We offer liquid silicone rubber. description of liquid silicone rubber for mould making rtv-2 is a two-component room-temperature-vulcanizing (rtv-2) silicone rubber. Depending on its curing mechanism, two types of rtv-2 are available: "condensation" cure type and "addition" cure type. In general, rtv-2 silicone rubber is a two-component material, and the silicone rubber includes part a base silicone and part b ca30 curing agent. The part a base silicone and part b curing agent can cure at room temperature by a condensation reaction. These silicone materials can be cast into the cured silicone mold: plaster, polyurethane, pu, grc, cement, resin, polyester, wax etc. features of liquid silicone rubber for mould making 1. Good flow ability and long working time 2. Medium hardness 3. High tear and tensile strength 4. Easy de-mould from complex replica parts 5. Acid and alkali-resistance 6. Low linear shrinkage applications of liquid silicone rubber for mould making rtv2 silicone rubber series are suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, grc products, gypsum products, resin products, pu molds. Etc. one datasheet of liquid silicone rubber for mould making.

We offer rtv 2 silicone. various applications of rtv 2 silicones a: cultural relic duplication, architectural decoration, statues b: resin crafts c: lighting ornaments, candles d: plaster, gypsum, cement, concrete decorations f: model design, product exploitation, etc. storage and precautions of rtv 2 silicones rtv-2 silicone rubber 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. procedures of mould making by rtv 2 silicones 1. Clean and prepare specimen (apply consolidant, sealant, or release agent if necessary). 2. Build retaining wall around specimen. 3. Stir silicone base to loosen any settled material. 4. Decant desired amount of silicone into mixing container. 5. Mix in appropriate amount of catalyst. 6. Apply to specimen. 7. If reinforced mold is desired, gently press in gauze after pouring fist layer. 8. When cured, gently remove mold from specimen. 9. If needed, create rigid backing or jacket over mold with plastic, urethane foam, or plaster. 10. Remove backing material and mold. Store mold inside rigid backing.

We offer pourable mold silicone rubber . Features of pourable mold silicone rubber for shoe mold making: shoes mould making rtv-2 silicone rubber is a two-component material, and rtv-2 silicone rubber is consisted of part a silicone base and part b ca30 curing agent, and the silicone base and curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone mould: shoe mould making, sand casting etc. characteristics of pourable mold silicone rubber for shoe mold making 1. Good flow ability and long working time 2. Medium hardness stone mold making 3. High tear and tensile strength 4. Easy de-mould from complex replica parts 5. Acid and alkali-resistance 6. Low linear shrinkage instructions for pourable mold silicone rubber for shoe mold making 1. Make sure the surface of the original is clean and free of loose material. 2. Weight 100 part a base and 2 parts of ca30 curing agent in a clean container. 3. Stir part a base silicone before use thoroughly, as filler separation may occur upon prolonged storage. 4. Mix part a and part b evenly until the ca30 completely dispersed in the base. 5. Pour the mixed part a base silicone and ca-30 curing agent as soon as possible onto the original 6. De-mold after 24 hours, it is will improve the replicate times of silicone mold. note: it is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.
