Message
Techsil RTV27909 is a kit matched easily pourable, solvent free, clear and colourless two-component silicone gel. After mixing the A and the B part at a mix ratio of 1: 1 the material cures very fast at room temperature by an addition reaction to a tacky silicone gel with excellent vibration dampening properties.

Properties:
  • Convenient 1:1 mixing by weight
  • Low viscosity, free of solvents
  • Fast room temperature cure
  • Soft, tacky gel, sticking to many substrates
  • Mechanical shock and vibration damping properties
  • Useful temperature range -50°C to 150°C

Applications:
Techsil RTV27909 is specially developed for electronic potting applications such as hybrid IC insulation, potting of power modules and sensors when fast cure at room temperature is required.
