Craft Resin 4 kg Platinum Silicone for Mould Making is a firm, durable 30A silicone designed for larger moulds, repeat casting and multiple mold making projects. The Shore 30A hardness provides excellent shape retention and support, making it suitable for larger trays, sculptures, decorative pieces and structured moulds with straighter walls. This two-part platinum cure silicone rubber mixes at a simple 1:1 ratio, while the larger 4 kg size provides more material for bigger moulds, multiple casts, workshops and frequent mould-making projects.

  • Easy 1:1 mix by weight - simple to measure, mix, and pour for smooth, consistent results with less mess and less guesswork.
  • Low-viscosity formula - flows easily into fine details and helps reduce trapped bubbles for cleaner surfaces and more accurate moulds.
  • Firm 30A silicone for strong, shape-stable moulds - ideal for projects that need more structure, support, and reliable shape retention.
  • Captures fine detail - reproduces textures, edges, and small features for clean, professional-looking results.
  • Fast room-temperature cure - cures in around 4 hours, helping you move from mould making to casting faster.
  • Low-odour formula - more comfortable to use indoors and suitable for a wide range of mould making applications.
  • Ideal for resin casting, candles, plaster and DIY projects - a practical choice for work where durability, detail, and repeated use matter.

The 4kg 2 part liquid silicone rubber is ideal for larger casting projects.
