Piezochromes: inks, pigments and piezochromic paints

Piezochromic pigments
Our expertise

To create piezochromic coatings and materials, that change color under
pressure (shock, impact, strain), OliKrom relies on 2 patented technologies:

Reversibles piezochromic pigments

Color change at a given pressure and color recovery when the constraint decreases.

Applications : visualization of the mechanical behavior of various materials under pressure (tensile, compressive and torsion loading), material health testing.

Irreversibles piezochromic pigments

Permanent color change above a given pressure.

Applications : non-destructive material testing during production, use or maintenance (folds, breaks, wear, corrosion, cracks) / Visual detection of impacts and shocks for the industrial and transport sectors.

    OliKrom custom-designs and produces piezochromic coatings and materials for the industry, that change color under pressure. Pressure-sensitive paints can serve for non-destructive material testing and impact detection. Non-destructive testing (NDT) by visual detection indicated by a color change can be used in various industrial sectors, including: petroleum industry (pipelines, tubes, bars, welds, tanks); shipbuilding industry (hull control); aeronautics (beams, aircraft wings, numerous engine parts, landing gear, etc.); aerospace and military; automotive industry (control of engine blocks); the steel industry; boiler making and piping manufacturing; the energy industry: nuclear reactors, boilers, piping, turbines, etc. (maintenance of facilities); Railways in manufacturing and maintenance, particularly for safety devices (axles, wheels, bogies); food inspection; civil engineering and building,…
