Operation instructions of RTV-2 Mold Making Silicone for PU Castings
1-Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
2-vacuum pumping
Without exception, this step takes less than 5-10 minutes. Take the silicone mixture to the vacuum chamber to degassing.
3-Pouring mold or block mold of silicone rubber
The pour molding is an easy way to make molds, it's Slowly and evenly perfuse the mixed silicone rubber into the square frame. After the cross linking reaction.
Storage and Precautions of Liquid Silicone for Moldmaking
