Can IWhite Resin Be Coloured or Painted?

If you’re working with IWhite polyurethane resin for model parts, there are flexible options for achieving the look you want. Whether you’d like to add colour during casting or apply paint to finished pieces, IWhite makes customisation straightforward.

Tinting IWhite Resin Before Casting

IWhite polyurethane resin can be tinted while still in its liquid state. Simply add resin-compatible pigments or dyes to part A or the mixed components before pouring into your mould. Be sure to use only colourants designed for polyurethane to ensure a smooth blend and maintain the resin’s properties. Stir carefully for an even colour and do a small test if you’re after a precise shade, as colour intensity depends on the amount and type of pigment used.

Painting After Full Cure

After IWhite resin is fully cured – typically within about 30 minutes – it can be painted using standard acrylic paints. For best adhesion, lightly sand the surface to remove any shine and wipe off dust before painting. This approach allows for fine detail work, weathering effects, or layered finishes ideal for scale models or miniatures.

When Custom Colourisation Matters

Being able to tint or paint your resin parts is especially useful when working on custom models, prototypes, or dioramas where matching existing parts or achieving a particular aesthetic is essential. Colour flexibility lets you streamline assembly for display models or make assembly and repair work less noticeable.
