Is Pure Mould Suitable for Wax and 3D Resin Moulding?

How Pure Mould Works for Wax and Resin

Pure Mould 20sh silicone rubber is a translucent, platinum-cured silicone renowned for producing accurate and detailed moulds. It is compatible with hot waxes—ideal for candle making—and is also widely used for casting epoxy, polyester, polyurethanes, and acrylic resins. For those working with 3D printed items, it ensures that fine surface details are captured and maintained in your finished resin cast. The translucent formulation allows you to observe the fill and positioning, which is particularly useful with intricate designs.

Handling Shrinkage and Reliability

One advantage of Pure Mould silicone is its minimal shrinkage during the curing process, so your wax or resin reproductions maintain the integrity of the original design. Shrinkage is mostly noticeable only with larger castings; for typical small models or jewellery, the effect is usually negligible. Following recommended mix ratios and cure times ensures the best dimensional accuracy. A simple 1:1 mix and relatively short setting times make it suitable for both professional studios and hobbyists alike.

Practical Tips for Moulding with Pure Mould

• Ensure thorough mixing of the silicone’s two parts in a 1:1 ratio for consistent results.
• Allow adequate curing time (approximately 3–8 hours for Pure Mould), avoiding premature handling which could distort the mould.
• The rubber’s high mechanical properties mean moulds last over multiple uses with both wax and resin casting.
