RESION Silicone Casting Rubber Shore A8 is a platinum-cure RTV-2 silicone rubber designed for producing highly flexible moulds for a wide range of applications. This silicone rubber is strong, extremely flexible, food-safe and produces moulds with excellent durability and outstanding detail reproduction.
Thanks to its simple 1:1 mixing ratio, this platinum silicone is easy to use and suitable for both beginners and experienced users. Shore A8 Silicone Casting Rubber is the softest and most flexible silicone in the RESION range and is recommended for highly detailed moulds and shapes that are difficult to demould. Shore A8 silicone rubber is also particularly suitable for manufacturing adult toys.
Shore A8 is the ideal choice when you need extremely flexible, highly detailed moulds or finished silicone products, including:
The very low Shore A hardness allows even complex shapes to be removed from the mould easily without damaging the mould.

The key technical properties clearly listed in one place.
The technical product category, such as primer, resin, hardener or cleaner. It explains the product's purpose and helps you find other products with a similar function.
Mixing ratio indicates how much of each component is needed, for example resin (A) and hardener (B). A ratio of 100:50 by weight means 100 grams of A to 50 grams of B; by volume you might use millilitres. Weight and volume ratios are not necessarily the same because the components may have different densities. Accurate measuring is important for proper curing.
Hardness describes a material's resistance to indentation. For silicone rubber and other elastomers, the Shore A scale is commonly used: Shore A 15, for example, is softer than Shore A 40. Harder plastics may be rated on the Shore D scale. The number belongs to its Shore scale and is not a unit like MPa; values on different scales cannot be directly compared.
The tasks a product is intended for, such as laminating, casting, bonding, sealing or protecting. Products intended for the same application can differ considerably in processing, curing time and final properties.
Density describes the mass of a material per unit volume. Values may be given in g/cm³, kg/L or kg/m³; 1 g/cm³ equals 1 kg/L. For example, one litre of a liquid with a density of 1.2 kg/L weighs approximately 1.2 kg. Density helps convert between weight and volume, but it can vary with temperature.
The period for which an unopened product remains usable under the specified storage conditions. Check whether the period starts from the manufacturing date or another date. Shelf life may be shorter after opening, especially for products sensitive to air or moisture.
Cure shrinkage describes how much a resin, adhesive or rubber becomes smaller as it cures. The value is usually given as a percentage (%) and may refer to volume shrinkage or shrinkage along one dimension; these are not the same. Shrinkage matters for casting accuracy and for limiting stress or distortion.
Curing time is the period a product needs to reach a specified stage of cure. It is usually given in hours or days, often at a reference temperature such as 20 °C. A product may be tack-free or safe to handle before reaching its full mechanical and chemical resistance. Film thickness and mixed quantity may also affect the time.
Working time is the period during which a product remains workable after mixing or activation, usually given in minutes at a specified temperature, often 20 °C. With reactive resins, the chemical reaction also continues in the mixing container, and larger quantities or higher temperatures can shorten this time. Working time is different from gel time and full curing time.
Heat resistance describes the temperature a material can withstand after correct processing and curing, usually expressed in degrees Celsius (°C). Continuous exposure is different from a brief temperature peak, and mechanical loading may also affect the limit. Heat resistance is not the same as the temperature at which the product can be applied.
Read the warnings and use appropriate protective equipment before handling the product.
