Abstract: The present invention is directed to a method of coating a substrate under ambient conditions by conventional single step application means, such as single spray heads with a single pack fast dry paint, containing a coating composition of the present invention, which contains a latex binder, an associative thickener and a water soluble organic volatile solvent. The amounts the associative thickener and the solvent are such that the paint has an in-can viscosity under ambient conditions in the range of from 1,000 cps to 6,000 cps and a set-to-touch dry time rating under ASTM D-1640 of less than 10 minutes. The method of the present invention and coating composition used therein can be used to produce a quick drying coating useful as, a pavement or road marking traffic paint for concrete, asphalt or bituminous roads, walkways, or parking lots.

Abstract: A method for forming a coating film by sequentially forming a pigmented base coat and a clear top coat on a substrate. The pigmented base coat composition includes (1) an OH-containing resin, (2) an amino resin, (3) a polyorganosiloxane resin a number average molecule weight of at least 1,000 and having at least two groups per molecule selected from a silanol group and an alkoxysilane group and (4) a flaky metal or a mica powder in (5) an organic solvent. The clear top coat composition includes (1) an OH- and epoxy-containing base resin which additionally contains at least one of a silanol group and a hydrolyzable group bound directly to a silicon atom, (2) a curing catalyst and (3) an organic solvent.

Abstract: A method produces a surface of a cured silicone elastomer with a hardened protective coating when an RTV silicone composition is blended with an oxygen curing compound, exposing the resulting composition to moisture to produce a cured dull surface, then applying a hardenable protective coating composition (such as paint) to the cured surface to obtain a flaw-free film, and then allowing the coating composition to harden.

Abstract: A process and apparatus for treating cellulosic fiber containing fabrics to improve durable press and shrinkage resistance includes using steam as a vehicle to supply vaporized liquid cellulosic cross-linking agent and vaporized liquid catalyst to a reaction chamber in which the fabric articles are treated by cross-linking the cellulose. Normally liquid cross-linking agent and liquid catalysts are directly injected into a stream of treating steam to cause vaporization of the cross-linking agent and catalyst. Alternatively, a steam driven ejector type pump is utilized to entrain and vaporize liquid cross-linking agent and liquid catalyst in a flowing stream of steam supplied to the reaction chamber. Gaseous ammonia may also be supplied to the reaction chamber to condition the cellulosic material containing fabric before cross-linking.

Abstract: A wood product is protectively coated while maintaining the appearance of wood without discoloration by applying to the surface of a dry wood member a sealer coating containing a cyclic epoxy and an anhydride and curing the sealer, while reacting, at least a portion of the epoxy with lignin in the wood and at least a portion of the anhydride with cellulose and lignin in the wood, to bind the sealer to the wood, and cross linking cellulose, followed by applying a protective coating over the sealer before the sealer has been cured completely to bind the protective coating to the sealer. The protective coating provides a barrier to UV penetration and increases the durability of the surface.

Abstract: A composition is provided which, when applied to a metal surface, forms a corrosion-inhibiting film thereon. The composition comprises an epoxy resin, an effective amount of a curing agent for the epoxy resin, an alcohol, and a hydrocarbon diluent. The composition is applied by contacting the metal surface with the composition as one solution or as a hydrocarbon solution of the epoxy resin and a solution comprising the alcohol and the curing agent. The composition is particularly useful in the treatment of down-well metal surface in oil and gas wells to inhibit the corrosion of the metal.

Abstract: A microtiter plate containing a plurality of reaction wells for conducting immunogenic reactions the bottom wall of the reaction well has an inner surface which is substantially hydrophilic, and the side wall of the reaction well has an inner surface which is substantially hydrophobic and a process for producing said trays.

Abstract: A process for the manufacture of a decorative product particularly for use in the ornamental field, in which selected organic chemical compounds are employed, which are prepared and applied in a way to confer to the same product favorable safety characteristics during use.

Abstract: The invention relates to an anti-adhesive polyester film comprising polyester film support base having a semicrystalline orientation, which comprises, on at least its surface designed to receive the liquid mass, a coating comprising a fluorine-containing polymer. This application also relates to a method of forming a polyurethane layer onto an adhesive layer and the resulting polyurethane layer.

Abstract: A method is disclosed for impregnating fibre bundles with molten or liquid resin (24, 29) in manufacturing a fibre-reinforced material, which material comprises fibre bundle or bundled groups of fibres, wherein each fibre is surrounded by matrix resin, by impregnating a continuous web (10, 10a) of one or more fibre bundles with molten or liquid resin (24, 29) and solidifying said resin by cooling or chemical reaction. Before said impregnation the molten or liquid resin material (29) is made subject to shear forces by bringing it to flow between two closely nearby surfaces (26, 27) which are in moving relationship into each other.

Abstract: Lecithin is coated onto the surface of plastics such as polystyrene and polyethylene to enhance the wettability of aqueous liquids to the plastic. In one application, plastic test wells are coated with lecithin to enhance the ability of liquids placed into a well with sloping sides to flow in a regular manner into a well with vertical sides. The lecithin is applied to the plastic by dissolving the lecithin in an organic solvent such as heptane, coating the solution onto the plastic surface, and evaporating the solvent.

Abstract: Use of a water-dispersible polymer as binder in an aqueous filler composition which may or may not comprise, in addition to other polymeric binders, crosslinking agents and the customary additives, wherein the water-dispersible polymer is a polyurethane resin which contains building blocks derived from(A) polyisocyanates,(B) polyols having an average molecular weight M.sub.n of at least 400,(C) low-molecular polyols if desired and,(D) compounds containing at least two groups reactive toward isocyanate groups and at least one group capable of forming anions, and(E) compounds which are monofunctional or contain active hydrogen of variable reactivity, these building blocks being always positioned at the chain end fo the polyurethane resin, and optionally(F) compounds which are other than (B), (C), (D) and (E) and contain at least two groups reactive toward NCO groups.
