        ORNAMENTAL CONCRETE MOLD CASTING SILICONE DESRIPTION:
        It is a kinds of Two-parts silicone, part A is flowable liquid silicon, part B is curing agent/ catalyst , The mixing ratio of condensation cure silicone is normally 100:2~100:5, some from European and USA is 10:1.The mixing ratio of addition silicone is normally 1:1, 10:1, 9:1,and both of it can gets cured at room temperature 25℃ within 3-6 hours or heating curing .

        ORNAMENTAL CONCRETE MOLD CASTING SILICONE APPLICTION :
        Both tin cure silicone and platinum cure silicone rubber are suitable for replicating the silicone rubber mold for Concrete products, as long as it with good tear strength and tensile strength.  it's also perfect for cement , concrete stone, GRC and GFRC products’ mold making,such as the flower pot , fountain,Polyurethane Wood Imitation,Reinforced Plastic,Garden Decorations ,fiberglass product and other decoration industries.

        ORNAMENTAL CONCRETE MOLD CASTING SILICONE FEATURES:
        1.High duplication times and no deformation
        2. Excellent mechanical properties, in particular tear 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.It gets cured at room temperature 25℃ within 3-6 hours.
        6.Suitable hardness from 30 to 40 shore A

        ORNAMENTAL CONCRETE MOLD CASTING SILICONE OPERATION:
        Prepare the original mold:Weight silicone & curing agent according to the mix ratio recommended,than remember to stir 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.

        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 to demould after 24 hours
        Note: We suggest to set the silicone mold for another 24 hours after demould before put into large production .

        Ornamental Concrete Mold Casting Silicone NOTE:1.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.our company does not recommend that customers add silicone oil. If customers surely need quite soft silicone mold or molding for fine detailed and complex patterns products, 5%-10% silicone oil can be added to soften the mold for easy demoulding.)
        The proportions and reactions of the curing agent and the base silicone are listed as the followings:
          1. With 1% catalyst, the handing time is within 2.5 hours and silicone the mold can solidify after 8 hours.
          2. With 2% catalyst, the handing time is within 1 hour and the silicone mold can solidify after 6 hours.
          3. With 3% catalyst, the handing time is within 30 minutes and the silicone mold can solidify after 4 hours.
          4. With 4% catalyst, the handing time is within 15 minutes and the silicone mold can solidify after 2 hours.
        (Note: Above speculation is not fixed data, because we provide 5 types of catalyst with different curing speed)


        ORNAMENTAL CONCRETE MOLD CASTING SILICONE SHELF LIFE:
