Temperature indicating coatings and materials include chemical indicators, labels, pigments, paints or other indicators that change color when exposed to a certain temperature. These products are either irreversible and designed for one-time use providing evidence of attained temperature or are reversible and can change back and forth to provide an indication of the current temperature. Photochromic pigments, paints and inks change color when exposed to UV light reversing to colorless when removed from the UV light exposure.

Operating Principle

Temperature indicating labels, coating, paint, ink and pigments incorporate materials that exhibit thermochromism, a physical property that undergoes a change in color in response to a change in temperature. Photochromic paints exhibit a photochemical reaction to UV light changing from an essentially colorless state to colored.

Microencapsulating Thermochromic Liquid Crystals and Leuco Dyes increases accuracy, stability and life expectancy of the product. Leuco Dyes, Thermochromic Liquid Crystals and Chemical Indicators are thermochromic substances LCR Hallcrest offers as a label, coating, pigment and paint. Photochromic Paint is also available as a Powder, Slurry, Ink and Masterbatch.


Coating – Coatings are a layer of something deposited upon a material surface to add or enhance desired properties.

Pigment – a dry insoluble color matter or substance usually pulverized which when suspended in a liquid vehicle becomes a paint, ink, etc.

Paint – is a pigmented liquid mixture used on a substrate as a decorative or protective coating. Color changing paint can be used to monitor surface temperature and alert operators to potential hazards, maintenance requirements, etc.

Ink – A colored liquid or powder that is printed, sprayed, rolled to substrates to create markings, patterns or graphics. Color changing inks are smart and react to environmental fluctuations with color change.

Labels – an adhesive backed thin film for adhering to a surface with color changing material that can be either a reversible or a permanent change indicator with a scale or alert color.
