Description

Chiral Nematic Liquid Crystal Coating

Product Code: LC-INKS-25C5W

Transform ordinary surfaces into dynamic, colour-changing displays with this remarkable thermochromic liquid crystal coating. At room temperature, it appears colourless, but as heat is applied, it bursts into a vibrant spectrum of colours, transitioning from red to green, and finally to blue within a 25°C to 30°C range.

What is Liquid Crystal?

Liquid crystals are a fascinating state of matter, exhibiting properties of both liquids and solids. Our chiral nematic liquid crystal coating is incredibly sensitive to temperature changes. Even tiny shifts cause the liquid crystals to re-arrange their molecular structure, altering how they reflect light and resulting in a captivating display of colour shifts.

Unleash Your Creativity:

This versatile coating is frequently used in LCD displays, but its potential extends far beyond. Imagine the possibilities in:

  • Education & Research: Bring science to life with interactive demonstrations of heat transfer and the fascinating world of liquid crystals. Visualise temperature changes in real-time for experiments.

  • Art & Design: Create stunning, dynamic artwork that responds to temperature. Integrate interactive elements into installations, sculptures, and fashion. Add a unique dimension to murals and interior design.

  • Printing & Packaging: Develop eye-catching packaging and promotional materials with temperature-activated colour changes. Create interactive labels that reveal hidden designs with heat.

  • Temperature Indication & Safety: Develop innovative temperature indicators for industrial processes and machinery. Create visually engaging safety labels that alert users to potential hazards.

Application and Care:

For the most vibrant colour shifts, apply this liquid crystal coating to a black or dark-coloured surface. Use an airbrush at approximately 20 psi to apply multiple thin coats. A water-based topcoat, like our Sprayable Lacquer, is essential to protect the liquid crystals and ensure longevity.
