EASY TO USE: Mix the thermochromic pigment powder with a clear base. It's recommended to add a small amount of powder at the beginning then add more gradually until the desired color is achieved. Please note that mixing generates heat as well which may currently change the color of the mixture, and be patient with the procedure. TEMPERATURE ACTIVATED: When heat is applied to the thermochromic microcapsule, the substance structure inside the microcapsule changes, and consequently its color disappears. When colling down, the structure of the internal substance of the microcapsule returns to its original structure and color. This thermochromic pigment powder changes at 88°F from 1st color to 2nd color; while it's cool down, the craft shifts to its original color.

RECOMMENDED CONCENCTRATIONS: For solvent/water based ink/paint: 3~30% w/w(25%); for plastics injection/extrusion: 0.2%~1% w/w(0.5%)
