like shinetsu addition cure moldmaking silicones for polyurethane molds  

Description

Our E640 addition cure moldmaking silicones is 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

Our E640 addition cure moldmaking silicones 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.

 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.
