Chromatic color6/27/2023 What's more, they require specialized equipment for proper integration into various products, and that equipment (as well as the TLCs themselves) often adds significant expense to a manufacturer's production costs. Their performance can suffer with repeated exposure to UV light, water and chemicals. Their color consistency means they can indicate heat levels to within a few degrees. Temperature accuracy is a strong suit for TLCs. Hang the thermometer in a bedroom and you'll see a rapid change in color that indicates an accurate temperature. Then, these capsules are blended with other materials and used in products, such as room thermometers. This encapsulation process offers some protection for the TLCs and maintains their thermochromic properties. The liquid crystals must first be microencapsulated into billions of tiny capsules that are just a few microns in size. You can't just plop TLCs onto a product to make it change colors. This happens because as temperature rises, spacing between the crystals changes, and as a result, they reflect light differently. In this low temperature state, TLCs may not reflect much light at all, thus, appearing black.Īpply warmth and increase it bit by bit, though, and you'll see the TLCs shift from black to just about every color of the rainbow. At lower temperatures, these liquid crystals are mostly in a solid, crystalline form. Their properties change depending on environmental conditions TLCs exhibit different colors in response to temperature changes. Be ready - your eyes in are in for a surprise. Keep reading and you'll see how these crazy inks pull their chameleon tricks. Paired with a clever bit of creativity, such products provide real visual wow. Doing so can help them grab consumers' attention and differentiate a brand from those that use old-fashioned inks with just one static hue. There are numerous companies integrating these dynamic, eye-catching inks into their products. They're still used in all sorts of silly novelty items, but they have many useful and creative applications, too: thermometers, clothing, paint, drink containers, toys, battery indicators, plastic products of all kinds and much more. Since mood rings, thermochromic inks have evolved at a steady pace. And some beer cans sport graphics that appear when their hoppy contents are cool enough to provide optimum refreshment. More recently, a microwaveable maple syrup bottle featured a thermochromic label that indicated when its buttery, delicious goodness was warm enough for your waffles. Thermochromic inks first hit the mainstream in the 1970s, appearing in one of that era's lasting icons - the mood ring, which supposedly used the wearer's body heat as a sign of his or her emotional state.
