Description of Silicone  Rubber For Prototype：   

          HY-Q642 is a ideal material for prototype, with the all the advantage of being transparent, easy demoulding, and it is also featured with low shrinkage and low viscosity, good fluidity, favorable transparency; Without releasing any  by-product with low molecular weight, and it's cured from top to bottom, from the inside and outside  simultaneously, so it will be deeply-cured. The Q series addition cure silicone will not have the problem of degradation or sticky molds because of the existence of by-product of small molecules under certain conditions ( closed, high temperature).it's very suitable for making transparent molds for many kinds of products, not only prototyping.

Advantage of Prototype Silicone  Rubber   

         Q-642 is also featured with lower shrinkage and low 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 transparent, so it is very favorable and convenient for customers to use it. It will not produce harmful substances during the molding process, completely food contact grade(FDA grade).

Applications  of Silicone  Rubber For Prototype：  

         Q-642 can be used in the field of liquid silicone prototype. As the vulcanizing reactions of addition cure silicone is fundamentally different from tin cure silicones, it has no problem of deep vulcanize or reverse reaction, ect problem. Our addition cure silicone is particularly applicable for rapid prototype, large stones molding, plaster and cement product replication, arts and crafts molding. It features with lower viscosity, high strength , good fluidity, can also be very suitable for precision complex pattern on the mother mold.
