Careful Pigment Measurement for Fluorescent Resin

← Back to How to make fluorescent resin

Achieving a truly vibrant glow in fluorescent resin projects hinges on correctly measuring the pigment. Proper measurement not only ensures consistent, bright results, but also helps preserve the clarity and workability of your resin mix.

Recommended Pigment Ratio

For most fluorescent resin applications, it’s advised to add fluorescent pigment at a ratio of 20–30% by weight compared with the binder (resin). Using too much pigment can make the mixture overly opaque or affect curing, while too little may result in a weak glow. Always aim for this ratio to strike a balance between vividness and stability, especially when working with clear resins.

If you are new to the process, start with a 20% ratio and assess the effect after curing. You can always add more in future casts if you desire a stronger glow.

Steps for Accurate Measurement

• Weigh your resin first: Calculate the total amount of resin needed for your project.
• Measure pigment by weight: Weigh out 20–30% of the resin’s weight in pigment using a digital scale for precision.
• Mix thoroughly: Add the pigment gradually while stirring to distribute evenly and prevent clumping.
• Test on a small batch: Consider mixing a tiny test batch before committing to a full pour, as resin types and project sizes can affect the final appearance.

When Careful Measurement Matters

Precise measurement becomes especially important in projects where clarity, even colour distribution, and reliable glow effects are crucial—such as jewellery, safety markers, or detailed decorative pieces. Overloading pigment could hinder curing or dull the final finish, while under-measuring weakens the luminous effect. Choosing quality pigments like Fluorescent UV Pigment Powder will also help you achieve consistent results.
