Description
Condensation Cure Silicone Rubber, also call RTV-2 silicone rubber, for mold making is generally named as two-part silicone rubber in liquid form that vulcanizes at room temperature. It is mainly applied for mold making or duplicating for industries in pouring or brushing way, such as artificial stones, gypsum crafts, concrete products, GRC, GRG, GFRC, fireplaces, fountains, ornaments, resin crafts, art sculptures, decorations, PU, furniture molding, candle crafts, plastic crafts, Buddhist statue crafts, etc..
Features
1. Good fluidity, easy to drain bubbles, easy to infuse, easy to operate and easy to demould.
2. Fast curing at room temperature
3. High tensile and tearing strength, low linear shrinkage (《0/3%)
4. There are many times of mold reversal (for example: the number of copies of plaster products can reach 800-1000 times
5. Good weather resistance, high temperature resistance, acid and alkali resistance, aging resistance
Application
Mold Making----GRC, GFRC, Concrete, Stone, Resin, Plaster, Gypsum, Soap, Candle, Tire etc.
Electronic Potting---- LED light, PCB, PVB, Module, Wind Power Generator, Ballast, etc.
