Silicone rubber KDSV M4470, heat resistant (set of 2 comp.)

2 component, pourable, condensation-curing, flexible cast mould mass for replicas using low-melting metal alloys (tin, lead)

Mixing ratio: 100 : 2 parts by weight silicone : catalyst 40
Processing time: 40 minutes
Time to demoulding: 3–4 h at 23 °C

Mixing ratio: 100 : 3 parts by weight silicone : catalyst 40
Processing time: 20 minutes
Time to demoulding: 2–3 h at 23 °C

Heat resistance: up to 300 °C
Mixing viscosity (23 °C, before catalysing): 10 000 mPa·s (= pourable)

No heat of reaction occurs during vulcanization, so that even larger quantities (e.g. 10 kg) can be poured without the risk of overheating.

Colour: Reddish brown
Dyeing: R&G Universal Color Pastes (colour differs because of the basic colour of the silicone)
Density: 1.4 g/cm³
Shore A hardness: 60
Elongation at break: 120 %
Tear strength: >4 N/mm
Linear shrinkage as per 7d/RT: 0.8 %
