Can Polyform Casting Resin Be Coloured or Dyed?

← Back to What resin does Games Workshop use?

When you’re planning a casting project, the ability to achieve a specific colour can be crucial. Here, we look at whether Polyform casting resin can be coloured, and what your options are if you need coloured results.

Is Polyform Suitable for Colouring?

Polyform is a beige polyurethane casting resin designed for rapid prototyping and detailed model making. It is not suitable for use with dyes or colourants, meaning you cannot tint or colour the resin itself before casting. Any attempts to add pigments may affect the performance and finish of the resin, leading to inconsistent results. If your project requires a particular colour, you’ll need to consider an alternative casting material or apply surface finishes after demoulding.

Alternatives for Coloured Castings

If you require the look of coloured resin straight out of the mould, consider switching to a product formulated to accept pigments or dyes before curing. For example, “IWhite” Polyurethane Casting Resin can be coloured in its liquid state and is also suitable for painting once cured. This can offer more flexibility for hobbyists or professionals seeking customised hues in their finished pieces.
