Liquid rtv silicone rubber for sculpture molding feature of liquid rtv silicone rubber for sculpture molding Liquid rtv silicone rubber for sculpture molding is flowing liquid with general hardness of 22-50 a �� after curing with features: 1)low shrinkage 2)good operation 3)high tear and tensile strength 4)curing agent free 5)easy de-mold 6)high reproduction times 7)resistance to deformation and high-temperature, acid-alkali Operations of liquid rtv silicone rubber for sculpture molding If customers want to make large products and large size moulds, the mould should be made of silicone rubber with high hardness. On the contrary, if the mould with fine and precision patterns, it should be made of silicone with low hardness. The amount of the curing agent depends on the actual requirements of the customer.
