BLUESIL RTV 147 A&B is a two-component, addition-curing RTV-2 silicone that cures at room temperature into a heat-resistant, elastic molding compound with Shore A 60 hardness.
RTV 147 A is processed with hardener RTV 147 B in a ratio of 100:10 and forms a flowable paste after mixing, which cures without reaction heat. 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 °C), good reversion resistance, and good dielectric properties, designed for thermal protection and the embedding of electrical systems.

Important Notes
- Addition curing is sensitive to inhibition: avoid sulfur-containing rubbers, metal-salt-catalyzed RTV, tin-stabilized PVC, and amine-crosslinked epoxides; if in doubt, test beforehand.
- Viscosity can be reduced before curing with up to 10% BLUESIL FLD 47V100; more will affect the properties of the finished parts. Linear shrinkage approx. 0.1% at room temperature.
- The currently valid Elkem data sheet (TDS and SDS) is authoritative, which we will be happy to send you.
