Description

What is Chemetall Supramor 4 Black?

• Chemetall Supramor 4 Black is a ready-to-use color contrast magnetic ink ideal for the inspection of ferromagnetic materials, structures and components by the magnetic particle inspection
  method. A typical application is the inspection of welds, pressure vessels and pipeline in the oil, gas and petrochemical industries as well as power plants.
• Supramor® 4 Black consist of finely divided black magnetic particles suspended in high flash point, dearomatized, odorless petroleum distillate designed to provide good particle mobility. The particles have been selected for their high magnetic response, low coercivity and prolonged operational life.
• Supramor® 4 Black and MPI Diluent HF use a hydrocarbon corresponding to the AMS 2641, Type 1 Magnetic Particle Inspection Vehicle with a flash point exceeding 93°C / 200°F.
• Supramor® 4 Black is available as bulk material and as aerosol. It offers optimal performances when used with the WCP 712 or 722 contrast paint and the remover S80.

Method of use

Surface temperature should be between -20 and 75°C (-4 to 165°F). Components are magnetized and Supramor® 4 Black is applied to the test area, normally by spraying immediately prior to and during magnetization. Application of Chemetall Supramor 4 Black should cease before the magnetization is switched off. Defects will show up as well defined black indications and inspection should take place in good white light of at least 500 Lux (refer to the controlling specification for levels of ambient light acceptable for inspection).

White contrast paint
It is not practical to use Chemetall Supramor 4 Black on dark substrates as it would be difficult for the inspector to identify indications against the dark background. For this reason, the white contrast paint WCP 712 (or 722, peelable) is frequently used to provide a contrasting background against the black indications, (alternatively, fluorescent fluids such as the Lumor® inks may be used if a UV light is available). WCP712 can then be left on the surface or removed with the remover S80 (WCP 722 can also be peeled off).

Effects on materials
When Supramor® 4 Black is used in the prescribed manner, no significant corrosion will occur
on ferrous materials. Equipment/tanks should be constructed of stainless steel. (source)
