ELASTOSIL® SC 835 A/B

About
RTV-2 SILICONE FOAM ELASTOSIL® SC 835 A/B is a pourable, addition-curing, two-component silicone rubber, forming a mainly closed cell foam. Special features low processing viscosity good processability on automated dispensing equipment easy control of mixing quality due to different colors of the components no ozone damaging blowing agents no release of toxic or strong smelling substances during foaming or curing low heat of reaction (max. 40 °C) low toxicity of thermal decomposition products (only traces of CO) long-term flexible over a temperature range of -50 °C to +200 °C good chemical resistance Application general purpose high and low temperature resistant sealing material suitable for sound and heat insulation shock and vibration damping at high temperature changes&&
