4.Using instruction for Liquid RTV Silicone Rubber for Molds Making for concret ,resin, gypsum
Component A is white flowing liquid and component B is the curing agent.For example, take silicone rubber of 100g and add 2g curing agent for mixing evenly (silicone rubber and curing agent must be measured accurately).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.If you don't have vacuum machine, please add 1.2% or 1.5% curing agent so that the bubbles can bubble itself.Since the less curing agent you add, the slower the mould will curdle, the bubbles will bubble out itself.
