Silicone rubber ADDV-25, translucent (set of two components)

from 18,65 € / kg

Rate item

Description

ADDV-25 is a pourable, addition-curing 2-component RTV silicone rubber particularly suitable for the reproduction of models with undercuts using polyurethane and epoxy resins.

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.

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

Technical data:
Mixing ratio: 1 : 1 component A : component B
Processing time: 60 minutes
Demouldable: After 14 h at 23 °C (after 25 min at 70 °C)

Color: Translucent (not transparent)
Mixing viscosity: 6.000-8.000 mPas
Density: 1.07 g/cm³
Shore A hardness: 25
Tensile strength: ≥ 4.2 N/mm²
Elongation at break: ≥ 400 %
Tear resistance: ≥ 26 N/mm
Linear shrinkage after 7 days at 23 °C: ≤ 0.001 %

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.

Caution:
Cannot be processed with our Universal Colour Pastes.

We recommend a test by pouring the mixture of the two components into a limited area of the mould.

The vulcanisation interfering substances (see R&G eWiki) can be on surfaces and also in the ambient air, so it is important to use non contaminated tools and equipment, which were not in contact with them.
