Platinum-based translucent and fast casting liquid silicone rubber is a top choice for crafting detailed and durable moulds for epoxy resin projects. Its clarity and resilience make it popular among both professionals and hobbyists seeking high-quality results with minimal hassle.
Key Features and Advantages
This advanced silicone rubber boasts a translucent finish that enables close inspection of the casting process. The platinum cure system results in reliable curing, high mechanical strength, and excellent dimensional stability, making it suitable for both intricate and larger pieces. With a user-friendly 1:1 mixing ratio and a fast curing window of around 3 to 8 hours, it’s designed for efficiency without sacrificing quality. Once cured, the mould is flexible, non-stick, and ideal for repeated use with materials like epoxy resin, plaster, or cement.
- Detailed reproduction for small or complex items
- Reduced shrinkage over time compared to standard silicones
- Resistant to wear, maintaining integrity across multiple castings
Preparation Guidance for Casting Epoxy Resin
Preparing your platinum-based silicone mould is crucial for achieving the best results. Ensure the mould is thoroughly clean, dry, and free from dust or residue. Aggressive solvents should be avoided as they can degrade the mould’s non-stick properties. Mix the silicone rubber components in equal parts per the product instructions—such as with the Pure Mould – Translucent Liquid Silicone Rubber—and allow it to cure undisturbed for the recommended time. Before pouring resin, some users prefer lightly dusting the mould with a suitable release agent (if needed) for maximum longevity, though high-quality platinum-based silicones typically release resin easily on their own.
When This Matters
Using high-grade platinum-based translucent silicone is particularly beneficial when casting items where clarity, fine details, or reusability are important—such as jewellery, art pieces, or prototypes. The mechanical stability and smooth finish help reduce the risk of damage to intricate mould designs, ensuring consistent quality through many resin pours.
