  • Patent number: 11674042
    Abstract: A latex emulsion may include an aqueous carrier liquid and a latex copolymer formed from reactants comprising butyl methacrylate, wherein the reactants include at least 20 wt. % butyl methacrylate, based on the total weight of ethylenically unsaturated monomers used to make the latex copolymer. A coating formed from the latex emulsion exhibits a wet adhesion to a thermoplastic polyolefin roofing membrane of greater than about 1 pound per linear inch when tested using fabric embedded peel adhesion testing per ASTM C794. The latex emulsion may be used as part of an aqueous coating composition or a roofing system including a polymeric roofing membrane.

  • Publication number: 20210292594
    Abstract: A latex emulsion may include an aqueous carrier liquid, a first (meth)acrylic copolymer or stage exhibiting a measured glass transition temperature between about ?15° C. and about ?50° C., and a second (meth)acrylic copolymer or stage exhibiting a measured glass transition temperature between about ?10° C. and about 20° C. The first and second (meth)acrylic copolymers or stages may include less than about 20 weight percent styrene, if any, based on the total weight of emulsion polymerized ethylenically unsaturated monomers in the first and second (meth)acrylic copolymers or stages. The latex emulsion may be formulated into an aqueous coating composition and be used as a cool roof coating for bituminous materials, such as bituminous roof materials.

  • Publication number: 20070158624
    Abstract: Time temperature indicators are disclosed which comprise at least one carrier material and one aggregachromic indicator dye and which respond to the combined effects of temperature and time with an easily measurable, time-temperature dependent, irreversible, color change. The invention also discloses to methods to produce such time-temperature indicators and materials therefore. Also, the devices disclose methods for determining the time/temperature history.
