Thermochromic Liquid Crystal kit

The TLC-100™ is a Thermochromic Liquid Crystal kit designed for heat transfer studies and mapping temperature fields on electronic components or boards. The TLC-100™ features thermochromic liquid crystals (TLCs) which change color at a specified temperature starting at red, changing to green then blue. For electronics cooling applications, this provides the user accurate information about the location of hot spots on a device, their temperature and temperature gradient.

To map the temperature profile of a component or board, black ink is airbrushed on to the specimen. Then, TLCs with a particular temperature range (depending on the application), are sprayed onto the measurement surface. Once the device is turned on and the components are brought to activation temperature, the liquid crystals will begin turning red, then into different colors, representing the temperature distribution of the component or board.

Black ink and TLCs are non-destructive and wash off with the aid of soap and water.

Part Number Starting Temp (°C) Bandwidth Temperature Range
ATS-TLC-1-1 20 20 20-40°C
ATS-TLC-1-5 40 20 40-60°C
ATS-TLC-1-6a 50 10 50-60°C
ATS-TLC-1-8 60 10 60-70°C
ATS-TLC-1-10 70 10 70-80°C
ATS-TLC-1-12 80 10 80-90°C
ATS-TLC-1-13a 90 10 90-100°C
ATS-TLC-1-15a 100 20 100-120°C

Thermochromic liquid crystals are available in a variety of temperature ranges from 20°C to 120°C, each one with a particular bandwidth from 1°C to 20°C.

Kit Components

  • An airbrush for coating the component or board’s surface with black backing ink and liquid crystals
  • Air hose with couplings, valve for propellant cans and a 1/4" pipe adapter for use with to an air compressor
  • Two 30 ml bottles of Thermochromic Liquid Crystals (temperature ranges specified when ordering)
  • One 30 ml bottle of sprayable black backing ink for pre-treating the surface to be studied
  • Two glass jars, which attach to the airbrush, for dispensing ink and liquid crystals
  • Two portable and disposable, 255 g (11 oz.) cans of CFC-free air propellant
