        BRONZE CASTING MOLDING SILICONE DESCRIPTION:
        Silicone for bronze casting is kinds of two-component condensation room-temperature curing liquid silicone rubbers,part A is silicone material ,part B is curing agent(catalyst),the mixed ratio is from 100:2 to 100:5 (large adjustment range of hardness),as it excellent tear strength ,low viscosity and many times repeating molds ,it can be widely used according to different purposes.

        BRONZE CASTING MOLDING SILICONE APPLICATION:
        It is perfect molding material.and suitable to make mold for bronze casting,Lost wax bronze ,concrete stone, cement casting , gypsum decorations, plaster product, resin craft ,clay casting ,soap mold,ceramic casting ,Casting for Statue,Buddha,Christmas ornaments,sculptures,figures etc

        BRONZE CASTING MOLDING SILICONE FEATURES:
        1.Excellent tensile and tear strength with high copy times 
        2.Good resistance to weather, temperature, aging, acid
        3.Favorable tension,resistance to deformation
        4.Good characteristics of easy-operation
        5.Various hardness with 20-40 shore A
        6.long shelf-time &lifetime

        BRONZE CASTING MOLDING SILICONE OPERATION:
        Step 1: prepare the original molds 
        Prepare an perfect bronze and clean it totally(the release agent can be detergent, soapy water and Vaseline)before operation .Take 100g part A and 2~5g part B strictly and mix them evenly. 
        *Notes:Make sure the bronze and operation tool cleaned up totally to avoid uncure problem .
        Step 2: Vacuum pumping
        Without exception, this step takes less than 10 minutes.(normally is 5munites) Otherwise, it will cause cross linking reaction, and no more further steps will be available.
        Step 3: Pouring casting or Brushing operation
        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 brushingoperation way.which can copy the pattern exactly .
        brushing way require high viscosity which won’t be easy to flow away and easy to brush 
        Step 4:Demoulding:
        After 35 hours later, can demould the silicone mold,It’s will be better for mold to demould after 24 hours
        Notes :The curing temperature and curing time can be adjustable according to the operation conditions.
