Abstract: An underlayment material has a fiber mat partially infused and/or coated with asphalt and coated with silicone coating. A selvedge edge, may be coated or uncoated. The back of the underlayment has a self-adhesive coating, which is protected before use by a siliconized release film. The upper surface of the underlayment is coated with silicone composition providing waterproofing and radiation control. When unsaturated, the selvedge edge of fibrous material establishes a reinforced bond with an overlying sheet. When saturated with asphalt, the bond at the selvedge edge between adjacent sheets is between the asphalt layer of the selvedge edge and the adhesive on the bottom of the adjacent sheet.

Abstract: As described herein, the invention includes a building underlayment sheet that comprises an underlayment lamina having a top surface and a bottom surface. The bottom surface includes an interior portion and a selvage portion that extends from the interior portion of the bottom surface to a terminal distal edge of the sheet and the interior portion of the bottom surface bears a self adhesive layer. The selvage portion of the bottom surface bears a bonding composition that is capable of bonding to a top surface of a second underlayment lamina to form a full lap joint. In some embodiments, the self adhesive layer includes an asphalt, a polymer such as poly(styrene-butadiene-styrene)(SBS), and a tackifier, and/or the bonding composition includes asphalt, a polymer such as poly(styrene-butadiene-styrene), ground tire rubber (GTR), and tackifier.

Abstract: A radiant barrier has a layer of a flexible polymer, such as TPO, and a layer of metallic aluminum bonded thereto. A reinforcement layer, such as a fiberglass scrim, and a layer of adhesive, such as EVA, may be used to strengthen the barrier and prevent de-lamination. LDPE may be incorporated into the TPO to increase strength. The barrier may also be a moisture barrier. The layers may be laminated by a heated roll set and the aluminum applied by vapor deposition.

Abstract: An adhesive composition has an asphaltic base. A plasticizer, solvent, resin, calcium carbonate, fumed silica, talc an adhesion promoter, a moisture scavenger and a catalyst are included in the adhesive. The resin may be a silylated prepolymer, two part urethane, one part urethane prepolymer, or two part epoxy. Optionally a micronized polyamide wax is added to the composition. Further optionally, an asphalt hardener and/or a silica flour may be included in the mix.

Abstract: A brush for applying a viscous coating to surfaces such as a driveway, has a composition and conformation promoting an even application of the coating. The brush has bristles of a given, number, density/spatial distribution, free length, thickness and elastic modulus that in combination provide a controlled leakage of viscous coating past the brush when the handle thereof is held at a given angle and subjected to a given downforce to facilitate applying the coating.

Abstract: A roofing material and process for making same has a granular surface formed from coated granules embedded in an upper layer of modified asphalt. The granules are coated with a coloring composition and with a hydrophobic material. To assure adequate color intensity and a physically strong attachment of the coating on the granule, multiple layers of coloring composition are applied to the granules and are fired at a high temperature for a significant period of time. High reflectivity can be achieved using the coated granules, as well as a high degree of hydrophobicity to aid in shedding water, in particular acidic rainwater to increase roofing membrane performance and useful life.

Abstract: An improved roll roof membrane for use in commercial applications, i.e., flat and low pitch roof structures, and a method for the preparation thereof. The roof membrane comprises a support sheet, and top and bottom layers comprising APP modified bitumen, the top APP modified bitumen layer having a selvage edge disposed along one side of the membrane and the bottom APP modified bitumen layer having a second selvage edge disposed along the opposite side of the membrane. Each of the selvage edges have a series of embossed ridges and valleys adapted to accept adhesives, the valleys extending substantially through the APP modified bitumen layer to the support sheet. The membrane exhibits excellent peel strength with an adhesive, thereby eliminating the need to use a torch during installation in commercial roofing applications.
