      Mass   Fraction of Trimethyl chlorosilane %(m/m)≥



      Applications :it is mainly used in the production of MM end –capping agent,silazane,cephalosporin anti-biotic,protection agent of active groups’reaction ect.


      Hazard Characteristics :inflammation and explosion will arise when it meets naked fire,high heat or oxidant .And it will decompose with exothermic heat and poisonous caustic smoke when it is heated or encounter water .interior pressure in the vessel increases leading to the danger of splitting and explosion when it meets high heat.




      Polymerized Danger:Free of being polymerized


      Condition to Avoid being Contacted :humid air


      Banned Articles :strong acid ,water,strong alkali


      Decomposition products:chlorine hydride ,siloxane etc.


      Package ,storage and  transportation :It should be packed in 200L iron bucket (net weight 160kg/bucket)and be stored in a shady ,cool and ventilated storehouse .It should be kept away from kindling or heat sources .temperature in the storehouse above 30 ℃ is not suitable .Avoid direct sunlight .Air proof package is required without contact with air .And it should be put and stored separately from oxidant ,acid ,and alkali .the installation of lighting and ventilation in the ware house should be explosion proof.Switches are located outside the storehouse .corresponding varied and quantitative fire flighting equipment should be equipped.Technical measures of fireproofing and explosion prevention should be taken when it is stored in the pots.Mechanical equipment and tools which are easy to produce sparks are prohibited to be used .Check regularly make sure whether there is a leakage phenomenon .Operate and handle in nitrogen gas .when conveying .take care of loading and unloading to avoid damage on package and vessels .Aregulated  route is required for transportation without stay on the midway.

      Quality guarantee period  of this product is 6 months .Recheck by this standard is required when the product exceeds the time limit .The product can still be used only after the result of recheck is up to the standard.
