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 25 Deg.C. 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.
