Directions for use
- Carefully weigh components A and B according to the mixing ratio (100:3 by weight).
- Mix the components well (tip: use the two cup mixing method).
- Pour the silicone mass in a thin stream into the deepest part of the mould (pour into the mould, not directly over the workpiece, to avoid air bubbles).
- Allow the mixture to cure for at least 24 hours.
- For optimal properties, the mould can be post-cured in an oven (150 °C).

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.
- Silicone casting rubber
-
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.
- 100:3 (by weight)
-
Elongation at break indicates how much a material can stretch during a tensile test before it breaks. It is expressed as a percentage (%) of the original length. At 100% elongation, the material has doubled in length just before breaking. A high value indicates a high ability to deform, but not how much force is needed.
- > 480%
-
Tear strength describes the force needed to extend an existing tear in a material. For silicone rubber, this matters when a mould is frequently stretched during demoulding. The value is often expressed in N/mm (newtons per millimetre of specimen thickness) or kN/m. These units are equivalent: 1 N/mm = 1 kN/m = 1,000 N/m. Check the unit carefully: a value in N/m is therefore a thousand times smaller than the same number in N/mm. Specimen shape and test method also affect the result.
- > 31 kN/m
-
Tensile strength is the maximum tensile stress a material can withstand during a tensile test before failure. It is usually expressed in MPa (megapascals) or N/mm² (newtons per square millimetre); 1 MPa = 1 N/mm². Under comparable test conditions, a higher value means greater resistance to tension. In composites, fibre orientation also affects the result.
- 4.9 MPa
-
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.
- 3-5 hours
- Net contents
- 10 kg, 1 kg, 5 kg
-
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.
- Approximately 30-40 minutes
-
Food contact suitability means that a material may come into contact with food under specific, defined conditions. This suitability does not automatically extend to every application.
- Food type: for example water-based, acidic or fatty foods.
- Contact time and temperature: brief contact may have different requirements from long-term storage or contact with hot food.
- Processing: correct mixing ratio, full curing and any required post-curing may be conditions of approval.
A fully cured or odourless product is not automatically food-safe. Check the manufacturer's declaration or technical documentation for the permitted use.
- No
-
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.
- Up to 250 °C
