Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

We manufacture and supply figurines molding silicone rubber, sculpture molding silicone rubber, foundry molding silicone rubber, art casting silicone rubber, foundry casting silicone rubber, etc with best quality and price in China.
