RAPID PROTOTYPE MOLDING SILICONE RUBBER DESCRIPTION:
ZEW RTV is a kind of two part silicone rubber in
addition cure or platinum cure type with mixing ratio of 1:1 .
widely used in rapid prototyping industry,
It can cure at room temperature as well as under heat .
It’s a kind of food grade silicone and mainly used for mold making.
RAPID PROTYPE MOLDING SILICONE RUBBER USAGES
Making molds for prototyping molding & casting;
Also suitable for making modls for chocolate, sugar, cakes, cookies, bread and so on
RAPID PROTOTYPING MOLDING & CASTING NOTES:
-Do not mix with liuqid condensation silicone rubber or even the tool which used for condensation silicone
-Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,
-Do not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem
