Description

Aqua thermochromic pigment that turns colorless at 77 Fahrenheit or by the human touch. Color changing pigments can be used for print, plastic or paint.
This heat sensitive aqua pigment has a very deep blue/green color in in temperatures below 25°C / 77°F. It is not reactive to UV light, but still has a variety of uses. It's fine, fluffy consistency will mix smoothly into a variety of mediums and can very easily stick to hands and other surfaces without the use of adhesive. When the powder comes in direct contact with temperatures above 25°C / 77°F it will turn white, or what some would call colorless. If you mix this pigment into a clear medium in a low enough ratio and apply it thin enough, its white or colorless state can actually appear transparent! A few cool uses we've found with it are: Mix it with a clear paint, then draw an ocean scene with whales, sharks, or other sea creatures and paint over it. When you place your hand over the paint it will become clear and reveal the sea creatures underneath! Use it to paint over a red base paint on an object that needs a heat indicator. When the temperature is warm enough the blue will disappear indicating the surface is now hot!
