Thermochromics and Photochromics
We supply a range of high-quality reversible thermochromics (from colourless at a high temperature to a solid colour at a specified lower temperature) and irreversible thermochromics (from a neutral body colour at low temperature to a solid colour at a set higher temperature). Photochromics change from a light colour indoors to a darker colour outdoors. This is a reversible process.
The reversible thermochromics change from a colour to colourless on heating at a specified temperature. When cooled the original colour is restored. They are available in a range of activation temperatures and colours. Activation temperatures range between 0oC to + 65oC. We offer powders, slurries and finished inks suitable for most print processes. The main applications are for brand security, brand identity and novelty.
The irreversible thermochromics change from colourless to a colour on heating at a specified temperature. It is a single irreversible colour change. They are available in a range of activation temperatures and limited colours. Activation temperatures range between 55oC and 200oC. We offer concentrates and finished inks suitable for screen and flexographic printing. The main applications are brand security and safety.
We supply a range of photochromics in various colours. These are colourless when not exposed to UV radiation and become coloured under UV light. The colour change is reversible. We offer powders, slurries and finished inks suitable for most print processes. The main application is novelty.
