Product Usage

tep 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 no cure 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 de-mould.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 . Brush 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 de-mould before put into large production .
Warm tips :
As addition cure silicone is a kind of platinum cure system , which will be easy to cause no cure 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 no cure problem

Product Storage

1.It is a kind of non-dangerous goods. This product should be sealed and placed in a cool and dry place which should keep from sunlight and rain .
2.Specially note that the silicone should not touch or mix with compounds including nitrogen, phosphorus, sulfur, tin, lead or metal organic acid.
3.Addition cure Silicone RTV-2 is an environmentally-friendly liquid silicone product, is not easy to burn which can be stored and transported as non-hazardous goods.
4. The shelf life is 12 months from the date of production.
It can be reused after reinspection when it exceeds the storage period.
