For releasing the air bubbles, after mixing evenly, put the mixture into vacuum pumping for 3-5 minutes
Step 6 First layer
Evenly brush the first layer of mixed silicon rubber on the model. it should not be too thick
Step 7 Second layer
Brush the second layer of silicon rubber after the first one is cured. Normally the second layer should be 3-5mm, Cover a gauze or cloth on it when the second layer’s cross linking reaction goes on, and use a brush to avoid any interstices. Evenly brush the third layer of mixed silicon rubber on the gauze or cloth
Step 8 Outer molding
Way 1:pouring
Way 2: brushing
Package of RTV-2 Silicone Liquid Rubber
Part A base silicone: 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
