Using Instruction:

Component A is white flowing liquid and component B is the curing agent. For example, take silicone rubber of 100g and add 2% curing agent for  mixing evenly. After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame.

Note: the product is used for pouring or brushing technique. That is to say, fix the product or sole model to be duplicated onto a plane plate, then enclose the plane frame with wooden plates to prevent the leakage of the silicon , mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model, then brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried.
