How do you use thermochromic pigment on fabric?
The thermochromic paint is already mixed with an acrylic binder so it can be painted or screen printed directly onto the fabric. Choose light coloured fabrics for this work. If you use dark fabrics you will not be able to see the colour change.
How much does thermochromic paint cost?
While lacking smoke, the heat-sensitive paint adjusts its coloring via pigments, changing color as the temperature swings. The whole paints costs $320 per liter, but it will only last four to six months, due to excessive damage from UV light exposure.
