  • Patent number: 8926742
    Abstract: One embodiment provides a process for preparing an asphalt-coated crumb rubber composition that meets the specification set forth in ASTM D80-02 or deviations thereof which may be established by the specifying agency from time to time. The process generally comprises obtaining asphalt of different penetration grades, combining the asphalt of each grade with preselected chemicals to form separate premixed components, blending the premixed components together under predetermined conditions to form, upon curing, an asphalt-coated crumb rubber composition that meets certain physical requirements for asphalt-rubber binder (ARB), such as those set forth in ASTM D8-02. Advantageously, the resulting asphalt-coated crumb rubber composition not only meets the physical requirements of ARB used in road paving but also has improved dispersion of the rubber, such as dispersion of the rubber in an oil-in-water emulsion of an asphalt.

  • Publication number: 20100236178
    Abstract: A sealant composition for roofing shingles that includes a base asphalt, a linear and/or a radial copolymer, oil, and a wax is provided. The linear copolymer has an A-B di-block or an A-B-A tri-block structure. The radial copolymer may have an (A-B)n radial structure, where n is at least 4, or a tri-block (A-B-A) radial structure having from 4 to 8 arms. Blocks A and B may individually represent (1) styrene and butadiene or (2) styrene and isoprene. The oil is a petroleum-based oil that both “softens” the asphalt and reduces the viscosity of the sealant composition. The wax may be a bis-stearamide wax. Additionally, the sealant composition may be reacted with elemental sulfur to crosslink the copolymer blend. The sealant composition seals at temperatures lower than conventional sealants and promotes the easy release of the shingle from a shingle bundle.

  • Publication number: 20100069488
    Abstract: A composition can embrace a fire retardant can be combined with a fluoropolymer, which can be a coating, for example, a paint, especially a latex paint, or which can be an organic solvent based coating, for example, a paint. The fire retardant can be an ammonium phosphate containing fire retardant, which can be combined with a fluoropolymer, a penetrating barrier, borate-containing formulation having resistance to water damage with protective properties coming from materials used in food packaging and cosmetics, and/or a medium-to-long chain polar carboxyl substance to make a composition. Also, a composition can embrace a fire retardant formulation having a cross-linked component, which composition may be a coating, for example, a paint or stain, especially a latex paint. The cross-linked component may be a base of the paint or stain, say, a vinyl acetate base of the fire retardant latex paint. At least one other active agent, for example, a mold inhibitor and/or an insecticide, may be included.

  • Patent number: 7354653
    Abstract: Disclosed are high clarity films produced from semicrystalline polyesters by calendering. These films unexpectedly develop a higher peak melting point, which leads to higher thermal resistance. The semicrystalline polyesters may be biodegradable. When these calendered films are oriented, they develop unexpectedly high physical strength or clarity in comparison to films that are prepared by conventional techniques.
