摘要:
A method for preparing a bituminous roofing article, the method comprising: (i) applying a fluorine-containing compound to a plurality of granules; (ii) depositing the plurality of granules on an asphaltic substrate; where the fluorine-containing compound is defined by the formula (V) or (VI): wherein r and q are independently integers of 1 to 3; Rf is linear or branched chain perfluoroalkyl group having 1 to 6 carbon atoms; j is an integer 0 or 1, or a mixture thereof, x is 1 or 2, X is hydrogen or M, and M is an ammonium ion, an alkali metal ion, or an alkanolammonium ion; and (iii) applying a silicone oil to the surface of the granules.

摘要:
A method of manufacturing a granule coated asphaltic article comprising the steps of applying liquid asphalt to a reinforcing sheet to create an asphaltic sheet, the asphaltic sheet having a top surface and a bottom surface; bending the asphaltic sheet to form an arcuate top surface of the sheet; and applying a coating of granules over the arcuate top surface of the asphaltic sheet.
摘要:
A roofing article comprising (i) an asphaltic substrate; and (ii) a plurality of granules disposed on a surface of the substrate, said granules including calcined kaolin that has been calcined at a temperature of at least 1000° C. and less than 1300° C.
摘要:
A bond adhesive composition comprising a polymer having a silicon-containing hydrolyzable terminal group and a hydrocarbon resin, where the composition is substantially devoid of phenolic resin.
摘要:
A roofing membrane comprising an olefinic rubber; and from about 20 to about 250 parts by weight of a silica filler per 100 parts by weight rubber; wherein the silica filler is chemically coupled to the olefinic rubber; and wherein the roofing membrane is non-black.
摘要:
A method for producing an asphaltic sheet having expandable graphite dispersed in one or more asphaltic components thereof, the method comprising preparing a masterbatch by combining asphalt binder and polymeric modifier at a first temperature, cooling the masterbatch to a second temperature, where the second temperature is lower than the first temperature, adding, after said step of cooling, expandable graphite to the masterbatch to thereby form an asphaltic composition including expandable graphite, and fabricating a sheet with the asphaltic composition including expandable graphite.
