Silicone rubber KDSV-25 (set of two components)

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 priming wax as protective film with epoxy resin).

• Good flowability
• Fast vulcanisation at room temperature
• Good tear strength and tear propagation strength

Technical data:

Standard:

Mixing ratio: 100 : 2 parts by weight component A : component B
Processing time: approx. 45 minutes

Alternatives:

Mixing ratios from 100 : 2 up to 100 : 5

Processing time (100 g in a cup at 23 °C):
100 : 2 = approx. 45 minutes
100 : 3 = approx. 30 minutes
100 : 4 = approx. 15 minutes
100 : 5 = approx. 10 minutes

Demouldable after: approx. 30 minutes - 12 hours, depending on addition of crosslinker

Colour: White
Dyeing: R&G Universal Color Pastes (colour differs because of the basic colour of the silicone)
Mixing viscosity: 18.000 mPa·s
Density: 1.08 g/cm³
Shore A hardness: 25
Tensile strength: ≥ 4.0 N/mm²
Elongation at break: ≥ 430 %
Tear resistance strength: ≥ 27 N/mm

No heat of reaction occurs during vulcanization, so that even larger quantities (e.g. 10 kg) can be poured without the risk of overheating.
