Silway 805
Silway 805 is Si-H terminated polydimethylsiloxane with varying Si-H content and viscosity, which used as chain extender in addition-cured RTV-2 formulation.
SILWAY 805 SI-H CHAIN EXTENDER FOR ADDITION-CURED RTV-2
 
 
Typical Applications
Addition-cured RTV-2
 
Key Features
  • Synergetic effect with Silway crosslinkers on mechanical properties of elastomer
  • Allows free flowing low viscosity formulations with good mechanical properties
  • Cures with vinyl-functional components without by-product formation
  • Reduces crosslinking density thereby reduce elastomer hardness
  • Suitable to formulate addition cure gel
  • Low dosage required
  • Low volatile content
