Photochromic Pigment

Photochromic Powders include Pigments (micro capsules in a powder pigment format) and Dyes in crystalline powder form.

Photochromic Pigment's Function:

They have been specially designed for use in non aqueous based ink systems and thermal resins.

Photochromic Pigment

Photochromic Pigments are photochromic microcapsules in a powder pigment form. They are specifically designed  for use in non aqueous based ink systems although their use is not limited to this. They can be used to formulate non aqueous based Flexographic, UV, Screen, Offset, Epoxy, and Gravure ink formulations (for aqueous applications we would recommend using a photochromic slurry). Photochromic powders are colorless in their inactivated state and become colored when exposed to an ultraviolet light source. They will respond to natural sunlight as well as artificial sources of 365nm “black light”.

Colors include Red, Yellow, Blue, Green,Orange,Sky Blue, Violet.

Photochromic Pigment's Technical Specifications:

Solids: 98% +/- 2%
Particle Size: <7 microns (97%)
Shelf Life: 24months

Storage and Handling
Photochromic Pigments are more sensitive to the influences of solvents, pH, and shear than many other types of pigment. It should be noted that there are differences in performance of the various colors so that each should be thoroughly tested before commercial application.
Photochromic pigments have excellent stability when stored away from heat and light. Store below 25oC. Do not allow it to freeze, as this will damage the photochromic capsules. Longterm exposure to UV light will degrade the photochromic capsules ability to change color. A shelf life of 12 months is guaranteed provided that the material is stored in a cool and dark environment. Storage longer than 12 months is not recommended. Consult product MSDS prior to use.......
