RTV silicone rubber for artificial stone molding


1. RTV Silicone Rubber for Artificial Stone Molding- Description:
E-640 is very suitable for making silicone rubber stone molds. It is featured with extremely low shrinkage, good fluidity and resistance to many kinds of chemicals; This material do not release any by-product with low molecular weight during its curing process, and it& acute;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 by-product of small molecules under certain conditions, (such as closed environment, high temperature). Known from our customer& acute;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.

2. RTV Silicone Rubber for Artificial Stone Molding- Advantage:
E-640 is also featured with low shrinkage and nearly nil viscosity, good fluidity; Without releasing any by-product with low molecular weight, and it& acute;s cured from top to bottom, from the inside and outside simultaneously. It is suitable for the products with medium size or big size.
