Operation instruction of Addition Cure Moldable Silicone Rubber for Decorative Exterior Column:
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.
