Tin-based silicones, also called condensation-cure silicones, are two-component materials which cure at room temperature(RTV)to flexible, high tear-strength rubbers. Tin cured silicones can be poured onto models or they can be made brushable by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance is required. Tin cured silicones can be used for casting polyurethane, epoxy and polyester resins, waxes, all gypsum products and low-temperature metals. Our tin-cured silicone systems are the most economical. They are best used for casting resins and low melt metals.
Description of rtv silicon rubber: Silicine rubber for manual moid is flowing liquid with consistant quality in whatever color. It consists of two components, wherein component a is silicone rubber, and component b is curing agent or vulcanizing agent. Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicone rubber, add 2-3% solidifying agent, and mix evenly for use. One mold pair can be solidified and formed in 2-3 hours. The formed mold can be used repeatedly without deformation and water shrinkage and with high temperature resistance, thereby providing fast duplication of the product with a product shrinkage 2. The 418 manual mold silicon is mainly applicable to manual molds and small number of product duplication. 25kg/drum, 200kg/drum

Step 1:preparing mold. Once you have your model to mould you need to build a box from wood/acrylic to contain the silicone and get a good covering over your model , the size and shape of this container is totally depends on shape of the model , remembering to leave plenty room surrounding the model so that you will have a strong wall thickness (at least 20mm) Note:small models can be cast in sourced containers like tins , ice buckets , cake tins, etc

Ferro Silicon Ferro Silicon has a melting point of 1200�¯�¿�½?�?�°C to 1250�¯�¿�½?�?�°C with a boiling point of 2355�¯�¿�½?�?�°C and Ferro Silicon contains about 2% of calcium and alluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.
We are exporter of Ferro Silicon. FerroChrome is a kind of Ferro alloy which is formed by Ferro and Chrome,it is an important alloy addition in steel making. Ferrochrome (Fe Cr) is an alloy of chromium and containing between 50% and 70% chromium.
