Mixing behaviour of thermochromic pigment with the ink and paints

Q: What is the ideal mixing behaviour of thermochromic pigment with the ink and paints for its application on the product surface?

A: To reach a significant colour thickness of thermochromic pigment (also photochromic pigment) on the product surface, the pigment content of 20-30% w/w in printing ink is recommended, whereas 15-20% w/w is suggested for paint and spray paint. Integrated into plastic product of 1.5 mm thickness, the thermochromic pigment content should be at least 1% w/w.
