Liquid silicone rubber teach you how to make silicone molds
Material: use silicone rubber brand : Smooth-on Silicones, Wacker Silicone Rubber, Rhodia Silicones, Hongye silicone rubber , ACC Silicone Rubber
Application of liquid Silicone Rubber :
mainly applied for making various molds:
used to reproduce concrete or cement, gypsum, gypsum, architecture, decorative arts and crafts, big statue, cultural relic product, etc.
milk white two component silicone rubber for molding making 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.
Features of liquid silicone rubber:
RTV-2 Room temperature sulfureted silicon rubber for mold making is white or red flowing liquid with general hardness of 22-50A°after 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.

How to make silicone rubber mold :
1. Added with 1% of catalyst, Condensation silicone (for gypsum crafts) can still flow within 2.5 hours, mold can be released in 23 hours.
2. Added with 2% of catalyst, Condensation silicone (for gypsum crafts) can still flow within 1 hour to 1.5 hour, mold can be released in 15 hours.
3. Added with 3% of catalyst, Condensation silicone (for gypsum crafts) can still flow within 50-70 minutes, mold can be released in 10 hours.
4. Added with 4% of catalyst, Condensation silicone (for gypsum crafts) can still flow within 40-60 minutes, mold can be released in 4-7 hours.
5. Added with 5% of catalyst, Condensation silicone (for gypsum crafts) can still flow within 30-50 minutes, mold can be released in 3-6 hours.
