Tin-cured silicone rubber is a commonly used RTV-2 silicone material in industrial silicone mold making. It is typically composed of a Part A base and Part B curing agent. By properly adjusting the ratio between the silicone and curing agent, one can have better control over working time and curing time to meet the requirements of different mold-making processes. In this article, we will analyze the results of different adjustments made to the silicone and curing agent ratio.
