Specialty-Chemicals: Lumilux offers luminescence products for a wide range of applications. Such as phosphorescence (long afterglow) and fluorescent pigments for long afterglow safety way guidance systems and safety signs, glow-in-the-dark toys, brand protection, authenticity markings, prevent forgery as well as for automatic processes.

Technical Data

Lumilux Technical Data

The relative luminosity and long afterglow properties of pigments are closely linked with their crystalline perfection, particle size distribution and the transparency level of individual crystals. Incomplete crystal formation causes cloudiness or mechanical damage to the crystals under high shearing forces and fragmentation under pressure, which reduces the level of performance.

Phosphorescence of larger particles is more intense than phosphorescence of smaller ones. However, Lumilux® long afterglow pigments are supplied in a range of defined grain size distributions to meet the demands of various applications. Finer grain size grades are not produced by grinding larger particles but are synthesized independently under special crystallizing conditions. As a result, this reduces the negative differential in luminance compared with larger grain size grades.

The light emission properties of inorganic luminescent pigments are closely linked to their crystal structure. To sustain brightness, the crystal structure must remain intact. Therefore destruction by mechanical forces, such as grinding or high shear force should be avoided.

Photoluminescent Pigments for Safety Applications
Lumilux offers luminescence products for a wide range of applications. Such as phosphorescent products (afterglow or glow-in-the-dark) for safety application. This types are long afterglowing pigments (zinc sulfide and alkaline earth aluminate) for phosphorescent safety product. As well as luminescent effects for toys and noveltys.

Pigments for safety applications must meet the minimum afterglow requirements of international standards. The relevant metric for these requirements is DIN 67510-1 regulation that is internationally recognized as the standard for testing.
Photoluminescent Pigments for Toys and Novelties
The relative luminosity and long afterglow properties of pigments are closely linked with their crystalline perfection, particle size distribution and the transparency level of individual crystals. We offer a wide range of Lumilux photoluminescent pigments for safety application as well as long afterglow pigments for toys and novelties, so we will find a luminescent product with perfect properties for each application.

Lumilux® effect pigments create dramatic luminescent effects in toy, novelty and artistic or theatrical applications. We offer a wide range of Lumilux® effect pigments in different colors.
Photoluminescent Masterbatch / Granulate
The relative luminosity and long afterglow properties of pigments are closely linked with their crystalline perfection, particle size distribution and the transparency level of individual crystals. We offer a wide range of Lumilux photoluminescent pigments for safety application as well as long afterglow pigments for toys and novelties, so we will find a luminescent product with perfect properties for each application.

Granulated pigment concentrates (master batches) simplify the use of pigments in an extrusion process. Master batch pigments help processors handle and disperse the pigments in their polymer matrixes.
