Two Components Mold Making Silicone Rubber
Two components mold making silicone rubber is made up of part A and part B, part A is silicone rubber liquid, part B is curing agent (tin catalyst or platinum catalyst). The amount of curing agent you add is on the basis of your requirement, In general, the amount of tin catalyst you add is around 2% to 5%, and the amount of platinum catalyst is 1:1 or 10:1. The curing time depends on the amount of the curing agent you add, if you want the silicone rubber be cured quickly, you can add more curing agent.
Two components mold making silicone rubber has the features of high temperature resistance, high tensile and tear strength, low shrinkage, acid and alkali resistance, high duplication times, non-deformation.
The silicone oil is not suggested, which can destroy the structure of silicone rubber. If necessary, the silicone oil is obtained at addition of 5% to 10%.
