2. RTV-2 molding silicone rubber materials features description
RTV-2 Molding silicone rubber materials is white or red flowing liquid with general hardness of 22-50A° After curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with easy operation, non-deformation, high-temperature resistance, acid-alkali resistance and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.
3. RTV-2 molding silicone rubber materials operations
If the customer wants to make large products and large size molds, the mold should be made of mold making silicone rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of mold making silicon rubber with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; Contrarily, if molds requiring slower drying and demould, less curing agent is needed.
