RTV Silicon Rubber for Concrete Mold Making
Condensation molding silicone rubber
RTV-2 mold making silicone rubber is generally named as two-part silicone rubber that vulcanizes
at temperature. Part A is a flowable liquid, part B is the catalyst.
Applications of Mold making silicone rubber for stone products:
Mold making silicone rubber for stone products is mainly used in toys,gifts,decoration,plate engrave, human replica, art crafts, resin crafts,poly resin crafts,unsatured resin crafts, candle crafts, plastic crafts,stationeries,plaster crafts and Buddhist statue crafts,etc.
Features of Mold making silicone rubber for stone products:
• Very good flowability
• High Shore A hardness (approx. 30)
• Excellent tear strength
• High elongation and flexibility
• Little rate of deformation and shrinkage
RTV830 can be used in not only the field of common RTV 2 part moldmaking silicone. As the vulcanizing reactions of addition cure silicone is fundamentally different from tin cure silicone’s, it has no problem of deep vulcanizing or reverse reaction, or other problem. Therefore, our addition cure silicone is particularly applicable for plaster silicone molds, cement product mold, other molds even with big size, and so on. It features with lower viscosity, high strength , good fluidity, so it can also be very suitable for the replication for the models with precision and complex pattern. From the following information, you will get a full view of its performance.
• High temperature resist,high tear resist

FAQ for Mold making silicone rubber for stone products:
Why the silicone mold just can be reproduced for a few times?
a.Adding too much silicon oil into silicon rubber .silicon oil is an additive which destroies the molecular weight of silicon rubber and reduce the tension and tear strength.
b.Using the silicon rubber a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to make molds for large sized products with simple designs. so we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.
