4.Operation Steps of liquid silicone rubber for stone molds:

Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.

Notes: Moulding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent.

Step Two: vacuum pumping

Without exception, this step takes less than 10 minutes.

Note: The time for vacuum-pumping should be less than 3—5 mins , otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.

Step Three: Brushing cast & Perfusion Molding operation

5.FAQ of liquid silicone rubber for stone molds:

Why does the liquid silicone rubber for gpusm products' mold making mold get burnt out?

The unsaturated resin produces great heat when added the curing agent. So you must demould the product within 3 minutes to avoid this problem.
