1. Application
  
  Vulcanization: XIAMETER RBB-2200-75 Base requires the addition of a vulcanizing agent. T catalyst (2, 4 dichloro-benzoyl peroxide) is recommended for hot air vulcanization. V catalyst (2,5 bis[tertbutylperoxy] -2,5-dimethylhexane) or D catalyst (dicumylperoxide) is recommended for molding.
  
  Pigmentation: This silicone rubber base can be pigmented with standard XIAMETER™ Pigment Masterbatches.
  
  Property Modification: The physical properties of this product can be modified using a range of Dow additives.
  
  For more detailed information on the use of Dow additives, please contact your local technical representative.
  
  This silicone rubber base can be blended with other durometer silicone rubber bases to produce materials with intermediate durometers and properties.
