Nerpa Fluorescent Pigments a.k.a. "neon" pigments

Bring neon effect to your work with our Fluorescent Pigments, formulated for use in both Stonelith and epoxy resin systems. Our fluorescent powders appear intensely saturated in ambient light and glow cleanly under UV (365–405 nm). The 10–60 μm particle size supports smooth dispersion with minimal speckling. To be used for adding saturated colours to your Stonelith and epoxy projects, as well as many other cases, including inlays, marbling, graphic details, etc.

What to expect:

100g jars: enough for multiple projects.
Daylight brilliance: High chroma, contemporary “neon” aesthetic without harshness.
Blacklight response: Clean fluorescence under UV lighting (or sunlight)
Versatile medium compatibility: Optimized for mineral-acrylic composites (like Stonelith) and two-part epoxies.
Seven curated hues: A balanced palette designed for clear primaries and striking brights.
These pigments are not glow‑in‑the‑dark. Needs light/blacklight to fluoresce.
Short‑term outdoor use is fine, but prolonged outdoor usage can cause pigment fading over time.

How to use:

Stonelith (mineral–acrylic)

Pre-wet pigment with a bit of Stonelith liquid (Part B) to make a smooth slurry, then blend into the base. Adding directly into the Stonelith mix is also acceptable, but it introduces air.
Starting load: 0.5–3.0 % of total mix by weight. Increase for higher opacity. Mix gently to limit air; de-bubble with a vacuum chamber or by tapping the mold. Vibrations are very effective in deaerating the Stonelith-pigment mix.

Epoxy Resin

Disperse into Part A first (to save working time when the hardener is added), then add Part B. 3-5 minutes of gentle mixing is required to wet the pigments fully.
Starting load: 0.1–1.0 % by weight. Lower loads (~0.05–0.2 %) keep translucency; higher loads tend to become opaque and slightly increase viscosity. Avoid using excessive shear forces to reduce bubbles. Always test a small batch to confirm saturation and cure clarity with your specific system.
