Brief Introduction of Resin crafts RTV silicone rubber
Resin crafts RTV-2 silicone rubber is a two component material,and the silicone 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...

Extensive Applications of RTV-2 silicone rubber
MC RTV-2 silicone rubber for moldmaking can be applied in many objects mold making, since MC RTV-2 silicone rubber has good flow ability and medium hardness, and the silicone can cure at room temperature, thus it's a good material for duplication
RTV-2 Silicone Rubber can be used for artificial stone moldmaking.For example RTV2030,RTV2066 and RTV2088 silicone.
RTV-2 silicone rubber can be appliied in candle and soap moldmaking, such as RTV215 and RTV218 silicone.
RTV-2 silicone rubber can be used for plaster moldmaking, such as RTV2025,RTV2028 and RTV2030 silicone.
RTV-2 silicone rubber can be applied in the field of shoe sole moldmaking, for example, RTV3010 and RTV3015 silicone.
RTV-2 silicone rubber can be used for prototyping and electronic potting.
RTV920&RTV930 silicone rubber is suitable for resin moldmaking.

FOQ of RTV-2 Silicone Rubber for Mold Making
Why does the RTV liquid silicone rubber for molding have few mold making times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
