Platinum Cure Silicone Rubber

Place of Origin: Guangdong, China (Mainland) Brand Name: RXD Model Number: RTV1515

Product Details

   This product is a rubber used in the manufacture of silicone rubber molds. It is generally called two-component  vulcanized silicone rubber, which has excellent fluidity and good handling properties. The 2% curing agent is added at room temperature, and the silicone rubber can be used in 30 minutes. In 4-6 hours, it will have an elastic silicon mold resistant to deformation, high temperature resistance, acid and alkali resistance. This silicone rubber is mainly used for the replication of molds and precision molds for polyethylene crafts, resin crafts, lighting, candles, etc.

Instructions of  liquid platinum cured silicone rubber

1-Take 100g of part A and add 100g of part B and mix the silicone rubber and curing agent evenly.

2-vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause , and no more further steps will be available

3-Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and evenly pour into the mixed silicon rubber into the square frame. After the cross linking reaction.
