Abstract: A method of attaching to a rubber molded part a strip having an acrylic polymer adhesive on one side, including the step of applying radio frequency energy to the rubber molded part to generate heat therein and to cause the acrylic polymer adhesive to melt bond to the rubber molded part. The acrylic polymer is an acrylic-silane interpolymer of primarily acrylic ester monomer interacted with an organosilane, which interpolymer has a Tg of −10° to 80° C. The rubber molded part includes radio frequency sensitive material to facilitate bonding to the acrylic polymer adhesive during application of the radio frequency energy thereto. Desirably, the strip also includes a pressure sensitive adhesive on its other side for securing the rubber part to a component of an automobile or other vehicle by applying pressure to the rubber part. The strip may include an acrylic foam core between the acrylic polymer adhesive and the pressure sensitive adhesive.

Abstract: Anti-static cleanroom products having a coating of conductive polymeric particulates which decreases the surface resistivity of the products. Preferably, the particulates are pyrrole polymers. The anti-static properties are achieved by depositing conductive polymer particles onto the non-conductive substrate surface. The anti-static products include cleanroom wipers, stationery products (notebooks and writing instruments), garments and swabs (polyurethane foam tipped). The cleanroom stationery products include notebooks comprising polyethylene impregnated with silica. The invention also includes anti-static plastic gloves.

Abstract: This invention provides reinforced, water-resistant membranes, and methods of manufacturing and installing such membranes. These membranes include a mastic layer having first and second major surfaces and a fiber-containing reinforcing layer disposed within the mastic layer for improving the mechanical strength of the membrane. The membrane can be bonded to an underlying substrate by the application of heat or pressure to form an adherent bond. The reinforced membrane of this invention can have a tensile strength of at least about 300 psi or more.

Abstract: An electrically poorly conductive material for producing external glow-discharge protection for an electrical conductor, includes a base material which is provided with a conductive coating on at least one side. In order to ensure adequate external glow-discharge protection and cost-effective production of an insulating sleeve, even for high rated voltages, the conductive coating is produced essentially from carbon, which has microcrystalline and amorphous structures.

Abstract: The invention provides gel-coated materials that provide enhanced flame-, physical- and chemical-resistance to the foamed materials. The gel coatings can be created with a sol-gel process. Such treated materials can be used, for example, in the manufacture of articles of clothing that are to be used in environments in which fire and exposure to acids, bases or other chemicals which tend to corrode foamed materials is a potential hazard.

Abstract: An on-machine-seamable papermakers' fabric includes a first and a second base fabric, each of which is joined into endless form with a seam. The first and second base fabrics are attached to one another by at least one layer of staple fiber batt entangled therethrough such that they are offset with respect to one another in a lengthwise direction when so joined. As a consequence, seaming loops at one widthwise edge of the first base fabric coincide with a non-seam region of the second base fabric, and seaming loops at one widthwise edge of the second base fabric coincide with a non-seam region of the first base fabric. These coincident non-seam regions have additional flow-resistant material included so that when the on-machine-seamable papermakers' fabric is joined into endless form by closing both seams, it may, in the vicinities of the seams, have permeabilities to air and water substantially identical to the remainder of the fabric body thereof.

Abstract: A fabric, which can be used more especially as a pierce-proof fabric but also as a decorative fabric, includes a plurality of interconnected scales, which have bores to connect them to one another, and into which connecting members extend. The connecting members are directly formed on the scales. Because the scales overlap one another in the manner of roof tiles (form an imbrication) and because, in order to make a flat connection, the scale itself in the fabric overlaps at least two adjacent scales and is overlapped by at least two additional adjacent scales, the fabric can also meet increased safety requirements in an advantageous manner.

Abstract: This invention relates to metallized, particularly aluminized, fabrics which are coated with specific polyurethane finishes and primer coatings comprising novel phosphate-containing primers. Such specific polyurethanes are cross-linked when reacted with the primer coatings and applied in latex form. Upon impregnation within metal-coated fabrics, these particular polyurethanes encapsulate the metal particles and provide vastly improved washfastness properties to the fabrics and thus ensure the retention of substantially all the metal coating within and on the target fabric. The phosphate-containing primer provides remarkably improved adhesion between the metal and the polyurethane for excellent durability and washfastness. The primer compositions as well as the methods of producing a metallized coated with a primed polyurethane encapsulant are also provided.

Abstract: A diaper construction is provided with an external porous reinforcement strip at the front part of the outside of the diaper, which strip provides reinforcement against an adhesive fastening tab and provides an oil contamination tolerant adhesion surface.

Abstract: The process and apparatus of the present invention involves treating a well-integrated woven or non-woven web of hydrophobic fibers to make selected areas hydrophilic. It also can be used to make a web of hydrophilic fibers selectively hydrophobic. It uses a plurality of selectively adjustable covers on an applicator roll rotating in a bath of liquid to place the liquid material on selected areas of the web as the web moves over the roll. In a preferred embodiment the web is non-woven and the fibers are hydrophobic in nature, e.g., dry-laid or melt-blown polypropylene or polyethylene fibers or spun-bonded hydrophobic filaments. A woven web made of cotton or other hydrophilic fibers may also be used if the end result is to create partially hydrophobic areas on a hydrophilic web. The areas of liquid are positioned on the web only where desired so as to eliminate the excessive cost of unwanted and unnecessary coating material. If the web is hydrophobic, the liquid makes that area hydrophilic.

Abstract: A cover tape for chip transportation stuck to a surface of a carrier tape which has parts for accommodating chips formed intermittently in its lengthwise direction, to thereby seal the chip accommodating parts, wherein said cover tape comprises a tape-shaped substrate and pressure sensitive adhesive parts superimposed on one side of the tape-shaped substrate so that the pressure sensitive adhesive parts do not face the chip accommodating parts, the above pressure sensitive adhesive parts comprising a silicone pressure sensitive adhesive and a crosslinking agent (C) capable of crosslinking therewith, the above silicone pressure sensitive adhesive comprising: (A) a silicone resin component and (B) a silicone rubber component which contains a phenyl group. This cover tape for chip transportation enables avoiding a lifting/separation of cover tape from carrier tape caused by a difference in thermal shrinkage ratio when a polystyrene carrier tape is used.
