Model Making Silicone

1 Description

GC silicone mold rubbers are widely used to reproduce high-quality miniature and large-scale models at a relatively fast pace. Tin-cured (C-8 series) silicone mold rubbers offer great flexibility, chemical resistance and release properties. Popular product options is C-820/C-825/C-830.

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.
