2. Main features of liquid silicon rubber to make mold for conrete with low shrinkage
1. Good characteristics of easy-operation
2. Light viscosity and good flowability
3. Low shrinkage
4. Excellent tensile and tear strength
5. Favorable hardness
6. High temperature resistance, acid and alkali-resistance and ageing resistance
7. High duplication times
3. Discription of liquid silicon rubber to make mold for conrete with low shrinkage
Liquid silicon rubber to make mold is a kind of flowable liquid silicone, the quality has nothing to do with the color. It consists of two components. Part A is a flowable liquid silicone rubber, part B is the curing agent. Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber, add 2%-3% curing agent of the amount of silicon, and mix them evenly. Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2-4 hours.
And more curing agent is needed; Contrarily, if molds requiring slower drying and demould, less curing agent is needed.
