RTV-2 silicone rubber is a two-component material, the silicone consists of Part A silicone base and Part B CA30 curing agent, and the silicone base and curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: shoe mold making, sand casting etc.
Specifications of RTV-2 Silicone Rubber for Shoe Mold Making
1. Good flow ability and long working time
2. Medium hardness
3. Easy de-mould from shoe mold
4. Low linear shrinkage
Applications of RTV-2 Silicone Rubber for Shoe Mold Making
RTV-3010/3015/3020 silicone rubber is suited for shoe mold, simple products, sand casting mold making, and shoe mold by pouring way.
