E640 is very suitable for making silicone rubbe stone molds. It is featured with extremely low shrinkage, good fluidity and resistance to many kinds of chemicals;

This material do not release any byproduct with low molecular weight during its curing process, and it's cured from top to bottom and from the inside and outside simultaneously, namely, deep curing. The E sereise platinum cured silicone will not have the problem of degradation, sticky mold surface caused by the existence of byproduct of small molecules under certain conditions, (such as closed environment, high temperature). Known from our customer's feedback, it is very convenient to make cement molds, and it is a high-quality silicone for construction industries. Further more, it can be applied to make multiple piece molds for products with complex design.
