*Good operability, easy to demold

*Moderate hardness

*High tensile and tear strength

*Cure at room temperature

*Good flexibility

*High duplication times  


Step 1: prepare the original molds

Step 2: Take 100 G parts A and add 3G parts B and mix them evenly.

Step 3: Vacuum pumping

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 .  



1. Why should the silicone mold be reused only for a few times?
It can be due to the following reasons: 
a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight of silicone rubber and reduce the tension and tear strength.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs. 
(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
