BLUESIL RTV 148 A&B (with hardener 147 B) is a two-component, addition-curing RTV-2 silicone that cures at room temperature to a softer (Shore A 40), heat-resistant elastomer.
RTV 148 A, with a viscosity of approximately 10,000 mPa·s, is significantly lower than RTV 147 A and is mixed with the hardener RTV 147 B in a 100:10 ratio. RTV 147 A and 148 A can be mixed in any proportion to adjust the hardness.
Low-viscosity, addition-curing RTV-2 silicone with a soft setting (Shore A 40), very good thermal stability and good pouring and venting properties, designed for thermal insulation and flexible insulators.

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% BLUESIL FLD 47V100. Linear shrinkage approx. 0.1% at room temperature.
