Are Thick Resins Compatible With All Pigment Types?

The world of resin art is bursting with colour, but not every pigment works with every type of thick (high viscosity) epoxy resin. Ensuring compatibility between your resin and colourants is key for vibrant results and long-lasting artwork.

Understanding Pigment and Resin Chemistry

Thick resins, such as those designed for precise line control or layering, have a different formulation compared to thinner casting resins. This means not all pigments perform equally—certain additives can interfere with mixing, curing, or the final look. For instance, Art Pro Deluxe is specially formulated for resin art but is not suitable for use with water-based dyes or on moist surfaces, as this can affect clarity and cure.

Practical Guidance: Choosing the Right Colourants

When colouring thick resins, always select pigments or pastes expressly labelled as compatible with your specific resin type. Avoid water-based dyes, acrylic paints, or any additive that may disrupt the resin’s curing process. Instead, opt for high-quality powdered pigments, resin-specific colour pastes, or alcohol ink that matches your resin’s chemistry. Before starting your main project, do a small test piece to check for any issues with dispersion or cure.

When Pigment Compatibility Really Matters

For detailed art pieces where precision and colour separation are vital.
If seeking a glass-like finish and lasting vibrance, especially in glossy coatings or layered effects.
Where consistent, durable curing is crucial—such as display pieces or trays exposed to daily use.
