H.W. Sands’ pigments contain microencapsulated Cholesteric Liquid Crystal mixtures that react visibly to changes in temperature. We provide the Reversible Thermochromic Liquid Crystals (TLC) in a water-based ink formulation for application to clear polyester and PVC substrates.  

H.W. Sands’ most popular and ideal for human contact is our TLC ink, MSA5000. The MSA5000 is a water based screen ink which begins its color change at 25C (activation temperature) with a 5 degree bandwidth. See below image and normal specification for MSA5000.
