Color to color thermal Dust is also often called color-color thermal powder, thermochromic pigment or heat sensitive pigment. In fact, it is a mixture of Color to colorless Thermal dust + ordinary color powder (usually we choose fluorescent pigment, which has weak covering power and will not affect the color of the temperature-changing pigment itself).
Definition:
Color A to color B thermal Dust = Color A to colorless thermal dust + Color B fluorescent pigment.
When the temperature is rising to a specific value(e.g. 35℃), Color A will disappear, and the base color B will show up.
Cold sensitive effect water cup
For example, when making a water cup with a cold-changing effect.
Blue color + yellow color = green color
Turkey blue thermal dust (color to colorless series) + yellow fluorescent pigment are mixed, and you can get the effect of yellow turning green.
When cold water is poured into a plastic cup with a yellow base(see the below picture), green will appear, covering the original yellow base. Thus, a magic effect of yellow turning green is achieved.
When the cold water is poured out, the temperature rises to the specified temperature. At this time, the green will gradually disappear until it returns to the original yellow base.
Through the disappearance and appearance of green, the effect of one color turning into another color is achieved.
Heat-changing water cup
Of course, if you need to make a heat-changing water cup. It is the opposite principle.
That is, if you need a temperature-changing effect of blue to green, you only need to use a mixture of blue thermal dust + green fluorescent pigment to achieve your goal.
Principle: At room temperature, the blue thermal dust will cover the green background of the cup. At this time, what you see is the blue effect.
When the temperature ＞ 45 degrees, the blue will disappear and become invisible. At this time, the green background will be displayed.
In general,
(Turns green when heated) Blue-to-green thermal powder = Blue thermal dust + Green fluorescent pigment
(Turns green when colded) Blue-to-green thermal powder = Green thermal dust + Blue fluorescent pigment
Of course, you can choose the finished product of our mixed color-changing temperature-changing powder and buy it directly.
The price is the same as the regular color-colorless thermal powder. Suitable for small goods production, saving time and effort.
You can also choose to buy our color-colorless thermal powder + fluorescent pigment and mix it yourself (we will give you technical guidance, it's very simple!). It is suitable for mass production, you can mix your favorite color, and save costs. (Because the cost of fluorescent pigment is much lower than that of color-colorless thermal powder.)
Finally: This Color to color thermal Dust is also divided into a reversible thermal dust (after color change, the original color can be restored) and an irreversible thermal dus (after color change, the color is permanently maintained).
