Neoastra DGCW
Fluorescent Magnetic Ink - Day Glow Concentrate
Suspended Magnetic Particles
Neoastra DGCW 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 DGCW is ideal for the inspection of welds, pressure vessels, structures, pipes, castings, forgings and most other ferromagnetic components.
Neoastra DGCW should be viewed using a UV light with a surface intensity exceeding 1000μW/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 DGCW is a water based concentrate and should therefore be diluted before use. Typically one 500mL bottle of concentrate will make 25L of product. Neoastra DGCW it is not classified as hazardous after dilution.
Certified to meet Sulphur and Halogen levels required by military, nuclear and ASME standards.
Available in 500mL bottles.
