Alkali Resistance RTV-2 Liquid Tin Cure Silicone Rubber For Making Concrete Artificial Stone Veneer Molds
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 of RTV-2 silicone liquid rubber
Decorations, stuccowork: castings, coiling roses, figurines, decorative candles, statuettes,
Renovation of architectural monuments: making moulds for monuments, archaeological fossils, etc.,
Ceramics: standards and moulds for artistic, home-based and industrial making of ceramic and porcelain products,
Artistic products: sculptures, masks, special decorative elements, figurines, bas-reliefs,
Technology: prototypes and components for leak tests and corrosivity checking, making moulds for technical and industrial applications (e.g. automotive components, audio-video equipment, household products),

Instruction of RTV-2 silicone liquid rubber:
How to use the silicone rubber to make a mold
Step 1: Prepare and clean the master piece. Please make sure your original moulds clean and dry.
Step 2: Mixing part A and part B evenly. Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Step 3: Vacuum degassing, this step takes less than 10 minutes. Otherwise, it will cause a cross-linking reaction, and no further steps will be available.
Step 4: Pouring or brushing. After released the bubble, we can pour/brush the silicone rubber on the master piece.
Package of RTV-2 Silicone Liquid 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.
