Products Details

Addition cure silicone is a kind of two part silicone rubber in addition cure or platinum cure type with mixing ratio of 1:1. 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.

TDS of 6 series of Silicone Rubber:


*An exceptional fluidity and good operability, easy to demold *Good tensile and tear strength *Outstanding bubble releasing *Non-deformation *Low shirinkage *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 avoide 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 sugges to set the silicone mold for another 12 hours after demould before put into large production .

1.Why does the silicone mold get burnt out?

This consequence happens only because you have left out the important notes when using unsaturated resin materials to produce your products. The unsaturated resin produces great heat when added the curing agent. So you must demould the product within 3 minutes to avoid this problem.

2.Why is the tear strength of the silicone mold weak?

In order to reduce the viscosity of silicone rubber and pursue a good quality, you may add a lot of silicone oil into the silicon rubber when making molds. In fact, it might have just the opposite effect. The tension and the tear strength will be reduced badly with the addition of silicon oil. And the silicon molds will be in a weak and flimsy manner.

3.Why is the appearance of the finished mold striate and unsmooth?

It is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation.So when you make silicon molds, firstly you should polish the product, spray the mold spray evenly on the product. In this case, the problem can be avoided.
