Irreversible Thermochromic
Irreversible Thermochromic Thermochromic Pigment

This thermochromic pigment is black below 60°C and becomes translucent when the temperature exceeds 60°C. Once the thermochromic pigment has changed colour it will not change back.

Irreversible pigment can be used in certain plastics and coatings to help show if a product or a surface has reached high temperatures. It is mainly used for the manufacturing processes to indicate that the correct temperatures have been reached when curing materials with heat. It is also used for safety applications such as indicators on diesel engines. You could mix this product with a water based screen printing binder and apply it to labels that change colour if the temperature of 60°C has been reached. Irreversible thermochromic products are also used for the transportation of food to ensure the produce has not exceeded certain temperatures.  This product can be added to SFXC screen printing binder and the SFXC sprayable lacquer. 10% should be added to 90% of your chosen binder. Please make small tests to see if the thermochromic pigment works well with your chosen binder. 

The particle size of this pigment is around 20um. 

SFXC® Thermochromic pigment is microencapsulated and can be mixed with solvent and water based mediums. 

Please view the TDS and MSDS before use. Please fully test SFXC products before print runs, production, installations or end products. Sample sizes are available in the drop down menus.

We can create custom coatings and powders so please contact us if this is not what you are looking for. However, this product is a good place to start for testing as a custom order has an MOQ of 1kg and the price can be higher compared to our standard range of thermochromic materials.

We hope you enjoy using our products as much as we do.

We do offer reversible thermochromic pigments if this is not what you are looking for.
