Abstract: The present disclosure relates to cementitious articles that are reinforced with a fabric made at least partially of high modulus polyolefin monofilament fibers. Preferably, the polypropylene monofilament yarns have a 3% secant modulus of elasticity of at least 100 g/denier. The high modulus polypropylene fabric has an intrinsic resistance to the alkaline conditions present in a cementitious composite, as well as a low elongation at break. The high modulus polypropylene may contain a nucleating agent to facilitate the process of obtaining desired draw ratio.

Abstract: Alkaline resistant fibrous products containing a binder comprised of a blend of urea formaldehyde and melamine formaldehyde and having particular use in bonding to alkaline materials having a pH of about 8 or above, including cementitious boards and other shapes, to provide manufacturing aids, reinforcement, fire resistance and a smooth surface are disclosed. Laminates containing one or more of the alkaline resistant fibrous products, with fibers bonded together with melamine formaldehyde and optionally a blend of urea formaldehyde and melamine formaldehyde binder, in contact with at least one cementitious layer are disclosed. Also, methods of making the alkaline resistant fibrous products and laminates that contain one or more layers of the alkaline resistant fibrous products are disclosed.

Abstract: A method and product for identifying the origin of products having fiberglass components or constituents wherein the glass fibers are coated with a fluorescent agent that glows when subsequently subjected to UV or appropriate wavelength light. Thus by selecting a unique color or pattern a manufacturer can readily identify his products.

Abstract: Disclosed are a fire retardant laminated sheet and a manufacturing method thereof. The laminated sheet for various interior applications exhibits improved fire retardancy, so it does not burn in a fire. Such a fire retardant laminated sheet is manufactured by impregnating a fire retardant material with an impregnant containing phenolic resin, to have 25 to 35% resin impregnated by weight, obtaining a sheet base. Then, a melamine resin impregnated paper is stacked on one or both faces of the sheet base thus obtained, and the resultant stacked paper is molded under heat and pressure, using a press, at 130 to 140° C. for 15 to 30 min under a pressure of 50 to 60 kgf/cm2.

Abstract: Plastic deformable material web, more particularly bitumen web for use preferably in roofing applications. The material web comprises a modelling mesh as the backing material and at least one plastic deformable covering material layer such as a bitumen layer connected to the mesh. For joining the mesh (4′) to the covering material layer (2′) a thin foam web (3′) is bonded or thermally laminating to the mesh. The foam prevents detachment of the bitumen layer from the mesh due to cold flow and prevents sagging of the bitumen even at high temperatures (FIG. 2).

Abstract: The invention provides a glass fiber facing sheet for engineered surfaces such as cement boards which reduces the pitting associated with open mesh glass scrims. The glass fiber facing sheet comprises an open mesh glass scrim having a plurality of intersecting continuous multifilament yarns which are bonded at their crossover points to provide dimensional stability to the scrim. A melt blown polymer web is preferably joined to one face of the glass scrim and covers the mesh openings in the scrim. The opposed face of the scrim defines an exposed grid profile surface which is available for mechanical interaction between the scrim and the cementitious slurry used in cement boards. In cement boards, the glass fiber facing sheet of the present invention is preferably mechanically integrated into a surface portion of the cement core along the exposed grid profile of the scrim.
