RTV-2 condensation silicone features:
Silicone rubber condensation type with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. It is suitable for small products or fine and precision products which is difficult to demould. Condensaton silicone rubber is one of the products with the highest use level in the production of craftwork gifts and the shrinkage less than 0.2%.

RTV-2 condensation silicone applications
Condensation silicone(rtv-2)is mainly used in mold making for the manufacturer of products made of unsaturated resin, epoxy resin, polyurethane, cultural relic duplication, architectural decoration, resin crafts, lighting ornaments, candles, statues, model design, product exploitation etc.

RTV-2 condensation silicone 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.
