Are These Resins Suitable for Moulded Plastic Objects?

Epoxy vs Polyurethane for Moulding

Epoxy resins, like “Trasparente” Multipurpose Epoxy, are known for their crystal clarity and high scratch resistance, making them well suited for artistic pieces, jewellery, and transparent components. Polyurethane resins such as IWhite Polyurethane Casting Resin cure rapidly and can capture extremely fine details, which is ideal for prototyping, model making, or objects that benefit from a quick turnaround.

Tips for Successful Resin Moulding

When selecting a resin for moulded objects, consider both the layer thickness required and the complexity of your mould. Epoxy resins are best used for casts up to around 2cm at a time. Polyurethane resins, on the other hand, are excellent where speed and minimal bubbles are key. Always measure and mix your components according to the product instructions and use protective gloves during preparation.

• Allow extra cure time for larger or thicker moulds.
• Ensure the mould is dry and clean before pouring to prevent imperfections.
• Colouring is possible: polyurethanes can be coloured before curing or painted once set.

When Resin Suitability Matters

Choosing the right type of resin is especially important when producing objects that require high detail, rapid production for prototyping, or a clear, decorative finish. These factors will help you match the resin’s properties to the outcome you expect—be it a showpiece, a functional prototype, or a crafted gift.
