        TERRACOTTA ARTS MOLDING SILICONE DESRIPTION:
        It is a kinds of Two-parts silicone, part A is flowable liquid silicon, part B is curing agent/ catalyst ,which gets cured at room temperature 25℃ within 3-6 hours or heating curing .This product is perfect for mold making,such as the Terracotta Arts, resin crafts, Buddhist statue crafts,ceramic statues ,etc.


        TERRACOTTA ARTS MOLDING SILICONE APPLICTION :
        It is condensation RTV-2 mould making silicone rubber, specially suitable for replicating the Terracotta Arts perfectly due to its high tear and tensile strength. That means, it's also suitable for resin arts, polyurethane arts, culture relic , soap arts,ornamental plaster, garden sculptures, fiberglass animal,GRC,etc.

        TERRACOTTA ARTS MOLDING SILICONE FEATURES:
        1.High duplication times and no deformation
        2. Excellenttear strength and tensile strength.
        3.Good fluidity and good operability and good for both pouring method and pouring method.
        4.Excellent flexibility and it’s easy to demould.
        5. High temperature resistance.
        6.All hardness from 20 to 40 shore A

        TERRACOTTA ARTS MOLDING SILICONE OPERATION:
        Prepare the original mold:Weight silicone & curing agent according to the mix ratio recommended(100:2 to100:5),than Remember to silicone & curing agent evenly, otherwise the silicon rubber will be partly solidified and bring problems 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.

        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.

        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 .

        Demoulding:After 3-5 hours later, can demould the silicone mold, It’s will be better (去掉for mold) to demould after 24 hours
        Note: We suggest to set the silicone mold for another 24 hours after demould before put into large production .

        TERRACOTTA ARTS MOLDING SILICONE NOTE1.The curing rate of this product is closely relevant to the temperature. The higher the temperature is, the greater the humidity is and the curing speed becomes faster.
         2.Users can choose the curing agent according to the weather condition, and adjust the amount of the curing agent in order to reach the appropriated curing rate. 
        3.Normally, different silicone should be choosed according to different product's features,for example :
        - For products size (20cm-80cm)
        with intricate designs, 20-25 shore A is suitable. 
        with simple designs, 25-30 shore A is suitable.

        - For products size (80cm-150cm)
        with intricate designs, 25 shore A is suitable.
        with simple designs, 30-35 shore A is suitable.

        - For products size (more than 150cm)
        with intricate designs, 25-28 shore a A is suitable.
        with simple designs, 35-40 shore A is suitable.
