² Features of rtv2 silicone rubber
1. Good characteristics of easy-operation
2. Light viscosity and good flowability
3. Low shrinkage
4. Ecellent telsile and tear strength
5. Favorable hardness
6. High temperature resistance, acid and alkali-resistance and ageing resistance
² General Description of liquid silicone rubber for fake stone
rtv2 silicone rubber is general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 2-3 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.
² Operation of liquid silicone rubber for fake stone
1. deal with original moulds
2. brush on release agent
3. correct weigh accoring to mixng ratio
4. stir the two component evenly
5. vacuum-pumping
6. pouring

² Frequently asked questions of liquid silicone rubber for fake stone
1. Why should the silicone mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.
(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
