Product Details

Silicone rubber ADDV-25 BLUE, squezze bottles (A+B)

 
 

Description

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

Now NEW in squeeze bottles.

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 vulcanization at room temperature
  • Good tear strength and tear propagation strength

Technical data:
Mixing ratio: 1 : 1 component A : component B
Processing time (at 25 °C): approx. 30-50 minutes
Demouldable (at 25 °C): 4 - 5 h
Mixing viscosity: 3.000 ± 300 mPas
Shore A hardness: 25 ±2
Tensile strength: > 5.5 N/mm²
Elongation at break: ≥ 680 %
Tear resistance: > 29 N/mm
Linear shrinkage: ≤ 0.1 %

Color:
Component A:
Translucent
Component B: Blue

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.

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 vulcanization interfering substances (Shore-Hardness and processing information) 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.

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.
