Abstract: Coating compositions include polymeric particles, an isocyanate-containing crosslinking agent, and water. The polymeric particles include at least one incorporated monoalkenyl aromatic monomer, at least one incorporated vinyl-containing surfactant macromonomer, and at least one incorporated acrylic monomer. At least one incorporated acrylic monomer in the polymeric particles includes a hydroxyl, amine, or a carboxylic acid functional group. The crosslinking agent is an isocyanate-containing organic compound or such a compound with blocked isocyanate groups. Coating compositions may be deposited and cured by heating to form crosslinked coating compositions. Such crosslinked coating compositions exhibit excellent solvent resistance.

Abstract: A process is disclosed for a continuous, high temperature polymerization process for preparing a free radically polymerized epoxy-functional polymeric product. The process comprises continuously charging into a reactor at least one epoxy-functional acrylic monomer, and optionally at least one non-functional free radical polymerizable monomer. An optional free radical polymerization initiator may also be added. The reactor is maintained at an effective temperature for an effective period of time to cause polymerization of the monomers into a polymeric product, such that the polymeric product is formed substantially free of gel particles. A clear coating is also disclosed incorporating polymers of the present invention, such that the clear coating has a low Delta b value at standard conditions.

Abstract: Discrete non-clumping mechanically stable geometric alloyed material shapes having about 55-95% by weight thermoplastic elastomer and about 5-45% thermoplastic polymer and about 0-12% by weight filler are used for removing organic contaminates from contaminated fluids. The shapes are typically spheres having a maximum dimension of 0.125 inches, or circular discs having a thickness of less than 6 millimeters. The shapes are put in a loose form or packing, and a fluid containing organic contaminants (such as water, air, or a soil slurry) is brought into contact with the shapes so that the shapes absorb organic contaminants from the fluid, typically absorbing more than 90% of the contaminants in the first pass through. The contaminated fluid is typically passed through an ozone generator before being brought into contact with the shapes. The shapes may be foamed, e.g. utilizing about 0.1-10% by weight foaming agent.

Abstract: The present invention improves the concentricity after expansion process of a heat shrinkable tube which is required to have a thin wall and hardness, and further aims to obtain elongation of 100% or more in a heat aging test, copper stability test, and heat shock test. The heat shrinkable tube satisfying such aim uses a medium- or high-density polyethylene that has a molecular weight distribution (Mw/Mn) of 30 to 55, an MFR of 0.05 to 0.2, and a specific gravity of 0.94 to 0.96. A medium- or high-density polyethylene obtained by combining an ethylene-vinyl acetate copolymer, ethylene-ethylacrylate copolymer, ethylene-methylacrylate copolymer, and ethylene-ethylmethacrylate copolymer may be used. More preferably, for an antioxidant, phenol-based and sulfur-based antioxidants are used together and zinc oxide is added.

Abstract: Semiconductor circuit devices (dies) are incorporated into moisture-impenetrable electronic packages by forming enclosures around the die in three separate parts—base, sidewalls, and lid. The die is first soldered or otherwise bonded to the base, followed by attachment of the sidewalls to the base, and finally the lid to the sidewalls. For procedures involving a heat-conductive base and a high soldering temperature, the die can be secured to the base at the high soldering temperature, followed by application of the sidewalls to the base at a significantly lower temperature, avoiding potential high-temperature damage to the sidewalls. Plastic sidewalls which would otherwise deteriorate or become distorted upon exposure to the high soldering temperature can thus be used.

Abstract: A binding metal for covering an object with a heat-shrinkable sheet and holding the heat-shrinkable sheet in a state in which both end portions of the sheet face each other. The binding metal has two long members holding the heat-shrinkable sheet, and these long members have an opening and closing portion at one end portion such that when the long members are substantially parallel, the distance between the long members at the opening and closing portion is wider than that of the intermediate portion, and a clamping force is applied to the heat-shrinkable sheet by closing the opening and closing portion. By forming to the binding metal a deformed portion of a form fitting an irregular portion of an object to be covered, the object can be covered with a heat-shrinkable sheet without forming a gap.

The composition comprises (a) a thermoplastic polyolefinic resin having a density of smaller than 0.89 g/cm3, which is prepared by copolymerizing ethylene and a non-polar &agr;-olefin in the presence of a single-site metallocene catalyst, (b) a halogen-containing flame retardant, and (c) zinc oxide. After crosslinking, the composition is used in forming an insulating coating for insulated wires and shielded wires, and in forming insulating tubes.

The pair of inner legs cooperate to define at least in part an elongated channel therebetween having opposing inner surfaces adapted to receive the insertion rib. Each of the inner legs has, at a lower portion thereof, a retainer adapted to be received within the retention slot.

As a result, random charging between the components of the mixture is reduced and controlled, and predictable charging is achieved.

Abstract: A method of preparing fiber reinforced acrylic thickened compositions which can be molded under low pressures and temperatures to provide thermoset articles, wherein liquid reactive components are slowly absorbed in high molecular weight solid acrylic resin in the form of large particles. The acrylic resin functions as a thickener which delays the viscosity build allowing fiber reinforcement to be incorporated before molding. The molding composition is well suited for use in dentistry and other fields where small amounts or molding composition are used occasionally.

Abstract: A composition and method that provides a chemically grafted coating onto a substrate. The composition comprises an acrylate and a grafting initiator. The acrylate may be a waterborne urethane acrylate. The composition may also comprise resistance agents, adhesion agents, UV curing photoinitators, defoaming agents, and/or deglossing agents. The substrate may be any wood or plastic, but works well with heat shrinkable polyolefin tubing. The composition may also be quick curing such that the coating from the composition may be cured under a D bulb and an H bulb at a rate of 100-160 feet/minute. The coating on the substrate resists delamination and wear. The coating may have indicia printed on the coating, the indicia being composed from ink or other printable materials.

Abstract: At a crossing, rubber interface strips are positioned between the rails and the asphalt or concrete. A U-shaped spring-clip fits underneath the rail, and has upstanding arms that carry tappets, which engage the strips. One of the arms is threaded, and carries a screwed tappet-rod. Turning the tappet-rod closes the distance between the tappets, clamping the strips onto the sides of the rail, and forcing the springy arms apart. The spring-clips are manipulated into position while in an unstressed condition. The spring-clip is only brought up to force when finally assembled. Assembly can be done without tools, and with little danger of mis-assembly, or of injury to workers.

Abstract: Latex formulations which exhibit a reduced amount of yellowing when exposed to heat, aldehydes or ultraviolet light contain polyfunctional amines, reducing agents, and/or reduced levels of styrene.

Abstract: A differential density alteration (DDA) device to enable the separation and partitioning of particles of one or more selected members of plastics included in a mixture of a plurality of different plastics in which each member of the plurality of different plastics is divided into discrete particles. The DDA device heats the mixture to a temperature for a time that causes the particles of the one or more selected members to alter in such a way that the difference between the apparent density of the particles of the selected one or more members and the apparent density of particles of the other members of the mixture (the differential density), after heating, is different from the differential density before heating, whereby the alteration in differential density produces a differential density alteration (DDA).
