Imaging Systems ELECTROLUMINESCENT
PHOSPHORS
It is well-known in the industry that many phosphor pigments are
unstable because they are sensitive to moisture. Microencapsulating
these phosphors gives it an inert coating to serve as a protective
barrier against the environment or to
aide in light enhancement. Electroluminescent (EL) phosphors are
used to illuminate several products, such as:
- Automotive backlighting
- Exit signs
|
- Cockpit lighting
- Night vision apparatus
|
|
- Flat panel back lighting
- Glow in the dark products

 DYES AND COLORANTS
Microtek manufactures a microencapsulated
leuco dye ink for a specialty
graphic arts application. We also have experience in microencapsulating
various other dyes, pigments and colorant materials for many diverse
applications such as determining pressure forces in extruders.
COLOR INDICATING SYSTEMS
Thermochromic, photochromic, and glow-in-the-dark materials are
microencapsulated for producing various imaging and temperature
indicating
systems. These products have many applications such as recording
change of temperatures on food and beverage containers to producing
tee
shirt transfers that change color depending on temperature or level
of sunlight . Other applications could be used in manufacturing
processes to
record temperatures at specified time intervals.
