Tried and tested fluorescent dyes for UV fluorescence excitation for the detection of leakages

The established UV tracer for pipe burst detection

Now offering an even broader selection of colours for advanced possibilities

Trotec Luminat is an aqueous dispersion that can be diluted in water but does not metabolise and that practically does not leave any recognisable traces in the visible wavelength range.

Only with UV irradiation in the optimum wave range, the formaldehyde-free fluorescent pigments of this tracer are excited to maximum fluorescence and become visible with intensive brilliance.

To ensure that users can dispose of this optimum UV fluorescent dye with its ideal brilliance for any task, Trotec Luminat is now offering a selection of four luminous colours. In addition to the well-established Luminat Green, this products is also available as Luminat Red, Luminat Blue and Luminat Purple.

Luminat is especially suited for tightness tests at water-bearing layers of flat roofs or the inspection of drains and downpipes. The fluorescent material can be detected and made visible under UV light at its discharge points.

Furthermore, Trotec Luminat can be used for non-destructive materials testing (NDT) as well as for leakage detection if the capillary flow only plays a marginal role and the UV tracer is not to leave any visible traces.

Important: Luminat must not be used as food colourant!

A few practical benefits:

tried and tested UV tracer for detecting pipe bursts
No metabolisation – ideal for long-term examinations
Very intensive colour brilliance when excited by UV light
Colour-neutral application – does not leave any visible discolourations on most surfaces
Fluorescent dye made in Germany, 100 % formaldehyde-free
Available in different colours – for any environmental condition and preference

Typical Luminat applications are for instance examinations of flat roofs for detecting a sealing flaw by means of dye testing.

Since Luminat appears colourless in normal light, discolourations on masonry, ceilings and walls are practically invisible to the naked eye.

* Chemical tracers (marking agents) are potentially toxic – depending on the treatment duration and exposure – hence applications with drinking water or groundwater discharges could be problematic. Based on the situation the natural colours of the Trotec Pure series can provide a deployment alternative that is 100 % organic. Otherwise Uranin Green represents the means of choice, especially for verifying the flow path or leak testing in brickwork. If the tracer must for instance not leave any colour traces on the item and at the same time needs to be chemically stable in the long run, we recommend using the UV fluorescent dyes of the Luminat series or Uranin Blue, which are only visible when irradiated with UV light. Compared to Luminat, Uranin Blue is furthermore characterised by an excellent capillary flow.
