Application:
H5210/H5225 Liquid two component rtv silicone rubber for making shoe insole is a kind of addition cure silicone rubber, which specially used for making silicone chiropody's products, silicone gel foot health products, therapeutic silicone insole and silicone podiatry products, such as silicone insoles ,foot support insole, foot insoles, height insoles / heighten insole / silicone height increase pad, heel insole, orthotic insoles, shoe cushion, foot pad, toe spreader, toe cap, toe pad, heel spur, heel cups, heel insole, heel pad, shoe pad, Silicone Metatarsal, etc.
How to use:
Step 1: prepare and clean the prototype.You must make sure your original molds perfect.
Step 2: Take the silicone and catalyst as the ratio1:1 (part A:part B=1:1) ,mix the silicone rubber and catalyst evenly.
Step 3: Vacuum pumping
After mixed the silicone evenly, it is better to release the bubble by Vacuum pumping.
Step 4: Pouring cast or brushing cast
After released the bubble, we can pour/brush the silicone rubber on the prototype
