BLUESIL RTV 147 A&B is a two-component, addition-curing RTV-2 silicone that cures at room temperature to form a heat-resistant, elastic molding material with Shore A 60.
RTV 147 A is mixed with hardener RTV 147 B in a 100:10 ratio and forms a flowable paste after mixing, which hardens without generating heat of reaction. RTV 147 A and 148 A can be mixed in any ratio to achieve a medium hardness.
Addition-curing RTV-2 silicone with very good thermal stability (peak temperature up to approx. +300 degrees C), good reversal resistance and good dielectric properties, designed for thermal insulation and the embedding of electrotechnical systems.

Important instructions
- Addition crosslinking is sensitive to inhibition: avoid sulfur-containing rubbers, metal salt-catalyzed RTV, tin-stabilized PVC and amine-crosslinked epoxides; test in advance if in doubt.
- Viscosity before catalysis can be reduced by up to 10% with BLUESIL FLD 47V100; higher concentrations will impair the properties of the finished part. Linear shrinkage is approximately 0.1% at room temperature.
- The relevant information is the current Elkem data sheet (TDS and SDS), which we will gladly send you.
