Rtv-2 For Mold Making, Brand Name : TCC SILICONE

We are offeing rtv-2 for mold making:
-two-parts, flowable liquid silicon & curing agent.
-it gets cured at room temperature 250c within 3-5 hours.
-an exceptional fluidity and good operability, easy to be demolded.
-good tensile strength and tear strength, low shrinkage.
-suitable for both brushing and pouring methods of operations for medium & large sized molds making.
application:
silicon rubber for pu/poly resin products, unsaturated resin products, plaster, candles and gypsums crafts, toys, soap, statuary, concrete casting molds making, etc.
