Addition Molding Silicone E642
Description
Addition molding silicone is generally named two-component 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.
Applications
Addition molding silicone could be mainly used for Rapid Prototyping
• Fluid moulding silicone designed for casting polyurethane, epoxy and polyester resins as well as wax and polyurethane foams.
• Casting of Plaster or Concrete
• High Temperature casting
Advantage
* Low shrinkage (less than 0.1%)
＊high tensile and tear strength with high copy times
＊easy for operation (mixing ratio at 1:1 )
＊good fluidity easy for pouring operation ( in round 10000 cps )

Operation instruction of HY-E Series molding silicone:
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 .
2. Mixing the two part in 1:1 and stir part A and part B evenly in 2-3 minutes .
3. 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)
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 vacuumed mixture into the model frame from the side of the mold frame .
Notice : 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: 8-10 months when stored under 24℃ in original unopened packages.
PACKAGE: Packed in 20kg/drum+20kg/drum, 200kg/drum+200kg/drum.
