Introduction of Liquid Molding Silicone for Stone mold Casting
MCSIL2030 RTV-2 silicone rubber is a two component material, and it consist of Part A base silicone and Part B curing agent. When the two parts mix together and pour or brush on a object, the silicone base and curing agent can cure to be a silicone mold at room temperature; And 24 hours later, the silicone mold can be released from the object, and then the silicone mold can be poured into the following material to copy: Plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

7.Not oily, stable quality.
Applications of Liquid Molding Silicone for Stone mold Casting
RTV-2 silicone rubber for mold making can be used in the filed of reproducing cement molds, concrete, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds, prototypes, furniture, sculpture and architectural elements etc.
RTV-2 Silicone rubber can be used for artificial stone mold making. For example, RTV2030, RTV2066 and RTV2088 silicone.
RTV-2 Silicone rubber can be applied in candle and soap mold making, such as RTV215 and RTV218 silicone.
RTV-2 Silicone rubber can be used for concrete, plaster and gypsum mold making, such as RTV2025, RTV2028 and RTV2030 silicone.
Procedures of Liquid Molding Silicone for Stone mold Casting
1. Make sure the surface of the original is clean and free of loose material.Packing of RTV-2 Liquid Silicone Molding Rubber
