40 shore A High Strength Liquid Tin Cure RTV-2 Silicone Rubber For Making Gypsum Sculpture/Statue Molds
Product Description
Silicone liquid rubber is called Tin cure silicone rubber which is
also called condensation-cure silicone mold rubber, these are
high-tear silicone mold rubbers that are known as the “work horse”
of the industry because of their performance and economy. Tin cured
silicone molds are used for casting wax, cement, gypsum, polymer
modified gypsum, resins, etc.
Application
MC Silicone RTV2 series are suited for reproduction of resin, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds, etc.

Instruction:
Architectural Moulding RTV-2 silicone rubber are generally named as two-part room temperature cure silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 2-4 hours. With resistance to deformation, high temperature, acid and alkali, and expansion. silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts.
Package:
Part A base silicone: 20kg,25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
Storage and Precautions of silicone liquid rubber:
RTV-2 silicone rubber for making art crafts, which is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
Why does the silicone rubber mold have few molding 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.
