Thermochromic pigments, inks & paints

Thermochromic Pigments
Our expertise

To create smart temperature-sensitive inks, paints and coatings, OliKrom relies on 3 patented thermochromic technologies:

Reversible color change (OliKrom@TSoft)

Color change at a defined temperature T1 and color recovery when temperature drops back below T1.

The temperature inducing color change, T1, can range from -100°C to +100°C.

Applications: real-time hot-bearing monitoring, industrial temperature control, thermal mapping, packaging and interior decoration, …

Peinture et encre thermochromique réversible à mémoire

Reversible color change with memory effect (OliKrom@TMemory)

Color change at temperature T1 and color recovery when temperature drops below T2. The gap between entre T1 et T2 characterizes the memory effect.

Applications: industrial maintenance control, identification of breaks in the cold chain, control of the thermal history of specific elements, verification of appropriate storage conditions, identification electrical components under overload or short circuit conditions, or overheating engine parts.

pigments thermochromique irreversible

Irreversible color change (OliKrom@TOne)

Permanent color change over a given temperature. The temperature inducing color change can range from +60°C to +900°C.

Applications: Visualization of any temperature increase over a given threshold (thermal mapping, prevention of thermal faults, …).
