Low Shrinkage Addition Silicone For PU Moulds
Low Shrinkage Addition Silicone For PU Moulds Description :
Low Shrinkage Addition Silicone For PU Moulds are generally named as two-part addition silicone rubber that vulcanises at room temperature.Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity ,good operability,excellent physical properties and very low shrinkage. The mixing ratio between Part A and Part B can be 10:1 or 1:1.

Operation instruction :
1. Pls clear the model and tool totally before operation to prevent cure inhibition.
2.Weigh the two part correctly by electronic weight in two separate container .
3. Mixing the two part in 1:1/10:1 and stir part A and part B evenly in 2-3 minutes .
4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3
minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly
down the side of the mold frame so that less bubbles caused)
5. Enclose the product (the original model) with four plastic plates or wooden plates.
6. Clean your products and brush a layer of release agent(detergent or soap water) on
your product.
7. Pour the vacuumed mixture into the model frame from the side of the mold frame .
