Abstract:
Apparatus and process for continuous surface preparation of metal materials. The metal material is grit blasted with a mixture of fine particles of aluminum oxide in air and water. The metal material is rinsed with water to remove the grit. The metal material is subjected to a caustic solution of sodium hydroxide and then rinsed with water to remove the caustic solution of sodium hydroxide. A sol-gel coating is applied to the metal material and the water portion of the sol-gel coating is evaporated. A liquid adhesive coating is applied to the sol-gel coating on the metal material and the solvent portion of the adhesive coating is evaporated.
Abstract:
Disclosed is a pressure-sensitive adhesive sheet for use in processing a product such a semiconductor wafer. To provide a pressure-sensitive adhesive sheet that provides a minimized number of broken semiconductor wafers during the process of polishing them and that produces a less curl of the wafer due to the residual stress of the pressure-sensitive adhesive sheet, the pressure-sensitive adhesive sheet includes a composite film formed from a composition containing a urethane polymer and a vinyl polymer as effective components, a first film comprising a material different from that of the composite film, and a pressure-sensitive adhesive layer, in which the pressure-sensitive adhesive sheet has a modulus of 9 N/mm2 or more and 250 N/mm2 or less when an oblong piece of the pressure-sensitive adhesive sheet with a width of 20 mm is bent at a radius of curvature of 3.0 mm.

Abstract:
The present invention provides an apparatus for applying thermoplastic marking material to a pavement surface. The apparatus includes a hopper for holding a supply of particulate thermoplastic marking material in a non-molten state, a means for conveying the thermoplastic marking material from the hopper to a continuous melt processor, and a conduit from the continuous melt processor to a dispenser that directs molten thermoplastic marking material to the pavement surface. The apparatus further includes means for heating the continuous melt processor and conduit to a temperature that is higher than the melt temperature of the thermoplastic marking material. The present invention also provides a method of applying a thermoplastic marking material to a pavement surface. The method includes conveying a stream of particulate thermoplastic marking material stored in a non-molten state in a hopper to a heated continuous melt processor in communication with the hopper, wherein the stream of thermoplastic marking material exits the continuous melt processor in a molten state, and pumping the stream of molten thermoplastic marking material through a heated conduit from the continuous melt processor to a dispenser that directs the molten thermoplastic marking material to the pavement surface.
Abstract:
A packaging material, a method of making such a material, and a package made from such material, are disclosed. A substrate comprises at least one sheet of plastic material. An energy-curable coating is applied to one side of the substrate, which will be the outside of the eventual package. The energy-curable coating is cured by exposing it to an electron beam or other appropriate energy. A cold-seal cohesive coating is applied to the other side of the substrate. The package is formed by pressing together portions of the inside surface of at least one sheet of the material having the cold-seal cohesive coating on them to form a seal. Preferably, the cold-seal cohesive coating is applied only to those portions of the material that are to form seams in the eventual package.
Abstract:
The present invention provides a cyanoacrylate adhesive composition having high shear bond strength, peeling bond strength, tensile strength and impact bond strength and superior wear characteristics particularly in toy applications where hostile play environments demand hot-cold cycle resistance. The cyanoacrylate adhesive composition contains (a) up to 20% by weight of a cyanoacrylate monomer, (b) a styrene-based elastomeric block copolymer, and (c) a specific solvent which is selected to effect the solution of both components. The invention is also directed to a method of applying the instant adhesives to substrate surfaces.
Abstract:
A color agent for a road marking material comprising composite particles having an average particle diameter of 0.01 to 10.0 nullm, said composite particles comprising: inorganic particles; a gluing agent coating layer formed on surface of said inorganic particle; and an organic pigment coat formed onto said gluing agent coating layer in an amount of from 1 to 500 parts by weight based on 100 parts by weight of said inorganic particles. The color agent for a road marking material, contains no harmful elements and exhibits excellent tinting strength, hiding power, light resistance and heat resistance, and is suppressed in surface activity thereof. The road marking material using the color agent, shows a less change in hue with the passage of time and an excellent retroreflective property.
Abstract:
An apparatus and method are provided for applying adhesive to an outer circumference of a section of tubing. The apparatus includes opposed grippers with concave adhesive transfer areas that can be moved into surrounding relationship with the tubing. Adhesive dispensing passages communicate with the adhesive transfer areas for delivering adhesive to the tubing. Counterbores are at opposed ends of the adhesive transfer areas and communicate with a vacuum source for removing excess adhesive.
