Product Announcements: Temperature Indicating Coatings and Materials

Thermochromic liquid crystals (TLC's) react to changes in temperature by changing color. TLC's have Chiral (twisted) molecular structures and are optically active. Direct white light is selectively reflected by the expansion and contraction of the helix with change in temperature. (read more)

Three thermochromic / photochromic ink test kits are now available that will allow you to immediately create stunning thermal or UV activated visual effects. Each kit contains three different colors and a user's guide that will have the user producing interactive graphics in a matter of minutes. These water based screen ink kits are easy to apply and clean up with a brush or stamp. (read more)

Thermochromic inks, pigment, and coatings provide a cold, touch, or high temperature color change for packaging and labels; available in a temperature range of -10° C to 69° C. Permanent color change temperature labels, 29° C to
290° C.

Thermax® non-reversible color changing labels are oil, water, and steam resistant, offering inexpensive evidence of temperature achiev... (read more)

Thermochromic Liquid Crystals (LCs) can be highly temperature sensitive, change to many colors, and are more expensive than leuco dyes. LC's start black below their temperature range; go through the colors of a rainbow, and then black again above the temperature range. LC's are reversible in that they can be used over and over again. The picture shows an example of a liquid crystal sheet... (read more)

Activation temperature points range from low refrigeration type temperatures through normal body temperatures to high temperatures that exceed the pain threshold.

• Cold Activated Thermochromic Ink is used on labels and packaging to create a color change when cooled. (Clear to Color: 15ºC / 59ºF)
• Touch Activated Thermochromic Ink will vanish when...
