Thermochromic ink is blue below 15C and translucent above 15C. Translucent at room temperature and blue when put in the fridge or below 15C.
Thermochromic Ink is a magical coating that changes colour when exposed to certain temperatures. It uses ‘chill and reveal’: at room temperature the ink is translucent and shows any surface beneath, and when it cools below its activation temperature, it turns blue. The effect can be done again and again.
Our thermochromic ink comes in 2 parts (slurry and binder), which must be mixed 50/50 prior to use. You cannot use the slurry without the binder: it will simply dry and fall off. The binder is what fixes the slurry to the surface. Tell us your application and we’ll advise on printing it.
Our products can be screen printed onto textiles, paper and board. Please let us know if this product is being applied to different substrates such as wood, plastic, metal, glass or ceramics. It is best to apply this ink using thin coats. Apply via screen printing or a foam roller; avoid brushes, which can’t apply the ink thinly or evenly enough.
If using heat to dry the print, keep it low and short: stay below 180C, as briefly as possible, and avoid prolonged heat above 75C. Brief heat at 100C for 12 minutes is fine.
This thermochromic ink is very popular for cold applications such as colour changing drink labels or place mats. Use to hide messages or text that appear when chilled.
Storage: Keep it in a cool, dark place, ideally at 20C or below, with the lid tightly closed, and use within 12 months. Don’t let it freeze, and don’t store it with food or drink. Direct sunlight and UV damage the thermochromic materials.
Before use, please read the Technical Data Sheet (TDS) and the Safety Data Sheets for the thermochromic slurry (SDS) and the binder (SDS). For step-by-step advice on paper, board and fabric, read our guide: How to screen print thermochromic ink
