SILISIL RTV MF-Dura 30 — Molding / Mold Making (Shore A 30)
SILISIL RTV MF-Dura 30 is a two-component addition-curing silicone rubber from the SILISIL Moulding-Flex series. Its platinum-curing formulation produces a low-shrinkage mold with excellent detail reproduction, high tear strength, and a long mold life—the standard solution for professional mold making.
A Shore A hardness of 30 places the product in the category of soft silicones (flexible molds, skin simulation).
product benefits
- 2K addition system with a precisely calibrated mixing ratio
- Shrink-resistant and dimensionally stable even after prolonged storage
- High tear strength and tear propagation resistance
- Excellent detail reproduction, even at the microscopic level
- Long service life when installed properly
- Compatible with standard casting and impression materials
Typical applications
- Model and Mold Making: Casting of prototypes, models, sculptures, and museum artifacts
- Synthetic Resin Casting: Molds for Polyurethane, Epoxy, and Polyester Castings
- Decoration: Molds for concrete, plaster, and wax castings
- Food Molds: Silicone molds for chocolate, sugar, and baked goods (after appropriate certification testing)
- Industrial Casting: Handcrafted production molds for small-batch runs
- Prototypes: Fast, precise reproduction of master models for design and development
Processing and Mixing
- For the exact mixing ratio, pot life, and demolding time, please refer to the technical data sheet (TDS) on this product page
- Before use, stir both components separately and then mix them thoroughly in the specified ratio
- Degassing under vacuum (30–50 mbar) removes air pockets and improves surface quality
- Apply ideally at 23 °C and 40–60% relative humidity
- Contamination from sulfur, amines, tin catalysts, or PVC must be avoided in platinum-cured systems—they prevent curing
Storage and shelf life
- Store in the unopened original container at 5–25 °C, in a dry place and protected from direct sunlight
- Shelf life from the date of manufacture as specified in the TDS — typically 12–24 months
- Close tightly after opening
Included documentation
- Technical Data Sheet (TDS) in German, English, and French
- Safety Data Sheet (SDS) under REACH
- Batch certificate upon request
