HY- E642 Addition Molding Silicone
(for gypsum mold, tyre mold, food grade mold.etc.)
Description of Addition Molding Silicone:
HY- E series 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 (10:1),mainly be suitable for making molds application.
Applications of Addition Molding Silicone:
HY- E series addition molding silicone could be mainly used for making concrete stones, wax molds, PU molds, resin molds, gypsum casting, candle molding and chocolate , candy and any other FDA food product mold making,prototyping etc.
Advantages of Addition Silicone Rubber:
*low shrinkage (less than 0.1% )
*high tensile and tear strength with high copy times
*easy for operation (mixing ratio at 1:1 /10:1)
*very good flow and easy for pouring operation
*Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
*Outstanding resistance to concrete

Operation instruction of HY-E Series Addition Silicone Rubber:
1. Please 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.
Warm Tips for Addition Silicone Rubber:
As our E-series silicone is platinum cure silicone, which is very easy to cause cure inhibition, so pls do remember thoroughly clean the model and tool before operation. Besides, pls avoid the liquid E-series silicone contact or mix with the following material, otherwise the silicone won’t be cured:
1. Liquid condensation silicone ( condensation silicone not completely cured or organic tin compounds )
2 .Sulphur, sulfide and sulfur rubber materials.
3. Amine compounds as well as contains the amine materials.
4 .Pewter solder flux.
Shelf Life of Addition Silicone Rubber:
8-10 months when stored under 24°Cin original unopened packages.
Package of Addition Silicone Rubber:
If ratio is 1:1 :Packed in 20kg/pail + 20kg/pail and 200kg/pail + 200kg/pail.
