Product Description

                       Technical DateSheet

                 HY-E630 Addition Cure Mold MakingSilicone Rubber



HY-E630 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 . Its a kind of food grade silicone and mainly used for mold making.



HY-E630 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 and100 Gpart B(Or 100 G part A and 10 G part B)and mix them evenly.

Notes: Addition cure mold makingsilicon rubber istwo 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. Whats 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 causecross linking reaction, and no more further steps will be available.


Step 4: Pouring casting orBrushoperation

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 wont 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 notmix withliquidcondensation silicone rubber or even the tool which used for condensation silicone

Do not mix withorganic 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 toprevent uncure problem
