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's cured from top to bottom and

from the inside and outside simultaneously, namely, deep curing. The E sereise platinum cured siliconewill 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'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's cured from top to bottom, from the inside and

outside simultaneously. It is suitable for the products with medium size or big size.

3. RTV Silicone Rubber for Artificial Stone Molding- Applications:

E-640 can be used in the field of construction applications. Because the vulcanizing reactions of

addition cure silicone is fundamentally different from tin cure silicone’s, it has some characteristics

that the condensation cure type do not have, such as adjustable curing rate, being completely

environmentally friendly, and so on. Therefore, our platinum cure silicone is particularly applicable

for large stones molds, artificial stone molds, plaster and other architecture elements replication.
