Silicone ADDV M 4641, transparent (set of two components)

Технические характеристики

• Pourable, addition-curing two-component silicone rubber with high extensibility (approx. 300 %)
• Transparent vulcanisate
• Fast, shrinkage-free vulcanisation at room temperature
• Superior tear strength and tear propagation strength
• Medium hardness (Shore A 43)
• Very high resistance to cast resins, in particular polyure-thane and epoxy resins, for a large number of demouldings
• Heat-resistant up to 180 °C
• Suitable for food contact in accordance to BfR and FDA

Silicone 4641 is a high performance cast mould mass particularly suitable for the reproduction of models with undercuts using polyester resins, polyurethane resins and epoxy resins.

Due to the transparency of the vulcanized silicon it is possible to see -inside the mould when casting the reproductions. One of the main uses is vacuum casting for rapid prototyping.

As both component batches are matches to each other, we only supply complete batches. It is not possible to obtain individual deliveries of silicone and hardener.

• Mix ratio: 10 : 1 Component A : Component B
• Processing time: 100 minutes
• Removable from the mould at 23 °C: after 15 h, at 70 °C after 30 min
• Mix viscosity: 30 000 mPa·s (= pourable)

Colour: transparent, density: 1.07 g/cm³, hardness Shore A: 43, elongation at break: 300 %, tear strength: > 25 N/mm, linear shrinkage as per 7 d/RT: < 0.1 %
