Gypsum mold silicone

DESCRIPTION
        Gypsum mold silicone is perfectly featured with extremely low shrinkage and favoralbe viscosity, good fluidity;Without releasing any  by-product with low molecular weight, and it's cured from top to bottom, from the inside and outside simultaneously,so it will be deeply-cured. The E- sereise two part silicone will not meet the problem of degradation or sticky molds because of the existence of by-product of small molecules under certain conditions, (such as closed, high temperature). It is the first grade moulding rubber for the replication, which will definitely make your business much easier.  


APPLICATIONS
        This product can be used in gypsum mold making, including home projects, decoration elements, making concrete fountain mold, replication for cave art in Europe,gympsum crafts molding, buddaha statue molding, fossil molds and cast, Europe component moulding, making sandstone molds, building decoration molding and so on. As the vulcanizing reactions of addition cure silicone is fundamentally different from tin cure silicone's, it has no problem of deep vulcanize or reverse reaction.  




MAIN FEATURES
＊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 .  


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 not mix with liuqid 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
