SFXC® Cholesteric Rainbow Liquid Crystal Screen Printing Ink is a ready-to-use, water-based thermochromic ink that produces a vibrant rainbow colour-changing effect in response to temperature.
This heat sensitive liquid crystal ink displays a full spectrum of colour transitions between approximately 25°C and 30°C (77°F to 86°F). As temperature increases, the coating shifts from red through green to deep blue, creating a visually striking and interactive finish.
When applied over a black background, the effect is at its most vivid, with the coating appearing almost invisible until activated.
Application & Performance
This liquid crystal ink is designed for screen printing onto paper, board, and fabrics. It can also be applied using stamping techniques where appropriate.
For best results, apply to a black backing to maximise colour visibility and contrast.
- Apply multiple coats to increase colour intensity and brilliance
- Produces up to 12+ colour transitions across the activation range
- Highly temperature sensitive with fast response
Note: While spraying can be used for a more even finish, this product is primarily formulated for screen printing applications.
Protection & Compatibility
Liquid crystal coatings are delicate and should be protected where required with a suitable water-based clear topcoat.
Do not use solvent-based products, as these will damage the liquid crystal layer.
Typical Applications
This liquid crystal ink is widely used in art, fashion, design, and educational projects, as well as temperature visualisation and interactive print applications.
Common uses include prints, packaging, thermometers, creative surfaces, and experimental design work.
Demonstration
Example Project
SFXC worked with design studio Bompas & Parr to create a colour-changing flower installation using liquid crystal technology.
