Silicone Rubber ADDV M 4601 is a pourable, addition-curing two-component RTV 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 28)
- 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 reproductions using polyurethane resin. For epoxy resins we recommend to use Priming wax to isolate the mould´s surface. Silicone Rubber ADDV M 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.
Mixing ratio: 9 : 1 component A : component B
Processing time: 90 minutes
Demouldable: 12 h at 23 °C (at 70 °C after 20 minutes)
No heat of reaction occurs during vulcanization, so that even larger quantities (e.g. 10 kg) can be poured without the risk of overheating.
If heat is added during curing (e.g. in a heating cabinet or oven), the vulcanization time is reduced by half at a temperature increase of each 10 °C. Heat thus accelerates the cross-linking reaction. The maximum recommended curing temperature is 70 °C.
Colour: Componet A: White, component B: Red, cured silicone: Reddish brown
Mixing viscosity: 10.000 mPa·s
Density: 1.13 g/cm³
Shore A hardness: 28
Tensile strength: 6.5 N/mm²
Elongation at break: 700 %
Tear resistance: > 30 N/mm
Linear shrinkage after 7 days at 23 °C: < 0.1 %
Small quantities, up to 25 kg, are specially bottled and are offered as R&G-brand.
25 kg and bigger are sold in original container with original label from Wacker ELASTOSIL®-Silicone.
*Approval by the Food and Drug Administration for food production (source: Reichelt Chemietechnik)
The Food and Drug Administration has very strict requirements for food produced in or imported to the United States. These measures were adopted to prevent national disasters caused by contaminated or polluted food. Only companies that work in accordance with FDA and whose materials are certified accordingly are allowed to serve the US market.
FDA-compliant requirements make materials necessary that have a long shelf life and do not release any ingredients into the food. In the food sector, a large number of plastics with fundamentally different properties are used and come into contact with food. All these plastics must be FDA-compliant and their requirements selected accordingly.
