Description

DC-C Series is a kind of room temperature vulcanized silicone rubber in condensation type. It’s generally named as two part silicone rubber , Part A is a flowable liquid silicone, Part B is the curing agent (Tin catalyst) . It’s mainly used for mold making.

Application

DC-C Series silicone rubber is used for making molds of concrete stone, GRC, gypsum decoration, plaster ornaments, fiberglass products, polyester decoration, unsaturated resin crafts, polyresin crafts, polyurethane, bronze, wax, candle, and similar products.

Operation instructions

Step 1: prepare the original molds

Make your original molds perfect. fix it on a board. And fix the original mold on a board , then used four piece of board to enclose the original molds .

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

＊Notes:Mold making silicon rubber is a kind of flowing liquid ,it contains two parts. Part A is a kind of flowing white liquid and part B is the curing agent or catalyst .Pls follow the step strictly:

         1.Weigh the two part exactly by electronic weight. If not, for example add too much catalyst , the operation time will be too fast to operate ,which will cause inconvenience to operate .

         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 s est use pouring operation way, which will be very easy to operate and demould. Pourable silicone require low viscosity which will be easy to flow smoothly and easy to de-air .

        2.For delicate pattern products we s est 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 s es to set the silicone mold for another 12 hours after demould before you put it into a large production .
