  • Patent number: 6972314
    Abstract: This invention provides a silicone resin composition giving a silicone cured rubber exhibiting a higher elongation percentage as well as improved heat resistance, oil resistance and chemical resistance, which are particularly required for automobile applications. A silicone cured rubber meeting the above physical property requirements can be prepared by moisture-curing a silicone resin composition including 100 wt parts of (a) an OH-containing polysiloxane, 0.1 to 200 wt parts of (b) a carbodiimide and (c) an organosilicon crosslinking agent, or alternatively by thermally curing a silicone resin composition including 100 wt parts of (a) an OH-containing polysiloxane, 0.1 to 200 wt parts of (b) a carbodiimide and (d) an amino-containing silane.

  • Patent number: 6451890
    Abstract: There are provided a polyamide resin composition which alleviates the drawbacks of the prior art and which is improved in resistance to hydrolysis particularly in an acidic medium of high temperatures, oil resistance and metal halide resistance; and a member made from the above polyamide resin composition, which can be applied even to sites where the use of a metallic member has been necessary. The polyamide resin composition of the present invention comprises a polyamide resin and a carbodiimide compound and, owing to the use of the carbodiimide compound, is improved in hydrolysis resistance, oil resistance and metal halide resistance; and the member of the present invention is made from the above polyamide resin composition.
