Eco-friendly liquid silicone rubber raw material for mask making/artificial leg casting
Description of Eco-friendly liquid silicone rubber raw material for mask making/artificial leg casting:
environmental liquid silicone rubber can be made of flexible silicone rubber products, such as sex products, body shape, body parts, body shape, chest pad, shoulder pads, patch, anti-skid pad, but also for the simulation of human facial silicone mold is mainly used for human face imitation of human body shape , because it is food grade, can be used to produce food mold, high-grade silicone products.

Operation Instruction eco-friendly liquid silicone rubber:
Liquid silicone rubber raw material is a kind of flowing liquid, and it consists of two component, part a is a flow-able liquid silicone rubber, part B is the curing agent.
1. Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber, add 2%~3% cuing agent of the amount of silicon and mix themevenly.
2. Then after vacuum-pumping the mixture, you can pour it into the mold frame.
3. The silicone mold will cured in 2~3 hours.
Note: the time for vacuum-pumping should be less than 3-5mins, otherwise, once the silicone rubber has cross-link reaction during vacuum. it will not be operated.
