Rub and Reveal plastic Thermochromic film.
When the sheet reaches 31°C, it becomes translucent, revealing your hidden layer. This can be achieved with warm hands or by rubbing with a finger or thumb to create friction.
If this covering is applied to a cold surface it will struggle to change.
Safe, easy to use with a wipeable surface. Our Thermochromic film can be cut to size with scissors or a guillotine.
