Curing Time(h): 2~4
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.
