        SILICONE RUBBER FOR CEMENT CASTING DESRIPTION:(LINK)
        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 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.

        SILICONE RUBBER FOR CEMENT CASTING APPLICTION :
        Both tin cure silicone and platinum cure silicone rubber are suitable for replicating the silicone rubber mold for cement products, as long as it with good tear strength and tensile strength. That means, it's also suitable for resin arts, polyurethane arts, culture relic ,ornamental plaster, garden sculptures, fiberglass animal,GRC,etc.

        SILICONE RUBBER FOR CEMENT CASTING FEATURES:
        1.High duplication times and no deformation
        2. Excellent 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

        SILICONE RUBBER FOR CEMENT CASTING 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 .

         

        SILICONE RUBBER FOR CEMENT CASTING NOTE

        Normally, different silicone should be chosen according to different product's features,for example :
