Description of Addition cure molding Silicone rubber
Addition cure molding Silicone rubber 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.
Features of Addition cure molding Silicone rubber:
Addition cure molding Silicone rubber is a two component elastomer cross-linking at room temperature. The polymerization can be accelerated by heat. The silicone components are delivered as liquids, which once mixed and cured transform into a transparent, elastic and resistant material. Polymerization occurs without formation of heat.
Applications of Addition cure molding Silicone rubber
Addition cure molding Silicone rubber 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.
Advantage of Addition cure molding 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)
*good fluidity easy for pouring operation ( in round 10000 cps )

Operation instruction of Addition cure molding Silicone rubber:
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 .
Notice : As our Addition cure molding Silicone rubber 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°C in original unopened packages.
PACKAGE: Packed in 20kg/pail+20kg/pail, 200kg/pail+200kg/pail.
