abstract: A novel coating composition useful in automobile refinish air-dry paint coating compositions. The novel coating composition comprises a blend of a maleic modified acrylic copolymer and an unsaturated polyether.

The sealants exhibit superior adhesion to glass, aluminum and steel.

Abstract: A water-reducible acrylic enamel coating composition capable of being substantially completely cured at a relatively low temperature, such as about 250.degree. F. and containing a water-miscible partially etherified melamine formaldehyde cross-linking agent and an acrylic copolymerization product of about 3% to about 8% of an unsaturated carboxylic acid, about 10% to 30% of a hydroxy functional monomer and about 62% to 87% of a nonfunctional monomer. The acrylic copolymer is further characterized as having a glass transition temperature of about -10.degree. C. to 45.degree. C. and a molecular weight of about 2,000 to about 100,000. The aminoplast resin preferably is only partially etherified and contains about 10% to about 30% by weight reactive methylol groups.

Abstract: An apparatus and method for the spray application of solvent-thinned coating compositions whereby optimum coverage of a substrate with a liquid film is consistently achieved without incurring sagging, run-off or surface irregularities, such as orange peeling, in spite of wide fluctuations in the temperature and/or humidity of the surrounding atmospheric environment. In accordance with the invention, a shroud is provided which is disposed in encompassing relationship around the spray nozzle to which air is supplied at a controlled temperature and/or humidity which envelopes and becomes entrained in the spray forming a controlled localized atmosphere and achieving a controlled vaporization of solvent from the liquid droplets during the course of their travel from the nozzle to the surface of the substrate being coated.

Abstract: An artificial leather sheet material, comprising a layer of permeable fabric made of interlaced multifiber yarns, the lower face of said fabric having an open nap of fibers teased from said yarns and bonded together, and a continuous layer of polymer material on the upper face of said fabric. The bonded nap may be subjected to spaced short cuts to give it a rough appearance.

Abstract: Pigmented non-aqueous dispersed polymer compositions containing melamine-formaldehyde resin are disclosed. The dispersed polymer and the soluble stabilizer polymer are both cross-linkable with the malamine resin to give improved thermosetting paints, especially for metal surfaces such as automobile bodies.

Abstract: A napped fabric is treated to bond the nap fibers together while leaving the nap structure largely open and porous.The surface of the bonded nap is then subjected to a series of spaced short cuts to form spaced clumps of bonded fibers which clumps have free ends projecting from the bonded nap so that they can be brushed from stable upright positions to bent-over positions, giving an attractive rough appearance resembling a split suede leather.

Abstract: Pigments are dispersed in fiber grade polyester by a two-step process:A. pigment and polyethylene are mixed at 50 to 75% pigment concentration under intensive mixing conditions, andB. the concentrate in (a) is reduced with fiber grade polyester under additional mixing conditions without substantial degradation of the polyester.

Abstract: Aqueous coating compositions containing dissolved reactive acrylic copolymers and aminoplast resins are disclosed. The pigmented coatings are especially useful for topcoat enamels for automobiles. A method for applying coatings to automobiles is also disclosed comprising spraying the coating composition in a relative humidity of 40 to 60% followed by heating the wet coated surface to remove the volatile components and then heating to cure the coating.

Abstract: Thermosetting coatings comprising multiple coats of thermosetting organic coating material, including a top coat of powder paint, are cured by employing a single baking step.

Abstract: Liquid colorant dispersions preferably comprising 5-70 weight percent colorant and 95-30% vehicle. The colorant is preferably a conventional pigment. The vehicle typically comprises two major components, (1) from 5 to 25 weight percent of a physically active, chemically inert solid in the form of fine particles (less than 90 microns in size), and, correspondingly, (2) from 95 to 75% of a surfactant system. It is often desirable to also include in the vehicle materials which serve as extenders and/or which modify vehicle properties such as rheology. Many times such materials are conventionally known as plasticizers although they do not function as such when used in the dispersions of this invention. The inert solid is preferably calcium carbonate. The preferred surfactant system is a sorbitan ester surfactant, such as sorbitan trioleate.
