Polymer modified asphalt roofing material
A shingle coating asphalt composition is provided that is produced from a paving grade asphalt. The asphalt composition comprises a paving-grade asphalt that has been modified with one or more polymer additives; and a secondary additive comprising one or more of a viscosity reducing agent, a wax, a salt of a fatty acid ester, and an amide of a fatty acid. The shingle coating asphalt coating composition is used to make a shingle. The shingle includes a substrate, the asphalt, and roofing granules.
Fire Resistant Compositions, Coatings, and Related Methods and Building Assemblies
The invention as disclosed herein includes a composition for increasing the fire resistance of a substrate. The composition is composed of a solvent; a polymer binder; a carbon-based flame retardant; a fire retardant compound, such as a phosphorous based flame retardant compound or a char forming flame retardant; a heat absorbing compound; and a phyllosilicate material. Also included are methods of reducing the flammability of a substrate or of increasing the fire resistance of a substrate by applying the composition of the invention, wherein the inflammability of the substrate is improved when compared to an identical substrate that is not coated with the composition. Fire resistant coatings prepared from the composition of the invention are disclosed. The assemblies described herein exhibit improved fire resistance as compared to an identical assembly that does not include the coating.

SCALABLE METHOD OF FABRICATING STRUCTURED POLYMERS FOR PASSIVE DAYTIME RADIATIVE COOLING AND OTHER APPLICATIONS
A structured material is provided that includes a substrate and a porous structured polymer layer disposed thereon. The porous structured polymer layer includes a plurality of voids, and has a high hemispherical reflectance a high a hemispherical thermal emittance. The structured material is thus particularly advantageous for cool-roof coatings, enabling surfaces coated by the material to stay cool, even under strong sunlight. The material can be produced via structuring of polymers in a mixture including a solvent and a non-solvent. Sequential evaporation of the solvent and the non-solvent provide a polymer layer with the plurality of voids.
