Desprition of rtv liquid silicone rubber for concrete molds
E642# addition molding silicone is generally named two-components silicone rubber, Part A and part B. It features an exceptional fluidity and good operability. The mixing ratio is 1:1,mainly be suitable for making molds application.
Q642 addition cure silicone rubber is mainly used for molds making for food grade products. And it is also develop to solve the problem of not lighting of the candles and the problem of sticky and white stains on the surface of cement & stone products.
OPERRATING INSTRUCTION of rtv liquid silicone rubber for concrete molds for garden:
1.Stir part A and part B with right mixing ratio
evenly. And get the mixture for vacuum-
pumping. (If there is no vacuumizer,you can just pour the mixture slowly from the corner so that less bubbles caused).
2. Enclose the product (the original model) with four plastic plates or wooden plates.
3. Clean your products and brush a layer of release agent(detergent or soap water) on your product.
4. Pour the mixture with correct mixing ratio into the model frame.
After about 2-4 hours, when the silicone cured, get out the original model, and there you get a finished addition cured silicone mold .
