Silicone Rubber for Mold Making features:
Silicone rubber RTV for mold making is white or red flowing liquid with general hardness of 15-40A° After curing. Molding silicone rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.
Using instruction:
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.
Storage and Precautions of RTV-2 mold making silicone:
RTV-2 mold making silicone, which is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
