  • Patent number: 7928282
    Abstract: The present invention provides a substrate treated with an linked enzyme. It has been discovered that a substrate treated with a linked enzyme can be effective in improving the ability of the substrate to absorb viscoelastic materials, such as menses, by cleaving a protein structure present in some viscoelastic materials. In addition, the linked enzyme is less likely to migrate from the treated material onto the user, as compare to an enzyme being placed directly on the substrate, thereby reducing the risk of sensitization to the user of the absorbent product. Also provided by the present invention are absorbent articles which contain at least one surface or layer containing the linked enzyme.

    Abstract: A roofing underlayment comprises a reinforcing layer, which is extrusion coated on at least one side with an anti-slip coating layer. Preferably, the reinforcing layer comprises a woven polyethylene or polypropylene scrim. The anti-slip coating layer comprises a compound based on a styrene and ethylene/butylene-styrene, S-E/B-S, block copolymer, such as the compound sold under the trademark KRATON® MD6649. The anti-slip coating layer is low in cost and helps prevent water from penetrating the primary roofing material. In addition, the anti-slip coating layer provides an improved anti-skid surface upon which an individual may safely walk.

  • Publication number: 20100151757
    Abstract: The present invention provides glass fiber fabric reinforcements, cement boards, and glass fiber coatings for such reinforcements. The glass fiber fabric reinforcement includes a glass fabric containing multiple yarns containing glass filaments and a polymeric coating disposed onto the multiple yarns to form a coated glass fabric. The polymeric coating comprises a polyolefin based copolymer composition whereby the glass fabric has a Gurley Stiffness measurement of about 100-3000 mg and an ASTM D 638 (2% Secant) modulus of compression of about 1-100 MPa. The reinforcement is sufficiently drapable and lacking in shape memory so as to be curved around the edge of a cement board during the manufacture of same.

  • Patent number: 7709404
    Abstract: The invention concerns a process for making a scrim-reinforced prepreg for use in building low-porosity lay-ups, characterized in that a conventional prepreg is formed of a fibrous reinforcement and a heat-curable resin, the prepreg having suitable viscosity and sufficient tackiness to hold a scrim which is adhered to the prepreg by applying light pressure, so that the scrim is impressed onto the prepreg to such a degree, that less than half of the circumference of the scrim strands becomes coated by the prepreg-resin.

  • Patent number: 7625827
    Abstract: A corrosion-resistant lath is provided for use in exterior finishing systems, such as stucco systems and exterior insulation and finish systems (“EIFS”). The lath includes in a first embodiment an open, woven fabric comprising weft and warp yarns containing non-metallic fibers, such as glass fibers. A portion of the weft yarns are undulated, resulting in an increased thickness for the fabric. The fabric is coated with a polymeric resin for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making an exterior finish system and building wall including an exterior finish system using such a lath.
