Crack Luminescence [NEW TEST METHOD]

RILUMINATI - Innovative method for early detection of fatigue cracks

General description:

Two-component special layer based on an acrylic resin, consisting of pigmented components:

  • RILUMINATI 815 indicator layer, fluorescent
  • RILUMINATI 816 overlay, black

The advantages:

Less effort for the user due to:

  • unique coating
  • extensive testing
  • uncomplicated application (visual inspection)

Functional principle:

  • RILUMINATI 815 emits light as fluorescence under UV light. This allows us to detect the resulting crack.
  • RILUMINATI 816 covers the indicator layer and at the same time prevents the indicator layer from reflecting to achieve the highest possible contrast between the crack and the indicator layer.
  • Both layers of the system tear open when the metal cracks and the crack edges of the indicator layer are exposed.
  • When the spot is irradiated with UV light (wavelength 365 nm), the crack shows a fluorescent glow of yellow-green colour.
