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 .

Technical Parameters

Model	Color	Mixing ratio (%)	Pot　life (mins, under 25℃)	Curing time	Hardness 　( Shore A　)	Tensile- strength 　(MPa)	Tear- strength (kN/m)	Viscosity （After A/B mixed ,mPa.s）	Shrinkage rate (%)	Elongation （%）
HY-E600	Translucent	1:1 or 10:1	30-40	4-5(hrs under 25℃) 20-30 (mins under 60℃)	0	3.5±0.5	5±0.5	3500±1000	≤0.1%	300%

Characteristics

＊An exceptional fluidity and good operability, easy to demold

＊Good　tensile and tear strength

＊Outstanding bubble releasing

＊Non-deformation

＊Low shrinkage

＊Aging resistance　,high temperature resistance (200℃)

＊Environmentally, food-grade




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
