LUMENTIFY
Application
Photoluminescent pigments for safety signage & escape route marking
In safety-related applications, one thing matters above all: a reliable afterglow duration – regardless of the carrier material.
Technology
Technical key points
-
Paints, plastics and coatings
The same pigment can be incorporated into safety paints, plastic profiles, films and floor coatings. Loading, layer thickness and a light substrate determine the glow effect.
-
Durability over the service life
The pigments show very little ageing. The SiO₂ coating makes the pigment hydrolysis-resistant, even in damp environments.
-
Orientation, not illumination
Photoluminescent markings make routes and edges visible in the dark; they do not replace a light source. They charge fastest under daylight or UV, more slowly under artificial light.
Raw materials
Suitable raw materials & processing
We supply the glowing building block – you process it further. For Safety & Escape Routes, these raw materials are suitable:
-
Pigments
Incorporation into safety paints, plastic profiles, films and coatings for guide lines, stair and edge markings.
-
Granules
Broadcast into floor coatings under a clear, walk-resistant top coat.
In practice
Typical use cases
- Escape route markings in buildings
- Safety markings on equipment and fittings
- Marking of emergency and hazard points
Why LUMENTIFY
For Safety & Escape Routes
Safety applications allow no compromise on afterglow duration – we help you select the material that reliably meets these requirements.
Material
Material data at a glance
Key data of our glow pigments. How brightly a product glows in the end depends on carrier, layer thickness, loading and excitation – which is why we clarify this together through sampling in your own system.
| Material | Europium/dysprosium-doped strontium aluminate, inorganic |
|---|---|
| Surface | SiO₂-coated and therefore hydrolysis-resistant – even permanently in water |
| Thermal stability | Glow pigment 1,100–1,200 °C; from approx. 150 °C use only untinted pigments (light, whitish daylight colour) |
| Glow colours | Natural green (base shade, brightest), blue-green, untinted blue; tinted and weaker: blue, violet and further shades; white for a very white daylight colour |
| Afterglow duration | Natural green, blue-green, blue: more than 10 hours in total darkness, as a faint glow after 1–2 hours |
| Excitation | UV content (daylight, UV from 365 nm) charges fastest, artificial light more slowly |
| Guide loading | 15–20 % relative to the carrier material, 30–50 % in opaque carriers |
| Ageing | very little ageing |
