Everyglow Phosphorescent Powder (Glow-in-the-Dark)
Phosphorescent Powder is a high-performance, light-storing material based on Strontium Aluminate technology. It is engineered to absorb energy from various light sources and re-emit it as a vivid, long-lasting glow in total darkness. Often referred to as “glow-in-the-dark powder,” this pigment is the industrial standard for fail-safe safety lighting and high-end aesthetic applications.

Phosphorescent powder Key Features & Performance
- Exceptional Luminance: Utilizing rare-earth doped strontium aluminate, Phosphorescent pigment offers up to 10 times the brightness and 10 times the afterglow duration of traditional zinc-sulfide powders.
- Self-Sustaining & Eco-Friendly: Recharges indefinitely using sunlight, fluorescent, or LED light. It is a “passive” light source requiring no electricity, batteries, or wiring.
- Safety & Longevity: Non-toxic, non-radioactive, and chemically stable. The material is designed for a functional lifespan exceeding 15 years.
- Versatile Integration: Easily mixed into any clear medium, including epoxy resins, acrylics, solvent-based paints, glass glazes, and plastics.
- Weather Resistance: Highly resistant to UV radiation and temperature fluctuations, making it suitable for both indoor and outdoor environments.

Primary Applications
1. Safety & Emergency Egress
Crucial for creating photoluminescent safety systems (PLSS), including exit signs, stair nosing, and path markers that remain visible during power outages or smoky conditions.
2. Industrial & Automotive
Used for high-visibility marking on machinery, tools, and automotive parts (rims, calipers, and interior trim). It provides both functional safety and a premium custom look.
3. Art & Architecture
A staple for resin “river tables,” glow-in-the-dark floor tiles, and mural art. It allows designers to create environments that transform visually between light and dark states.
4. Sporting Goods & Marine
Incorporated into fishing lures, hunting gear, and marine markers to ensure equipment recovery and user safety in low-light outdoor settings.
Expert Usage Guidelines
- The Transparent Carrier Rule: The pigment particles must be suspended in a completely clear binder. Any tint or opacity in the medium will block light from reaching the pigment, severely reducing the glow.
- Optimal Background: Always apply the pigment mixture over a white or reflective base. Dark surfaces absorb the light, while white surfaces reflect it back through the pigment, doubling the visible intensity.
- Avoid Grinding: High-shear mixing or grinding will fracture the crystal structure of the pigment, which destroys its ability to store light. Always stir the pigment in gently.
- Recommended Concentration: A standard starting ratio is 20% to 30% pigment by weight.
Storage & Handling
- Store in a cool, dry place in a sealed container.
- Moisture-sensitive: Avoid exposing non-encapsulated pigment to water-based mediums for extended periods.
- Safety: Use a dust mask and gloves when handling the raw powder to prevent inhalation or skin irritation.
