Why does silicone rubber produce bubbles after adding the curing agent?

This is a normal physical phenomenon. Liquid produces many bubbles during mixing, so vacuum exhaust bubble treatment is required.

Q:How can I remove bubbles during mold making?

After mixing the liquid silicone with the curing agent, place the material into a vacuum machine to remove the bubbles.
