Description of RTV Silicone Rubber for mold making:
Mold making RTV silicone rubber, Liquid Silicone Rubber, RTV 2 Silicone Rubber is general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. Add curing agent of 2% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 4-6 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion. The silicone rubber is mainly applicable to mold duplication of poly crafts, resin craftworks, lightings, candles, etc. And fabrication of precision molds.
Features of RTV Silicone Rubber for mold making
Outstanding release properties
High Flowabilty and long woring time
Medium Hardness
High tear resistance
High elasticity for easy removal of complex replica parts
Low viscosity rtv silicone good for pouring mold making
