Alkali Resistant High Strength Flexible White Silicone Liquid Rubber for Making Artificial Stone Molds
Product Description
RTV-2 silicone liquid 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.

Instruction of RTV-2 silicone liquid rubber:
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.
Why RTV-2 Silicone Liquid Rubber?
Economic Use
As the most stable polymer available, silicones offer superior reliability, excellent service life and reduced production costs.
Versatile Application
Silicone rubbers cure in deep sections as needed for electrical potting and encapsulating, casting rubber parts, arts restoration, general handy crafts, lost wax casting process, plaster forms, seals, stage decorations, statuettes and many more.
Chemical Resistance
Silicones resist acids, bases, solvents, chemicals, oils and water.
Package of RTV-2 Silicone Rubber
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.
