Order MaxLume PLK-Y1 PLK-B1 PLK-B2 PLK-P1 PLK-W1 PLK-O1



MaxLume is a class of newly developed phosphorescent (glow-in-the-dark) pigments which are based on Strontium Oxide Aluminate Chemistry. They are drastically different from conventional phosphorescent pigments which  are either based on Zinc Sulfide or on radioisotopes for their self-luminous properties. 


         Afterglow period of ten times current ZnS based phosphorescent pigments.

         Activation by a wide wavelength band (200-450 nm) but best results are obtained with an activation energy under 350 nm;

         Initial afterglow brightness of up to ten times that of conventional phosphorescent pigments;

         Increase in luminescence and afterglow with longer activation time;

         Excellent weather and light fastness;

         Free of hazardous and radioactive substances

Note: A little bit of this powder does a very long way!  All you need is very small amount applied to a surface.

MaxLume was originally developed to satisfy the current and future needs of the clock, watch and the instrument dial industries, but soon it was found out that like many other new products, the application possibilities are almost limitless.

Applications include:
Clock & Watch dials
Electronic instrument dial pads    
Home appliances
Lighting apparatus and switches; 
Exit sign boards
Emergency signage and low level    lighting escape systems;
Aircraft and automobile dials and  Instrument panels;
Firemen's equipment
Military applications
Outdoor path marking
Camping equipment
Textile printing and textile fibers
Writing & printing inks
