Thermochromic Leuco Dye
LCR Hallcrest manufactures a range of Thermochromic products using Leuco Dye technologies. These are supplied in a variety of forms, both Reversible and Irreversible under the brand name Chameleon®.
We mix numerous Leuco Dyes with colour developers and a series of fatty acids, esters and alcohols that each have defined melt points to provide
a range of materials that respond to different temperatures producing a variety of colours.
These systems can take the form of either microencapsulated slurries or concentrates before they are finished into their final form of a Label, Ink or Plastic component.
These products all change colour over a temperature range specific to their formulation providing a simple cost effective method of monitoring
