Fluorescent Magnetic Ink - Day Glow
Suspended Magnetic Particles
Neoastra DG is a fluorescent magnetic ink for use in MPI and was formulated to give defined indications using the highest grade of magnetic particles which were selected for their response to very low magnetic fields and for low coercivity.Neoastra DG is ideal for the inspection of welds, pressure vessels, structures, pipes, castings, forgings and most other ferromagnetic components.
Neoastra DG should be viewed using a UV light with a surface intensity exceeding 1000 μW/cm2 with the benefit of allowing moderate ambient light. Anecdotally it has been demonstrated that defects can be found with up to 500 Lux of ambient light present. However to comply with BS EN 9934-2:2015 levels must be restricted to 20 Lux.
Neoastra DG aerosols use a CO2 propellant which gives an excellent active product to propellant ratio when compared to liquid propellants like Butane, Isobutane and Propane.
Available in 400mL aerosols and in 5L bulk containers.
