How to Choose the Best Pigments for Epoxy Resin Projects

Pigment choice can completely change the look of an epoxy project. The right pigment can give you rich colour, better depth, cleaner blending, and a more professional-looking finished pour. The wrong pigment can lead to poor dispersion, muddy colour, visible settling, or effects that do not match what you had in mind.

This guide explains what makes a pigment a good fit for epoxy, why particle size matters, and why pigments designed specifically for resin projects usually give better results than generic colourants.

What Makes a Pigment Good for Epoxy?

Not every colourant works equally well in resin. The best pigments for epoxy are the ones that mix cleanly, produce strong colour, and behave predictably during the pour and cure.

In epoxy projects, a good pigment should help you achieve the look you want without making the resin harder to work with. That means the pigment should disperse well, avoid a gritty or clumpy appearance, and stay visually consistent as the epoxy cures.

Why Particle Size Matters

One of the biggest factors in pigment performance is particle size. Fine pigments usually mix more evenly into epoxy and create a cleaner, more refined look in the finished pour.

When pigment particles are too large, they can be harder to disperse smoothly and may be more likely to settle or separate visually as the epoxy cures. That is one reason why fine pigments are often preferred for woodworking and resin art projects where colour consistency matters.

Why Fine Pigments Under 60 Microns Are a Strong Fit

Pigments with particle size under 60 microns are often a great choice for epoxy because they are fine enough to disperse more cleanly throughout the resin. That matters in clear pours, decorative colour work, river tables, serving boards, moulds, and any project where the visual finish is important.

This is also one of the reasons fine pigments are often better at staying visually suspended in the epoxy instead of dropping out as quickly as larger, heavier particles. While project conditions and resin choice still matter, fine pigment design gives you a better starting point.

Why Beaver Dust Pigments Stand Out for Epoxy

Beaver Dust Pigments were designed specifically for epoxy applications, with fine particle size under 60 microns as a key part of that approach. That finer sizing helps the pigments disperse smoothly into resin and makes them a strong fit for projects where colour consistency and suspension matter.

Compared with coarser pigment options, Beaver Dust Pigments are built to work more naturally in epoxy resin instead of fighting against it. The goal is cleaner colour, easier mixing, and better behaviour during cure for woodworking and resin projects.

In practical terms, that means Beaver Dust Pigments are designed to stay suspended better in epoxy and reduce the settling issues that can happen with larger particle pigments.

Where Good Pigments Matter Most

River Tables

In river tables, pigment quality affects the whole look of the pour. Fine pigment dispersion helps create more even colour and a cleaner final effect through the full resin section.

Charcuterie Boards and Serving Boards

Smaller projects often show pigment issues very clearly because the coloured epoxy sections are easier to inspect up close. Cleaner pigment performance helps these projects look more refined.

Mould Pours

Mould work often benefits from pigments that mix easily and stay visually consistent through the cure, especially when the resin section is meant to look clean and intentional.

Decorative Resin Projects

Artistic pours depend heavily on pigment performance. The cleaner the pigment behaves in the resin, the easier it is to get the visual effect you actually want.

How to Choose the Best Pigment for Your Project

1. Start with a Pigment Made for Epoxy

The easiest way to improve results is to use pigments designed specifically for resin instead of trying to force a general-purpose colourant into an epoxy project.

2. Pay Attention to Particle Size

Fine particle size usually gives you a better shot at clean dispersion and more consistent-looking colour throughout the project.

3. Match the Pigment to the Look You Want

Some projects call for bold solid colour. Others need something more translucent, more layered, or more subtle. Pigment performance should support the effect you are trying to create.

4. Think About Settling During Cure

If settling is a concern, it makes sense to choose pigments designed for better suspension rather than larger, heavier particles that can drop faster during cure.

Common Problems with the Wrong Pigment

• Poor dispersion in the resin
• Visible settling during cure
• Grainy or muddy-looking colour
• Uneven visual effect in clear pours
• Pigments that do not behave well in epoxy applications

Frequently Asked Questions

What are the best pigments for epoxy?

The best pigments for epoxy are pigments designed specifically for resin applications, with fine particle size, strong colour payoff, and good suspension characteristics.

Why does particle size matter in epoxy pigments?

Particle size matters because finer pigments usually disperse more evenly in epoxy and are less likely to create a gritty look or settle as quickly as larger particles.

What pigment size is good for epoxy resin?

Fine pigments under 60 microns are often a strong fit for epoxy projects because they are designed to disperse cleanly and work well in resin applications.

Can pigments sink in epoxy?

Yes, some pigments can settle in epoxy as it cures, especially if the particles are too large, too heavy, or not designed for the type of resin application being used.

Why use pigments made specifically for epoxy?

Pigments made specifically for epoxy are usually designed for better colour performance, cleaner dispersion, and better suspension in resin than pigments not intended for epoxy use.
