Base and Curing Agent Mixture (100:2 by weight) in 25 °C (77F) testing.
Features of molding silicone rubber :
1.Outstanding release properties
2. High flow-ability and long working time
3. Medium Hardness
4. High tear resistance
5. High elasticity for easy removal of complex replica parts
6. Can be made thixotropic (non flow-able) for vertical surface replication
Operation Instruction for molds molding silicone rubber :
Molding Silicone Rubber 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 them evenly.
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.
