Abstract: A reinforcing tape for imbedding in a joint compound, has reinforcing yarns defining openings for passage of the joint compound, wherein; the openings are bounded by the yarns; the yarns are provided with one or more coatings adding tensile strength and resistance to pull out of the yarns from the joint compound.

Abstract: A reinforcement mesh, an architectural moulding reinforced by the mesh, and methods of making the architectural moulding and the mesh. The mesh is adhered by an adhesive to the architectural moulding. In the mesh, weft yarns bend relative to warp yarns to conform to and against a curved profile of the architectural moulding, and the warp yarns are unbent and adhered against the moulding.

Abstract: The invention pertains to a drywall tape having a nonwoven fabric and a reinforcing scrim, wherein the nonwoven fabric has chopped glass fibers laid flat in the nonwoven fabric, the fibers being substantially straight, random laid and bonded to one another to resist forces exerted in random directions, and the reinforcement scrim has elongated reinforcing strands of low profile thickness joined against a side of the nonwoven fabric, such that the scrim and the nonwoven fabric reinforce each other, and reinforce a joint compound in which the drywall tape is imbedded.

Abstract: Methods and a reinforcement fabric are disclosed for making a reinforced smooth cementitious board having a cement skin adjacent to an outer face, by depositing a reinforcement fabric and a layer of hydraulic cementitious material, one on the other, wherein the reinforcement fabric comprises an open mesh united with a thin, porous nonwoven web.

Abstract: A reinforcing drywall tape and a method of making the same, the tape having a greige combined with a laid scrim constructed in situ on the greige and bonded to the greige by a resin coating, and a pressure sensitive adhesive fully covering an inward facing surface of the greige wherein the greige is adapted for adherence to drywall sections.

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.

Abstract: A reinforcing drywall tape and a method of making the same, the tape having a greige combined with a laid scrim constructed in situ on the greige and bonded to the greige by a resin coating, and a pressure sensitive adhesive fully covering an inward facing surface of the greige wherein the greige is adapted for adherence to drywall sections.

Abstract: A cementitious board and a reinforcement sheet for the board includes, a water vapor porous layer of glass fibers bonded together by a cured binder, and a hydrophilic coating material being mobile in slurry water to wet the binder coated glass fibers and spread a slurry of a cementitious compound, and the hydrophilic coating material being volatile to dissipate by evaporation at an elevated temperature at which the cementitious compound dries to form a dried cementitious board having both the cementitious compound and the binder coated glass fibers essentially free of the hydrophilic coating material.

Abstract: A composite material comprises: an open grid comprising at least two sets of strands. Each set of strands has openings between adjacent strands. The sets are oriented at a substantial angle to one another. A tack film is laminated to the open grid. The tack film has first and second major surfaces, such that a material of the tack film at its first and second major surfaces includes about 50% or more of resinous non-asphaltic component and about 50% or less of asphaltic component.

Abstract: A method of making a reinforcement sheet for a cementitious board includes applying a hydrophilic coating material on binder coated glass fibers, the hydrophilic coating material being mobile in slurry water at a surface of a slurry of a cementitious compound to dilute and disperse, and to wet and spread the slurry on the binder coated glass fibers, and the hydrophilic coating material in the slurry water being volatile to dissipate by evaporation at an elevated temperature at which the cementitious compound is dried for the binder coated glass fibers to be essentially free of the hydrophilic coating material.

Abstract: The present invention provides thickened fabrics and reinforcements for use as a spacer or reinforcement for a matrix system. The fabric includes in a first embodiment a woven fabric comprising weft and warp yarns containing glass fibers. A portion of the weft yarns are undulated into a sinusoidal path forming a generally “C” shaped bridge between adjacent warp yarns which results in an increased thickness for the fabric. The fabric is coated with a polymeric resin or bonding agent, for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making such fabric by increasing the thickness of a woven or non-woven material by such methods as applying tension to warp yarns having opposite twists during weaving operations, or using unbalanced yarns, for example.

Abstract: A method for making a reinforcement material comprises providing at least one strand of carbon fibers. A polyolefin coating is applied. A coating comprising an inner layer of a first polyolefin material and an outer layer of a second polyolefin material may be coextruded on the at least one strand. The first polyolefin material has a substantially lower viscosity than the second polyolefin material at an extrusion temperature of the coextruding step. Alternatively, polyolefin fibers may be core sheath spun on the strands to coat the strands, and the coated strands of carbon fibers formed into a woven or knit fabric or a non-woven mesh for a reinforcing a material.
