Why does my silicone mold appear oily?

Oiliness is usually caused by adding composite silicone oil (containing white mineral oil) during operation. Our silicone itself does not emit oil.

How can I prevent the silicone mold from getting burnt out?

When using unsaturated resin, demold the product within 3 minutes to avoid heat damage. Our silicone has added special materials to resist high temperatures.

What should I do if the mold is dry outside but wet inside?

This is common with condensation silicone. Add 0.05% water and stir briefly at low speed before use.
