A water-based sprayable ink ideal for creating for the perfect finish when used with any standard spray equipment or airbrush.

SFXC Liquid Crystal Ink changes through a rainbow spectrum of colours when touched with warm hands or another heat source.

This is a delicate water based product that can only be used in conjunction with other water based products.  You cannot use this product with any solvent based products as this will kill the gentle liquid crystal properties of this living protein.

At room temperature, this liquid crystal coating appears to be colourless. However, as the temperature rises the coating will change from red, to green and finally blue. Our liquid crystal has a bandwidth of 24°C to 29°C. This means that the ink starts to change at 24°C and completes its change at 29°C.

Liquid Crystal looks best on a black background, but does work well on other colours such as blue and red. Avoid applying LC to light coloured surfaces.

Ink coverage = 35ml per square meter per coat.

We recommend applying several very thin coats, building up to 2 or 3 coats for instance. The amounts of coats will depend on the surface material you are working with.

The coating thickness will alter the texture of the coat. Thin coats are matte and slightly rough. Thicker coats create a smooth, gloss finish.

Spray 15-20cm above your surface. Air brush pressure = 20 psi/1.41kgcm-²/1.3 bar (approx.)

Use a water based topcoat to protect the sensitive crystals in this material. Otherwise, it can scratch off. A water-based clear coat or lacquer should be used. Do not use with solvent based products. It will damage the Liquid Crystal. We recommend using our Sprayable Lacquer.

This ink is mainly used in LCD displays but can also be used for education, printing, design, and arts and crafts. Liquid crystal ink has been used in hundreds of innovative applications including, jewellery, footwear, CD covers, packaging, business cards, thermometers, hot warning labels, thermochromic sheets, thermal mapping, interior design, automotive coverings.

Since Liquid Crystal is one of the most expensive (but fascinating) smart materials available, we stock a cheaper option: adhesive Liquid Crystal Sheets. These have been coated with four layers of liquid crystal and can be cut and applied to most substrates.

For screen printing, you can purchase our Liquid Crystal Ink.
