The preparation method of thermochromic powder from color to color mainly relies on the mixing of thermochromic powder and ordinary color powder.

(It is recommended to use fluorescent pigments, which have weak hiding power and have little impact on the effect of the thermochromic powder itself)

Principle: The principle of color mixing of thermochromic powder is the same as that of ordinary toner. You only need to add a small amount of ordinary color powder to the thermochromic powder. The key to this blending method is to control the amount of ordinary toner added, which usually only accounts for about 10% of the total toner.

It should be noted that during the preparation process, the thermochromic powder and ordinary toner should be fully mixed and evenly mixed to ensure the uniformity and stability of the color change effect. At the same time, care should also be taken to avoid the use of diluents or solvents that may have a negative impact on temperature-changing materials to avoid compromising their color-changing properties.

In addition, the color matching cannot achieve the effect of thermochromic powder itself, which is black. Lowering the temperature can achieve the effect of other colors. Black will cover the discoloration effect.

If the customer has samples, they can be sent to the factory for proofing directly.

Color matching effect: Through different color matching, various expected color changing effects can be obtained.

I will give you a photo (Yellow to Green thermochromic powder) as below to explain it.

This kind of Temperature changing effect from Yellow to green is made by mixing Yellow fluorescent powder and Turkish blue Thermochromic powder.

I will give you more examples:

Mixing red and yellow can result in a red-to-yellow effect (if you add a little more yellow, it will turn orange into yellow);

Mixing red and blue can produce a purple-to-blue effect;

Mixing blue and yellow can produce a green-to-yellow effect;

Mixing blue and green can produce a blue-to-green effect;

Mixing green and red can produce a brown-to-red effect;

Mixing yellow and red can produce the effect of orange to red;

Mixing yellow with blue can produce a green-to-blue effect.
