Description
HY-E600 is a kind of two part silicone rubber in addition cure or platinum cure type with mixing ratio of 1:1 or 10:1 . 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.
Application
HY-E600 silicone rubber is mainly used for sex products, making molds of concrete stone,GRC,polyurethane products ; wax, candle decoration ; rapid prototyping and tyre molds; chocolate,candy and similar products .

Operation instructions
Step 1: prepare the original molds
Prepare an perfect original mold and clean it totally before operation .
Notes:Make sure your original molds and operation tool cleaned up totally to avoid uncure problem .
Step 2: Take 100 G part A and 100 G part B (Or 100 G part A and 10 G part B) and mix them evenly.
Notes: Addition cure mold making silicon rubber is two part flowing liquid , Pls follow the step strictly:
1.Weigh the two part exactly by electronic weight..
If any part not in exactly weight , it may cause changing of hardness , or even cause uncure problem.
2.Mix part A and part B evenly.
Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.
Step 3: Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause
cross linking reaction, and no more further steps will be available.
Step 4: Pouring casting or Brush operation
Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air .
2.For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush .
3. We suggest to set the silicone mold for another 12 hours after demould before put into large production .
Warm tips :
1. 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 liquid 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
