Q: Why is the silicon mold oily?
A: The molding silicone rubber itself doesn’t contain any oil, so it won’t be oily. If the mold is oily, it may be because of two reasons:
You add the compound silicone oil (the compound of silicon oil and white oil). The white oil is not silicon oil but a kind of petrochemicals.
Your supplier adds to much silicone oil when they producing silicone rubber or reducing the hardness of silicone rubber.
Q: How to get rid of the bubbles during my mold making?
A: After mixing liquid silicone with a curing agent, please put the materials into the vacuum machine to take off the bubbles
