Solvatochromic, Chemochromic: pigments, paints and industrial coatings

Solvatochromic and chemochromic pigments
Our expertise

OliKrom produces industrial paints and coatings that change color in the presence of a solvent (solvatochromism) or a gas (chemochromism):


Reversible or irreversible color change in the presence of water and / or solvent. Modulation of the sensitivity threshold.

Modulation of the luminescence property in the presence of water and / or solvent.

Applications: detection of a water leak and / or solvent, anti-fraud, industrial marking, etc.


Change of color under the influence of a gas.

OliKrom adapts the trigger point of the color change and the nature of the gas.

Applications: gas detection on industrial site, control marking for the storage of hazardous materials, etc.

    OliKrom is a manufacturer of industrial solvatochromic and chemochromic pigments. We produce inks, paints, varnishes, resins that change color with a chemical substance (water, solvent, gas, …). Our solvatochromic coatings are sensitive to water and / or a solvent, reversibly or irreversibly depending on the specifications. Our chemochromic technologies change color depending on the nature of a gas and a programmed threshold. For example, we produce paints that are sensitive to moisture and that change color reversibly or irreversibly. The applications are numerous in the industrial field: for example for the detection of leakage of water and / or gas, for the control of transport and / or storage of certain hazardous materials.
