How to dissolve thermochromic pigment
Q: How to dissolve thermochromic pigment?
A: Thermochormic pigment will not and should not dissolve in any solvent. Once dissolved, the micelle structure will be destructed and the pigment will lose its thermochromic colour switching effect. Instead Thermochormic pigment disperses in water and organic solvents. The use of polar organic solvents to mix the thermochromic pigment should be avoided e.g. methanol, ethanol, acetone, butanone …etc. Please avoid using polar solvents. The solvent we most frequently utilise to disperse thermochormic pigment is cyclohexanone
