Red Glow Phosphorescent pigment LB-WR

Everyglow® Red Phosphorescent Pigment

Our Red Glow Phosphorescent Pigment is an advanced Yttrium oxysulfide doped with Europium specifically engineered to emit a deep, striking crimson glow. Unlike common green or blue pigments, red phosphorescent pigment offers a unique aesthetic and high-contrast visibility, making it a favorite for safety markers, automotive accents, and high-end artistic applications.

Red phosphorescent pigment Key Features & Benefits

  • Rare & Distinctive Color: Produces a vivid red luminescence that stands out against standard safety colors.
  • Daytime vs. Nighttime Appearance: Typically appears as an off-white or pale red powder in daylight, transitioning to a deep ruby glow in total darkness.
  • High Performance: Formulated with rare-earth doped Europium to provide a more stable and longer-lasting glow than older zinc-sulfide alternatives.
  • Chemical Stability: Encapsulated versions available for use in water-based mediums to prevent oxidation and ensure longevity.
  • Heat Resistance: Red phosphorescent pigment stable at temperatures up to 500°C ( 930 °F ), making it suitable for plastic injection molding and high-heat coatings.

Red phosphorescent pigment Applications

1. Safety & Emergency Signaling

Used for specialized warning signs where red is the internationally recognized color for “Stop” or “Danger,” ensuring these symbols remain visible during power outages.

2. Automotive & Marine

Ideal for custom paint jobs, rim coatings, and dashboard accents. The red glow provides a sophisticated, aggressive look for high-performance vehicles.

3. Sports & Outdoors

Incorporated into fishing lures, golf balls, and camping gear to assist in recovery and visibility during dawn, dusk, or night activities.

4. Arts & Crafts

Popular for resin casting, jewelry making, and “lava” effects in furniture (river tables). It is highly effective when mixed with clear epoxies, acrylics, and glazes.

Usage Instructions & Tips

  • Mixing Ratio: For optimal results, use a ratio of 15% to 30% pigment by weight relative to the clear binder/medium.
  • Background Matters: Always apply over a white or reflective background. A dark background will absorb the glow, significantly reducing the visible output.
  • Avoid Grinding: Do not use a ball mill or heavy grinding equipment, as mechanical stress can break the crystal structure and “kill” the glow capability.
  • Charging: Red pigments require a stronger light source to reach full saturation compared to green. אור UV (blacklight) or direct sunlight is most effective for a quick charge.

Safety & Handling

  • Non-toxic and non-radioactive.
  • Avoid inhalation of fine dust; use a dust mask and eye protection during mixing.
  • Store in a cool, dry place in a sealed container to prevent moisture absorption.

Can red phosphorescent pigments be used in outdoor applications?

כן, red phosphorescent pigments can be used outdoors, but with important limitations compared to common green/blue strontium aluminate glow powders.

Key points for outdoor use

  1. Light resistance & weatherabilityMost red long-afterglow pigments are based on calcium sulfide / sulfide systems, which are less stable outdoors:
    • Easily affected by moisture, rain, and high humidity
    • Tend to darken, fade, or lose glow brightness over time under UV sunlight
    • Not as durable as green strontium aluminate pigments for long-term outdoor exposure
    • Use surface-coated / encapsulated red phosphorescent powder (waterproof, UV-stabilized)
    • Mix with UV-resistant resin, topcoat, or outdoor varnish
    • Avoid direct long-term soaking in water
    • Use in shaded or semi-outdoor areas for longer lifespanImprovement methods
      To use them outdoors:
  3. Suitable outdoor applications
    • Safety signs, emergency markers
    • Road marking, decorative paving
    • Architectural decoration, night signage
    • Crafts and outdoor artworks (with proper sealing)
  4. Summary
    • Can be used outdoors, but not ideal for long-term open-air exposure
    • With proper coating and protection, they work for medium-term outdoor use
    • For extreme outdoor durability, green/blue glow pigments are still more reliable
