Note for wet applications: Working with fine pigments (small micron size) such as this can clump in your formula. Experienced formulators will mix the pigment with a small amount of batch material in something like a mortar and pestle. Once that small batch is colored and smooth with clumps mashed out, it is then added to the larger amount of base material.

Photochromatic Pigments react to changes in light levels and are activated by Sunlight. Photochromatic pigments will not fade in UV light, as they are dependent on UV for activation. You will not see a color change with indoor lighting only UV (Sunlight). They have several industrial applications such as graphic art, plastics, invisible inks and paints. 

Photochromatic Dyes can be extruded, injection molded, cast or dissolved into an ink. Photochromatic dyes can be used in various paints, inks and plastics (PVC, PVB, PP, CAB, EVA, urethanes and acrylics). The dyes are soluble in most organic solvents. 

Due to the wide variations in substrates, product development is solely the responsibility of the customer. 

 Storage and Handling

Photochromatic Dyes have excellent stability when stored away from heat and light. A shelf life of excess of 12 months provided that the material is stored in a cool and dark environment. Do not let them freeze as this will affect

Photochromatic dyes are sensitive to UV degradation over time. The life expectancy of the dyes depends greatly on the matrix into which they are dissolved, the additives used to stabilize them, and the intensity and duration of UV exposure. 

Photochromatic dyes can withstand most standard mixing procedures. 

Heat

Photochromic dyes can be subjected to processing temperatures of 180 C to 240 C without degradation, for a short period of time. Thermal degradation is a function of the combination of time and temperature. The shorter the time and the lower the temperature, the less thermal degradation will occur.
