RTV-2 silicone for PU resin&unsaturated resin crafts products.

RTV-2 mold silicone,RTV-2 silicone rubberare generally named two -component room temperature vulcanization RTV mold making silicone rubber, a kind elastic silicone rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion. mold making silicone rubber mainly applicable to make the silicone mould for cultural relic duplication,architectural decoration, resin crafts, lighting ornaments, candles, statues, model design, product exploitation, etc

RTV-2 silicone rubber is white or red flowing liquid with general hardness of 22-50A°after curing . If the customer wants to make large products and large size molds, the mold should be made of  RTV-2 silicone rubber with high hardness. On the contrary, if  the mold with fine and precision patterns , RTV-2 silicone rubber 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.

HY-638 RTV-2 silicone rubber is mainly used for toy gifts and craftwork gifts with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. RTV-2 silicone rubber is suitable for small products or fine and precision products which is difficult to demould. RTV-2 silicone rubber is one of mold making silicone rubber with the highest use level in the production of craftwork gifts and the shrinkage is up to 0.2%.
