PAK Detector is a spray paint that makes identifying the presence of tar in road surfaces easy
by detecting the PAH (polycyclic aromatic hydrocarbons) compounds.
Road and highway maintenance requires work to be carried out to the various road surface layers. Certain asphalts containing tar and those laid back in the ‘80s and ’90s contain compounds that are today prohibited as they can cause health problems for those who handle or are in contact with them.
It is therefore important to know whether these are present when maintenance has to be carried out, in order to isolate them from other waste. This identi cation can be carried out by detecting the PAH strongly present in the tar.
PAK Detector is a white marking paint that contains a speci c solvent to dissolve the PAH, causing a color change to yellow. The PAK Spray can allow you to identify the presence of PAH in tar at levels of 100 ppm and above.
It does not provide an of cial measurement but merely an indication of the presence of tar in the asphalt.
Drying time: approximately 15
Temperature range: -10°C to 50°C.
Pigments: mineral and organic. Solvents: speci c to dissolve the PAH.
Propellant: specific blend of isobutane and propane.
Recommendations for use
Use head down.
BEFORE use: shake thoroughly. AFTER use: purge head up. Spray a thin layer onto the surface to be treated. Leave
to dry. If PAH are present, the
white surface will become yellow/brown. In the event of doubt, using a UV lamp will reveal the presence of PAH through a yellow-green colouration.
