RTV molding silicone rubber for plaster products frequently asked question:

Why is the silicone rubber mold oily?

Basically, molding silicone rubber doesn't contain any oil, so it won't be oily. The reasons for the oily molds can be deducted from the below 3 factors:

1. Added white oil, which is the compound of silicone oil and white oil. The white oil is not silico ne oil but a kink of petrochemicals;

2. Added too much silicone oil. Normally, we donot advise our customers to add any silicone oil into silicone rubber. If necessary, the ratio must be 5%-10%;
