Is thermochromic paint toxic?
The thermochromic pigments and our water-based paints and inks are NON-toxic products conform to ASTM 4236 standard. However, we recommend you to follow the general rules for personal protection – wear latex gloves and protective glasses. The thermochromic products should not be ingested!
What is thermochromic pigment made of?
Thermochromic materials are generally organic leuco-dye mixtures, composed by the color former, the color developer, and the solvent. The color former is usually a cyclic ester and determines the base color. The color developer is a weak acid and produces the color change and the final color intensity.
What is heat sensitive paint?
Also referred to as thermochromic paint, heat-sensitive paint contains pigments that change color according to changes in the surrounding temperature. There are two main types of these pigments: leuco dyes and thermochromatic liquid crystals.
What is significant about thermochromic pigments?
Thermochromic materials change colour at specific temperatures. Typically, they are incorporated into a special ink and printed onto plastic films to create thermometers or temperature indicators. The thermochromic pigment in the Smart Colours system is made up as a liquid paste compatible with any acrylic media.
Are color changing mugs microwave safe?
is this item microwave safe? Answer: Yes it is.
Is thermochromic material safe?
As for inorganic reversible thermochromic materials, though they have good optical and thermal resistance and can be manufactured conveniently, their color variation is limited. More importantly, they are highly toxic and corrosive.
What are the disadvantages of thermochromic pigments?
The main pitfalls too often encountered are the sensitivity to ultraviolet, the low coloring power, the limited thermal resistance (200-240 ° C), the loss of properties during the formulation and / or the industrial process, the toxicity of certain elements components …
How does thermo sensitive ink work?
Thermochromic paints use liquid crystals or leuco dye technology. After absorbing a certain amount of light or heat, the crystallic or molecular structure of the pigment reversibly changes in such a way that it absorbs and emits light at a different wavelength than at lower temperatures.
How does a thermochromic thermometer work?
Thermochromic inks or dyes are temperature sensitive compounds that temporarily change colour with exposure to heat. This produces an aqueous slurry or concentrate which changes from colour to colourless as the temperature rises , and with decreasing temperature the colour returns.

What are the advantages of using thermochromic materials?
The main advantage of thermochromic paints and coatings is their dynamically variable performance, acting as cool coatings in the summer and as absorptive materials during the winter.
What happens if you put a color changing mug in the dishwasher?
When you put them in the dishwasher the water is HOT… They are definitely NOT dishwasher safe. The paint will either start peeling off or it will start fading so that the “hot” image is always visible, even when the mug is not in use.
How does color change in thermochromic materials?
Thermochromic materials change reversibly their color by a temperature change. Color transition is due to a change in crystalline phase and structure [11]. Thermochromic materials are generally organic leuco-dye mixtures, composed by the color former, the color developer, and the solvent.
What kind of paint do you use on a heat changing mug?
The paint they coat the heat changing mugs with is called heat-sensitive paint – a paint that is sensitive to changes in temperature. Heat-sensitive paint is used in a variety of things, including mugs, baby bottles, kettles, car engines and much more.
How do color-changing mugs work?
In essence, thermochromism is the principle on which color-changing mugs and other such objects work. Since the term ‘thermochromism’ sounds a bit technical, the paint that they coat the mugs with is called ‘heat-sensitive paint’ – a paint that is sensitive to changes in temperature.
How to apply thermochromic paint?
Applying the thermochromic paint Hold the THERMO MARKER heat sensitive paint spray head down and shake vigorously to thoroughly mix the paint, continue even after you can clearly hear the ball bearings.
