Clear addition silicone rubber for prototyping mold making  

 

Product Description

1 Usage of Clear addition silicone rubber for prototyping mold making: 

HY-968 is a kind of addition cure high temperature resistance organic molding silicone rubber.It’s liquid with moderate viscosity and can be poured and brushed.The mold made out of the silicone and curing agent,which with high temperature up to 280-350°C,has dimension stability,low linear shrinkage, high viscosity,high tear strength . It’s a two-component material with mixing ratio of 1:1,and it’s used for mold making, prototyping etc.

 

2 Features of Clear addition silicone rubber for prototyping mold making: 

Silicone rubber will not release low molecule under the condition of crosslinking,so the volume will not vary,linear shrinkage will less than 0.1%;it does not subject to the thickness of the products, and can be cured deeply;it with high tensile and tear strength and anti-yellowy under high temperature of 200°C.

 

3 Applications of Clear addition silicone rubber for prototyping mold making: 

It’s applicable to make mold,development and design for mobile model, exquisite model,lead-zinc alloy crafts ,PU, epoxy resin,food molds and the products with low shrinkage. 

 

4 Storage and precautions of Clear addition silicone rubber for prototyping mold making  

This product is forbidden to mix with organic compounds of condensation cure silicone rubber,otherwise, the silicone rubber will not cure, and also should not mix with organic compounds containing S, P, N as well as metallic salt of organic acids. It also will cause this product cure uncompletely or not cure. The shelf life is about 6 months.

 Warm tips

As addition cure silicone is a kind of platinum cure system ,which will be easy to cause uncure problem ,so

Kindly follow the tips below :

*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
