Product Description Product DescriptionGTSIL-T Series silicones are two compounds, liquid, tin cured silicone rubber that have exceptional tear strength and working properties, cured in room temperature. A range ofmaterials can be casted into the cured silicone molds : plaster, gypsum, concrete , wax, polyurethane ,polyester resin are typically used.FeaturesOutstanding release propertiesHigh flowability and long working timeHigh tear strength & tear strengthHigh elasticity, for easy removal of complex replica partsCan add thixotropic for vertical surface application Technical Datasheet Model CodeGTSIL-T05GTSIL-T10GTSIL-T15GTSIL-T20GTSIL-T25GTSIL-T30GTSIL-T35GTSIL-T40Hardness - Shore A04-1608-1014-1618-2223-2728-3225-2736-40Viscosity - Cps12000-1600010000-1400012000-1600014000-1800016000-2000026000-3200022000-3500014000-18000Mixing Ratio - %2%2%2%2%2%2%2%2%Tear Strength - KN/m212-1619-2315-1819-2323-2728-3023-2722-25Tensile Strength - Mpa3-54-63.5-5.54-64-65-74-64-6Shrinkage - %0.3%0.3%0.3%0.3%0.3%0.3%0.3%0.3%Elongation - %420-530%400-500%450-550%450-550%450-550%350-500%350-500%350-500% ApplicationsGTSIL-T Series silicones are good for making molds for resin, polyester, pu, wax, plaster, gypsum, natural and synthetic cement ( artificial stone ),GRC, soap, etc….detailed applicationlike following:Art and decoration: soap, candle, aquarium decoration, crafts molds.Furniture: concrete ,GFRC furniture, artificial stone moldsArchitecture: column, fountain molds, architectural restoration.ADDITIONAL INFORMATIONReproduction of Vertical SurfacesIf a skin mold is required of a vertical object or surface and cannot be made by normal pouring techniques, the catalyzed mixture can be made non flowable by the addition of thixotropic agent.1. Prepare the original as described earlier.2. Brush the original with a thin layer of catalyzed mixture. Repeat the operation when the first layer has started to cure, to achieve a coating thickness of >2mm. Leave to cure atroom temperature until the material is tacky.3. Prepare a new catalyzed mixture of silicone and add 1% by weight of thixotropic additive and mix thoroughly until a paste consistency is reached. De-airing of the mixture is notrequired.4. Using a spatula, cover the coated original with the thixotropic coating until all undercuts are filled; leave to cure for 24 hours at room temperature.5. Construct a support mold using polyester resin or plaster and allow to set in contact with the silicone coating. Carefully remove the support mold. Peel the rubber off the originaland place in the support mold.Use at High TemperaturesSome molds produced from condensation cure silicone rubbers can degrade when exposed to temperatures above 150°C (302°F) over a period of time or when totally confined instorage at high ambient temperatures. This can result in softening and loss of elastic properties.Resistance to Casting MaterialsThe chemical resistance of fully cured silicone rubber is excellent, and similar to all condensation cure silicone elastomers. It should be noted however that ultimately, resins andother aggressive casting materials will attack silicone molds, changing physical properties, surface release and possibly mold dimensions. Molds should be checked periodically duringlong production runs.Shelf lifeTwelve (12) months from date of shipment when stored at 25oC in the original sealed packages.
