Description
Thermochromic ink is Magenta below 31°C and translucent above 31°C.
Thermochromic Ink is a magical coating that changes colour when exposed to certain temperatures.
The effect used for this activation temperature is 'rub and reveal', so a hand or heat source of 31C and above can be used to make the coated surface transparent. When the ink cools and is below its activation temperature, it will return to Magenta. This change repeats itself again and again.
Our thermochromic ink comes in 2 parts (slurry and binder) must be mixed 50/50 prior to use. Please let us know when you have placed an order so we can include the correct 2 part system. You cannot use the Slurry without the binder and it will simply dry and fall off, the binder is what fixes the slurry to the substrate.
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.
