1.Applications of Silicon Rubber for Making molds:

molding Silicone rubber   can be used for  plaster crafts .

RTV-2 silicone rubber can be usd for molds making of cement crafts .

RTV-2 silicon rubber for  molding of  casting wax, gypsum, concrete or resins (urethane, polyester, etc. )

2.Features of Silicon Rubber for Making molds:

1) Excellent performance

2)High tear strength

3) Resistance to high temperature

4) Competitive price

5) Samples are available

3.Instructions of Silicon Rubber for Making molds:

Silicon Rubber for Making molds are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2-3% curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.
