RTV-2 Silicon rubber applications
RTV-2 Silicon rubber is primarily intended for poly resin crafts, PU crafts, PU resin crafts, gypsum crafts ,unsaturated resin crafts, lighting and candles crafts ,plastic toy , stationery gifts crafts industry, a large statue Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
RTV-2 Silicon rubber features
RTV-2 silicone rubber is white or red flowing liquid with general hardness of 22-50A¡ãafter curing. Molding silicon 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.
RTV-2 Silicon rubber operations:
If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.
(Note: our company does not recommend you to add silicone oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demould.)
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.
