Silicone rubber ADDV-10 TRANSLUCENT (set of two components)

ADDV-10 is a pourable, addition-curing 2-component RTV silicone rubber particularly suitable for the reproduction of models with undercuts using polyurethane and epoxy resins.

• Excellent flowability
• Easy to process
• Low shrinkage
• Good tensile and tear strength
• Easy to de-mold
• Excellent resistance to high temperatures (200 °C), chemicals and aging
• Environmentally friendly

Application:

Single or multi-part moulds can be produced for the molding of original models of wood, glass, metal, plastic, wax and ceramic casting compounds.

In the produced moulds you can cast with all water-soluble casting materials:

• Waxes and soap
• Plaster
• Casting resins* (Polyurethane, epoxy, and polyester resins)
• Medical casting compounds (eg. dental technology)

*Here you should pre-treat the mould with a release agent before pouring since casting resins can lead to the embrittlement of the mould after repeated casting.

Processing:

Mixing ratio: 1 : 1 component A : component B
Processing time (at 25 °C): 30-40 minutes
Curing time (at 25 °C): 4-5 h

No heat of reaction occurs during vulcanization, so 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 makes the silicone maximally free of air bubbles.
3. With all equipment and tools used, care should be taken that no other materials such as epoxy resins or condensation-curing silicones have been processed with them beforehand. Addition-curing silicones may react to impurities with curing problems.

Delivery:
As both component batches match each other, we only supply complete batches. It is not possible to obtain individual deliveries of silicone and catalyst.
Packages with 0.5, 1 and 2 kg in a squeeze bottle, 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.
