  • Patent number: 11414547
    Abstract: An oil containing an oil mist suppressant is provided herein. The oil can be a fiber treatment oil, spinning oil, or textile treatment oil. The oil mist suppressant suppresses the formation of oil mist from the oil during treatment using the oil. In general, the oil mist suppressant will not inhibit the purpose and effects of the oil treatment. A method of reducing oil mist using the oil mist suppressant is also provided herein. The oil mist suppressant is constituted by a silicone fluid composition. The silicone fluid composition is homogeneously miscible with a dimethylpolysiloxane oil having a kinematic viscosity of 10.0 mm2/s at 25° C. The silicone fluid composition also has the property of increasing the maximum lamellar length of the dimethylpolysiloxane oil by at least 5% when 1.0% by mass of the silicone fluid composition is added thereto.
    Type: Grant

  • Patent number: 6433122
    Abstract: A method for producing organopolysiloxane comprising (A) polymerizing or increasing the viscosity of straight-chain or cyclic organo(poly)siloxane using an acid-active solid catalyst, (B) adding at least one zeolite solid adsorbent, and (C) thereafter filtering off the adsorbent.

  • Patent number: 5684110
    Abstract: A silicone rubber composition which can be used to provide a formed-in-place gasket which exhibits excellent pressure resistance immediately after its site application and cures into a highly pressure-resistant and strongly adherent silicone rubber gasket comprising (A) 100 weight parts of a mixture of comprising an alkoxy-substituted polyorganosiloxane and an alkenyl-substituted polyorganosiloxane; (B) a hydrogen-containing polyorganosiloxane an alkoxysilane; a condensation reaction catalyst; and platinum catalyst.
