  • Publication number: 20140194020
    Abstract: A glass mat includes an assembly of glass fibers, a binder composition and an asphaltic coating. The binder composition includes an organic resin and an adhesion promoter. The glass mat has an at least 2% increase in tear strength as measured using the methods specified in ASTM D3462, compared to an asphaltic coated glass mat having a binder composition without the adhesion promoter. Further provided is an asphalt roofing product including the glass mat and a method of increasing tear strength in an asphalt roofing product.

  • Publication number: 20130014445
    Abstract: Abrasive aggregates and fixed abrasive articles comprising formaldehyde-free polymer binder and a plurality of abrasive grains are provided that are particularly suitable for machining operations, in which abrasion is carried out to remove material and improve surface quality. Certain embodiments combine an abrasive grain, which can be in the form of microparticles, and a formaldehyde-free polymer binder, which can be in the form of a polymer resin and cross-linking agent. Optionally, the abrasive aggregate can contain a secondary cross-linking agent, or a functional filler, such as a grinding aid.

  • Publication number: 20100319832
    Abstract: The present invention provides a method making 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.

  • Publication number: 20100304114
    Abstract: A reinforcing web has multiple fibers joined together with a binder. At least some of the fibers have foldable portions, wherein the foldable portions have substantially less binder thereon to increase flexure to fold the web. A method of making the reinforcing web includes, applying a binder on the web, and removing some or all of the binder from a foldable portion of the web prior to curing the binder that remains on the web.
