Colour Pigment Powders
Metallic Pigment Powder gives resin proper depth, shimmer, and clean colour without thinning the mix or leaving weak, washed-out pours.
If you're tinting resin for tabletops, moulds, river pours or repair fills, this is the stuff that gives you control. Good pigment powders disperse cleanly, keep colour strength in small doses, and let you build anything from a solid pearl pigment finish to a subtle mica powder for resin effect. If you want crisp colour without overloading the mix, start here and pick the shade and finish that suits the pour.
What Are Metallic Pigment Powders Used For?
- Colouring epoxy resin for river tables, bar tops, and feature pours where you need depth, swirl, and a proper metallic finish rather than a flat painted look.
- Tinting moulded resin parts, casts, and decorative pieces where a dry resin tint is easier to control than liquid colourants and will not water the mix down.
- Building layered effects in craft and finishing work by combining mica powder for resin, pearl pigment, or resin glitter to create marbling, veining, and contrast through the pour.
- Adding glow in the dark powder to badges, inlays, signs, and feature edges where the job needs visible effect after lights-out as well as colour in daylight.
- Matching or enhancing repair fills on coated surfaces and resin projects where a small amount of pigment powder lets you tweak tone without remixing the whole batch.
Choosing the Right Metallic Pigment Powder
Match the powder to the finish you want and the resin you are actually pouring. That is what stops wasted mixes and dull results.
1. Metallic vs Pearl vs Glow
If you want strong movement and shimmer in a deep pour, go for metallic pigment powder. If the job needs a softer sheen, pearl pigment is usually the better call. If the piece needs an effect once the lights are off, you need glow in the dark powder rather than hoping standard colour will do the job.
2. Fine Powder for Clean Mixing
Finer pigment powders are easier to disperse and less likely to leave specks through clear resin. If you are doing detail work, moulds, or thin pours, do not pick anything too coarse or you will spend longer chasing clumps than pouring.
3. Dose Light and Build Up
Start light and add more. Too much powder can mute transparency, affect flow, and leave the finish looking overloaded. For small test mixes, a little mica powder for resin goes a long way, so prove the colour before tipping it into a full batch.
4. Think About the End Finish
If the resin is being polished back, choose a colour and effect that still reads once the surface is cut and finished. For edge fills and decorative panels, stronger shimmer works well. For subtle repairs, a dry resin tint or softer pearl pigment usually blends in better.
Who Uses These Pigment Powders?
- Joiners and furniture makers use metallic pigment powder in epoxy river tables, knot fills, and decorative boards where the finish needs depth without looking muddy.
- Decorators and surface finishers reach for pigment powders when producing feature coatings, sample boards, and small resin details that need a cleaner, more controlled tint.
- Sign makers and display fitters use mica powder for resin and glow in the dark powder for letters, inlays, and branded pieces that need to stand out under site or showroom lighting.
- Workshop makers and repair teams keep a few shades on hand for patching chips, voids, and cosmetic fills where a dry resin tint is quicker to fine tune in small batches.
The Basics: Understanding Pigment Powders
Pigment powders colour resin without adding extra liquid. That matters because you keep better control of the mix, the flow, and the finished look. Here is the simple version.
1. Dry Powder Instead of Liquid Tint
A dry resin tint adds colour without thinning the resin down. That helps when you need strong colour in small batches, detailed moulds, or pours where too much liquid additive can throw the mix off.
2. Mica and Metallic Effects
Mica powder for resin and metallic pigment powder do more than change colour. They reflect light through the pour, which gives you shimmer, movement, and depth that plain flat pigments do not.
3. Glow Powders Need Light Charging
Glow in the dark powder has to absorb light before it glows. It is best for inlays, edges, and details where the effect is meant to show once the room goes dark, not as a substitute for normal daytime colour.
Resin Accessories That Make Pigment Work Easier
A few simple extras save wasted mixes, patchy colour, and a load of avoidable clean-up.
1. Mixing Cups and Ratio Pots
Use clear marked cups so you can measure resin properly and see whether the pigment powder is actually dispersed. Guessing it in an old tub is how you end up with streaks and a batch you cannot repeat.
2. Stir Sticks and Mixing Paddles
You need a proper stir tool to get mica powder for resin and pearl pigment off the sides and out of the corners. Skimp here and the first half of the pour looks right while the rest goes weak or clumpy.
3. Test Moulds or Sample Boards
Always run a small test before a full tabletop or feature pour. It is the quickest way to check colour strength, shimmer, and whether your glow in the dark powder gives enough effect once cured.
Choose the Right Pigment Powder for the Job
Use this quick guide to match the finish to the pour.
| Your Job | Pigment Powder Type | Key Features |
|---|---|---|
| River tables and deep decorative pours | Metallic Pigment Powder | Strong shimmer, visible movement, good depth through thicker resin sections |
| Subtle sheen on moulds, casts, and panels | Pearl Pigment | Softer finish, cleaner highlights, less aggressive than heavy metallic shades |
| Inlays, signs, and feature edges | Glow in the Dark Powder | Charges under light, stands out in low light, best for details rather than full opaque colour |
| Fine colour control in small batches | Dry Resin Tint | Easy to dose lightly, does not thin the mix, useful for repairs and sample work |
| Extra sparkle in decorative pieces | Resin Glitter | Bold visual effect, catches light well, best used where texture and sparkle are part of the look |
Common Buying and Usage Mistakes
- Adding too much pigment powder too early can overload the resin and kill the clarity. Start with a small amount, mix it through properly, then build the colour up if needed.
- Choosing the wrong effect for the job wastes time and material. Metallic pigment powder is for shimmer and movement, while pearl pigment gives a softer finish and glow in the dark powder is for low light effect.
- Not mixing from the sides and bottom leaves streaks and patches through the cured pour. Scrape the cup properly and keep mixing until the colour is even all the way through.
- Skipping a test mix on a new resin system is asking for trouble. Different resins carry colour differently, so run a small sample first and check the cured result before doing the full pour.
- Using coarse decorative additives where a fine mica powder for resin is needed can leave a gritty or uneven finish. Match the powder grade to the detail level and thickness of the pour.
Metallic Pigment Powder vs Pearl Pigment vs Resin Glitter
Metallic Pigment Powder
Best when you want depth, swirl, and a proper reflective finish in epoxy pours. It suits river tables, statement fills, and decorative panels, but it can overpower small repair work if you go too heavy.
Pearl Pigment
Pearl pigment gives a softer sheen and a more subtle finish. It is the better pick for lighter decorative work, mouldings, and jobs where you want the resin to catch light without looking too bold.
Resin Glitter
Resin glitter is about sparkle rather than smooth colour movement. It works well in crafts, badges, and eye catching details, but for a cleaner professional finish across a full pour, pigment powders are usually easier to control.
Maintenance and Care
Keep Lids Sealed
Pigment powders need to stay dry. Leave the tub open in a damp workshop and you can end up with clumps that are a pain to break down in resin.
Store by Colour and Batch
Keep colours labelled and stored neatly so you can repeat previous mixes. If you are carrying materials between jobs, a case system like Makita MakPac helps keep small tubs together instead of rolling round the van.
Use Clean Tools Every Time
Dirty stirrers and contaminated cups muddy the colour fast. Keep separate tools for light and dark shades, especially when you are doing whites, pearls, or translucent effects.
Protect Stock in the Workshop
If you are keeping powders, resin, and additives in a shared unit, lock them away properly. A few Padlocks save you from missing stock and split lids after other people have been rooting through the shelf.

Metallic Pigment Powder FAQs
How do I ensure pigment powder is mixed evenly in resin?
Start with a small measured amount and mix it into the resin before the hardener if the system allows, or straight after combining if the manufacturer says so. Scrape the sides and bottom of the cup properly and keep going until there are no streaks, dry pockets, or clumps left. A clean flat stirrer works better than a quick lazy swirl.
Can mica powders be used for both epoxy and polyurethane resins?
Yes, mica powder for resin can be used in both, but do not just assume it will behave the same. Epoxy usually gives you more working time and makes it easier to judge the final effect, while polyurethane systems can move faster and may need tighter mixing control. If you are changing resin type, do a small test batch first.
Will metallic powders settle at the bottom of the resin pour?
They can if the resin is thin, the pour is deep, or the powder is heavy and poorly dispersed. In most normal pours, good mixing and the right resin viscosity keep the effect suspended well enough, but very slow cures can let some particles drop. If the finish matters, test the exact resin and depth before committing.
Does metallic pigment powder weaken the resin?
Not if you use it sensibly. Small doses for colour and effect are generally fine, but tipping in too much powder can affect flow, clarity, and sometimes the cure. The fix is simple. Dose lightly, mix thoroughly, and stop once you have the colour you need.
What is the difference between mica powder for resin and resin glitter?
Mica powder gives a smoother colour effect with shimmer running through the resin. Resin glitter is chunkier and more obvious, so you see individual sparkle rather than a blended metallic look. For cleaner tabletops and fills, mica is usually the better option. For bold decorative pieces, glitter has its place.
Can I mix different pigment powders together?
Yes, and that is often the best way to get a custom finish. Metallic pigment powder, pearl pigment, and small amounts of glow in the dark powder can all be layered or blended, but test first. Some combinations look great in the cup and go flat once cured, so do not risk a full batch blind.
