Product Description Brief Introduction of Liquid RTV-2 Silicone for Concrete Mold MakingLiquid RTV-2 Silicone 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...Procedures of Liquid RTV-2 Silicone for Concrete Mold Making1. Make sure the surface of the original is clean and free of loose material.2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.3. Stir Part A base silicone before use thoroughly, as filler separation may occur upon prolonged storage.4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base.5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original6. De-mold after 24 hours, it is will improve the replicate times of silicone mold.Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.Extensive Applications of RTV silicone rubber for concreteLiquid RTV-2 Silicone can be used in the duplication of cement molds, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds. etc. Technical parameter of Liquid RTV-2 Silicone for concreteItemRTV 2030ColorLiquid whiteCuring agentCA30Mixing ratio100:2 100:5Mixed viscosity25000 cpsWorking time30-40 MinutesCuring time4-6 HoursHardness28-30 Shore ATear Strength30 N/mmTensile Strength0.3 MPARelative density1.10-1.15 g/cm3Elongation at break480% Mold making
