Piezochromic paints for construction

Piezochromic paints are paints that change colour after putting a defined load or pressure to them.

They come in two versions: a version with a reversible effect returns to its original colour when the pressure releases, and in the irreverisble version – after exceeding a defined value of pressure, the paint irreversibly changes its colour.

This type of paints is used e.g. for observing influence of loads/pressure on an object in order to detect excessive pressure, visualise mechanical behaviour of different materials under pressure (tension, compression, torsion), examine condition of materials.

Irreversible paints are used for detection of destruction of materials during production, usage or maintanance (folding, fracture, wear, corrosion, cracks) as well as for visual detection of impact and shocks in industries and transport.
