30 Degree Red To Yellow Security Ink Temperature Sensitive Ink

Thermochromic inks are temperature sensitive compounds that change color or disappear with variations in climate. These changes can be temporary or permanent depending on the application. This technology is often employed in instances where products need to be stored in controlled environments

1. Display a specific color at room temperature. After heating, the color will disappear and become colorless. After cooling, it will return to the original color immediately. It's a reversible, colorless to color, temperature sensitive ink

2. it is colorless at room temperature, and becomes another color after heating. After cooling, it will return to the original colorless color. Because of its reversible change process, it is called reversible colorless to colored temperature change ink.

3. The ink displays one color at room temperature and changes to another color after heating. Because the change process is reversible, it is called "reversible temperature change to color ink";
