Технические характеристики
- Pourable, addition-curing two-component silicone rubber with high extensibility (approx. 450 %)
- Superior flowability
- Fast, shrinkage-free vulcanisation at room temperature
- Superior tear strength and tear propagation strength
- Soft (Shore A: approx. 26)
- Superior long-term stability of the vulcanisate's mechanical properties
- Very high resistance to cast resins, in particular polyurethanes
- Heat-resistant up to 180 °C
- Suitable for food contact in accordance to BfR and FDA
Flexible cast mould mass used especially for reproduktions, e.g. using epoxide resin. Contrary to Silicone 4503 it is possible to achieve c. 30 cast moulds with EP resin without release agents. Silicone 4601 is addition-curing and, similar to epoxy resin, needs to be mixed exactly with the appropriate hardener.
As both component batches are matched to each other, we only supply complete batches. It is not possible to obtain individual deliveries of silicone and hardener.
- Mix ration: 9 : 1 Component A : Component B
- Processing time: 90 minutes
- Removable from the mould at 23 °C after 24 hours, at 70 °C after 20 minutes
- Mix viscosity 20 000 mPa·s (= pourable).
Colour: reddish brown, Shore A: 26, elongation at tear: 450 %, tear propagation resistance: > 20 N/mm, linear shrinkage as per 7 d/RT < 0.1 %
