Description of cast stone statues mold making silicon casting

Our E630 mold making silicon castingis featured with almost nil shrinkage and perfect fluidity; Without releasing any  by-product with low molecular weight, and it's cured fully from top to bottom, from the inside and outside  simultaneously, so it will be deeply-cured. The E sereise addition cured silicone will not meet the problem of degradation or sticky molds because of the existence of by-product of small molecules under certain conditions, (such as closed, high temperature).it's very ideal material for moldmaking and casting, such as stone concrete molds, cement molds, statue molds, reproduction for crafts or toys, and so on. The cured mold can be reused for hundreds of times, without transformation and distortion. Its durability is so strong that it sells very well in the global markets. 

Typical Applications of cast stone statues mold making silicon casting

Our E630 mold making silicon casting can be used in not only the field of common RTV 2 part moldmaking silicone. As the vulcanizing reactions of addition cure silicone is fundamentally different from tin cure silicone’s, it has no problem of deep vulcanizing or reverse reaction, or other problem. Therefore, our addition cure silicone is particularly applicable for plaster silicone molds, cement product mold, other molds even with big size, and so on. It features with lower viscosity, high strength , good fluidity, so it can also be very suitable for the replication for the models with precision and complex pattern. From the following information, you will get a full view of its performance. 
 

Characteristics of cast stone statues mold making silicon casting

-almost nil shrinkage
-high chemical resistance to aggressive components of some types of resins
-good tear strength (this feature ensures higher resistance to wearing and shearing)
-high degree of precision in reproduction
-high dimensional stability over time and non-deformability
-high resistance to high temperature and aging(resist -60 to 200°C)
-excellent non-stick effect
-food grade silicone (environmental,odorless and nontoxic)

OPERRATING INSTRUCTION of cast stone statue mold making silicon casting

1.Stir part A and part B with right mixing ratio evenly. (E630# is 1:1) 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 .

 Frequently asked questions:

Why is the silicon mold oily? 
The molding silicone rubber itself doesn’t contain any oil, so it won’t be oily. If the mold is oily, it may be because you add the compound silicone oil( the compound of silicon oil and white oil). The white oil is not silicon oil but a kind of petrochemicals.

Twelve (12) months from date of shipment when stored at 24°C in original unopened packages.
