liquid condensation silicone rubber for pouring mold making
Applications of liquid condensation silicone rubber for pouring molds
silicone could be mainly used for making concrete stones, precision molds, PU molds, resin molds, gypsum casting, candle molding,for life casting, fabric finishing, seal for electronic components and solar circuit board, trademark decoration. etc.
Descriptions of liquid condensation silicone rubber for mold making :
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.
OPERRATING INSTRUCTION :
1. Stir part A and part B with right mixing ratio (1:1) 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 .
SHELF LIFE:
Twelve (12) months from date of shipment when stored at 24°C in original unopened packages.
