Silicone rubber ADDV-42 RED (set of two components)

Silicone rubber ADDV-42 RED (set of two components)


ADDV-42 RED is a pourable, addition-curing 2-component RTV silicone rubber particularly suitable for the reproduction of models with undercuts using polyurethane and epoxy resins.

  • Superior flowability
  • Fast, shrinkage-free vulcanisation at room temperature
  • Good tear strength and tear propagation strength

Application:

  • Particularly suitable for the reproduction of models with undercuts using polyurethane and epoxy resins
  • Moulds with high thermal stability and heat dissipation for casting low-melting metal alloys (such as lead and tin, melting point: max. 250 °C). To increase the service life of silicone moulds for lead and tin casting, talcum powder can be used.

Processing:

Mixing ratio: 1 : 1
component A : component B
Processing time
(at 25 °C): 30-50 minutes
Demouldable
(at 25 °C): After 4-5 hours

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. The heat thus accelerates the cross-linking reaction. The maximum recommended curing temperature is 70 °C.

Please note:

  1. Cannot be processed with our Universal Colour Pastes.
  2. The air stirred in during mixing can be removed by vacuuming in a desiccator. This ensures that the silicone is free of air bubbles to the maximum.
  3. For all equipment and tools used, make sure that no other materials such as epoxy resins or condensation-curing silicones have been processed beforehand. Addition-curing silicones may react to impurities with curing problems.

Linear shrinkage after 7 days at 23 °C: ≤ 0.1 %

Colour:
Component A:
Translucent
Component B:
Red


Additional information:

Delivery:
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 catalyst.
Packs of 0.5, 1, and 2 kg are supplied in squeeze bottles and 10 and 20 kg in PE canisters.

Customer information:
The release agent Semiperm™ Monofilm in combination with PARTALL® Coverall Film PVA is suitable as a safe release agent for silicone moulds. This combination of release agents provides a barrier layer so that casting with epoxy resins is also possible without any problems. The service life (durability) of the molds is significantly extended.
The release agent Semiperm™ Monofilm is applied with a brush. After flash-off, PARTALL® Coverall Film PVA is applied, also with a brush or sponge. For more information on processing, see the release agents.
PARTALL® Coverall Film PVA is transferred to the casting, washed off with water after demolding and reapplied before each impression.
