KDSV-25 is a pourable, condensation curing 2-component silicone rubber with high elasticity for replicas using cast ceramic, plaster, polyester and polyurethane resins (please use a wax release agent as protective film with epoxy resin).
- Good flowability
- Fast vulcanisation at room temperature
- Good tear strength and tear propagation strength
Standard:- Mixing ratio: 100 : 2 parts by weight component A : component B
- Processing time: approx. 40 minutes
Alternatives:In order to achieve optimal results, we recommend mixing ratio 100 : 2 or 100 : 3
Processing time (100 g in a cup at 23 °C, humidity 50 %):
- 100 : 2 = approx. 40 minutes
- 100 : 3 = approx. 30 minutes
- Colour: White
- Dyeing: R&G Universal Color Pastes (colour differs because of the basic colour of the silicone)
- Mixing viscosity: 15.000 ± 2.000 mPa·s
- Shore A hardness: 25 ± 2
- Tensile strength: > 4.9 N/mm²
- Elongation at break: > 480 %
- Tear resistance strength: > 31 N/mm
- Shrinkage (after 7 days): ? 0.3 %
No heat of reaction occurs during vulcanization, so that even larger quantities (e.g. 10 kg) can be poured without the risk of overheating.
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 moulds 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.
