Product Description
Description
Roman column mold silicone is a kind of specialized mold making silicone rubber for roman column.According to the large size and heavy performance.ChenYang has a dedicated product for roman column mold making.Part A is flow-able liquid silicone,part B is vulcanizing agent,the mixture can form quickly after mixing part A and part B,it is easy to operate.
Features
1. Good fluidity,easy-operation,non-deformation,suitable for delicate or intricate pattern decorative building products.
2. Good weather resistance,high and low temperature resistance, acid and alkali resistance,aging resistance.
3. High tension and tear strength,low shrinkage.(the shrinkage of condensation cure silicone rubber is less than 0.3%,the shrinkage of addition cure silicone rubber is less than 0.1%)
4. High duplication times,such as the duplication times of plaster can reach more than 1000 times.
5.Can be cured at room temperature or cured by heating quickly.
6.Easy to release bubbles, easy pouring and demoulding.
