hy-e600 addition cure mold making silicone rubber
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 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 :
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
