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.
