Industrial safety

Guarantee the safety and reliability of the industrial tool

OliKrom is the specialist in smart color change coatings for industrial safety. Our intelligent coatings are capable of changing color and/or luminescence on demand. They offer multiple possibilities to increase safety and detect hazards.

We make color talk to track the presence of an anomaly on an equipment, a product or a system, for the protection of workers.

Programmed smart materials

OliKrom works with many companies to develop innovative solutions to enhance safety: protection of tools, equipment and workers, detection and control of hazards, reporting of anomalies or incidents.

We use the richness offered by smart materials for this purpose. The options for creating interactive devices (sensors, indicators, components, etc.) with their environment are limitless.

Custom coatings deposited on equipment can become reactive to temperature, light (photochromes and luminescents), pressure, solvents or gases in order to monitor industrial risks: leaks, heating, etc.

This allows us to contribute to the resolution of many industrial problems, as in the case of our partnerships in aeronautics with the Safran Turbomeca and Airbus groups.

Tracking, alerting and detecting anomalies

A very interesting property of smart materials is their ability to modify their optical response autonomously, without any power supply. This allows us to intervene for the protection of workers and equipment in very restrictive environments, where any electrical source is totally or partially forbidden during certain phases of intervention.

No electricity needed, the color change in a smart material occurs only when the threshold is crossed. It is a thermodynamic process that acts as a passive solution. It's all in the initial programming of the material to calibrate the right trigger threshold and the reversible or irreversible nature of the color change.

Color change materials are becoming alternative solutions to electronic sensors for equipment hazard monitoring. For example, the use of thermochromic coatings can replace thermocouples and/or thermometers: this is now a reality.

Visual detection


For some industrial uses, the alert function sought is a visual detection. The process of color change is often preferred for its simplicity of interpretation and its understanding by everyone.

For example, an operator who observes the color change of a thermochromic ink or paint on the surface :

  • of a motor to warn of an overheating condition or of an electrical element to identify a short circuit,
  • a tank to visualize its filling level,
  • an industrial pipe (or valves, ovens...) to control the occurrence of an anomaly.

In this case, we adjust the color change to the malfunction to follow. It is necessary to integrate the notions of duration of the event (time scale, number of ON/OFF cycles), choice of colors, implementation...

Monitored detection

Monitored detection

For some industrial risks, our teams develop solutions to create an interaction with an optical device (camera, video surveillance, drone, robots...).

Depending on the application, we adjust the wavelength, the selectivity and the reactivity of the materials. This allows us to automate the detection, for example, an intelligent coating allowing a drone to detect the presence of a leak on an overhead pipe.

This wavelength selective work allows us to adapt the detection to the demand. We can accentuate the desired component according to the RGB color space. Other requests lead us to interact in the infrared or ultraviolet range.

Amplified detection: making the invisible visible

For certain equipment safety and worker protection issues, the objective is to detect the first signs of a malfunction.

In this context, we are developing a series of technical coatings, paints and inks, incorporating fluorescent and/or phosphorescent components with optimized properties.

Some solutions are currently deployed for quality control of certain products during production and/or after return to the after-sales service (to visualize the conformity of a coating on an object). Other applications aim to detect the early signs of corrosion, the presence of residual water.

An example of a partnership with the Safran Turbomeca group

Our teams have worked alongside the Safran Turbomeca Group to develop thermochromic coatings for mapping the temperatures of components integrated into complex environments, such as engines in operation subjected to intense mechanical stress.

This development was supported by the FRIMATT program (Formulation of Innovative Coatings for Adapted Temperature Measurement on Turbomachinery) as part of the 16th call for projects from the French government's Fonds unique interministériel (FUI) dedicated to funding projects from competitiveness clusters.
