RTV molding silicone rubber for plaster products operation way:
Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Step Two: vacuum pumping.Without exception, this step takes less than 10 minutes.
Note: The time for vacuum-pumping should be less than 3—5 mins , otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.
Step Three: Brushing cast & Perfusion Molding operation
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%;
Good deal: buying from seller
