  • Publication number: 20120322913
    Abstract: A durable substrate coating and a process of making include a resin master batch. The resin master batch can include ethylene propylene diene with a polymethylene backbone, mineral spirits, fillers, a de-tackifier, a curative, an activator component, and a metal dryer. The process can include adding the mineral spirits to: the ethylene propylene diene, a plasticizer, and the de-tackifier, and blending to form a solution. The process can include adding the fillers, a light stabilizer, a rheology modifier, and a pigment to the solution, forming a first mixture. The process can include adding another rheology modifier, another light stabilizer, an antioxidant, and a curative to the first mixture, forming a second mixture. The process can include mixing the second mixture to homogenously disperse each ingredient while maintaining a temperature of 60 degrees Celsius to prevent the mineral spirits from flashing.

  • Patent number: 8318846
    Abstract: An object of the present invention is to provide an olefin-based thermoplastic elastomer composition that has both weatherability and flexibility at low temperatures, is excellent in fluidity, and causes no stickiness even in the use at high temperatures; a process oil composition for elastomers that serves as the raw material of the thermoplastic elastomer composition and contributes to the above characteristics; and an oil-extended elastomer containing the process oil composition. The process oil composition for elastomers of the present invention has a property that, when 20 parts by weight of the process oil composition for elastomers are blended with respect to 100 parts by weight of a propylene homopolymer, the melting point of the propylene homopolymer is lowered by 2 to 4.5° C. compared to that of the propylene homopolymer without blending.

  • Publication number: 20120238694
    Abstract: The novel group of polymers is presented under the name of Powdered Metastable Polymer Material (PMPM). PMPM is in a chemically stable state at an ambient temperature of 25° C. for a relatively long time, but it is in a thermodynamically unstable state, and may change to either a stable state (in this case, re-vulcanization), or an unstable state (in this case, decomposition). According to the prior art, these PMPMs are, under various conditions, reactive, malleable, processable, compoundable, re-vulcanizable and re-polymerizable, and thus makes it possible to form new vulcanized or coagulated products, with or without moulds, with or without other polymers or elastomers, cross-linking agents, compatibilizers, various additives, etc.
