Silicone - polyurethane casting 1kg

Beskrivning

Durable and specially designed for casting hard baits.

The silicone has a good detail reproduction while still being strong. Silicone DC 3481 R is excellently suited for casting e.g. cement, plaster, wax, soap and many other casting materials but also for aggressive resins such as polyurethane, epoxy and polyester.

Mixing ratio by weight: A:B = 100:5

Pot life at 23°C: 90-120 minutes

Viscosity mixture at 23 °C: 20,000 mPa⋅s

Hardness: Shore A 18~21

Tensile strength: 46 kg/cm2

Tear strength: 26 kg/cm

Linear shrinkage: 0.2-0.4%

Full strength after: 3 days

Note: Pot life and curing time are highly dependent on the mixing ratio and humidity! Adding more than 5% silicone B (hardener) or at high humidity will shorten the pot life and curing time.
