| Applications |
|
SiSiB® PC9240 may be used as synthetic equivalents for the reactive intermediate dimethylsilanone. SiSiB® PC9240 may be used as an effective trapping reagent for a variety of short-lived intermediates, including silanones and silyenes. SiSiB® PC9240 (D3) has many unique characteristics than SiSiB® PC9100 (D4). a. The reaction of SiSiB® PC9240 is more active, can be easily and quickly polymerized under lower temperature and simple catalysts. b. SiSiB® PC9240 may be used to synthesize many kinds of organic silicone products, which have better stability, better insulation properties and better water resistance. c. SiSiB® PC9240 may be used to synthesize silicon rubber, which may has better elasticity, better abrasive resistance, and better corrosive resistance. d. SiSiB® PC9240 may be used to synthesize silicone oil, which may has lower freezing point and less surface tension, it is slightly affected by temperature. |
