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
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
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
