Condensation Silicone Rubber for Mold Making

Giftware molding materials--RTV-2 silicone rubber application

[1] giftware molding materials--RTV-2 silicone rubber application:
Giftware molding materials--RTV-2 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.

[2] giftware molding materials--RTV-2 silicone rubber features:

Giftware molding materials--RTV-2 silicone rubber, silicon rubber are generally named two -component room temperature vulcanization silicone rubber, a kind elastic silicone rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion

[4]giftware molding materials--RTV-2 silicone rubber instruction:
Silicone molding materials are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.
