RTV-2 Two-Component Liquid Mold Silicone, Low Shrinkage & High Tear-Resistant Liquid Silicone, Special Raw Material For Crafts Re-Molding
This product is RTV-2 two-component room temperature vulcanized liquid mold silicone rubber. It features excellent fluidity, high precision for texture reproduction, low shrinkage and great tear resistance. Both pouring & brushing molding methods are available. Widely used raw material for molds of resin, gypsum, cement, candle crafts.
- Good fluidity for easy vacuum defoaming, perfectly reproduce tiny textures of master model;
- Low linear shrinkage, stable dimension, anti-deformation for repeated casting;
- High tear strength & elongation, avoid cracking during demolding for undercut designs;
- Room-temperature curing without heating; working time adjustable for different projects;
- Resistant to resin, gypsum, acid and alkali, achieve long mold service life;
- Custom hardness, color and viscosity available; pouring grade & thixotropic brushing grade optional.
