Where it is used
Features
WCP provides a high-contrast white background that enhances the visibility of indications under visible light conditions, specifically where the background material has a similar colour to the particles. Black magnetic particles on grey steel are hard to read; black particles on a white coating are not.
The paint dries in approximately 20 seconds depending on ambient temperature, which allows quick processing time. On a production inspection where dozens of welds are being examined in sequence, drying time is the rate-limiting step.
When dry, WCP is resistant to the wet suspension fluids used in magnetic particle inspection, so the contrast background survives application of the suspension rather than washing away with it.
Formulated for low residual odour, which matters for a more operator-friendly environment when inspecting inside vessels, tanks and other confined spaces.
Easily removed with CalCheck R-2F Cleaner/Remover after inspection, so the component can be returned to service or passed to coating without an aggressive cleaning step.
Greater convenience and portability in aerosol form — no mixing, no decanting and no power supply required at the inspection location.

Operating essentials
Clean the test surface and allow it to dry. The longer WCP is stirred or agitated before use, the more uniform the spray will be. Apply a thin coat to the inspection area from approximately 150 mm from the surface.
Wait approximately 20 seconds for the paint to dry, depending on ambient temperature. The coating must be dry before magnetising, or the suspension will disturb it.
Magnetise the area to be inspected. Ensure continuous agitation of the suspension fluid; if using an aerosol suspension, shake vigorously before and during inspection. Apply the suspension to the test part and allow excess oil or water to run off the inspection area.
Inspect the surface under visible light. Collections of particles reveal discontinuities at the leakage fields. Clean and repeat the process with the magnetising direction changed — a defect lying parallel to the field will not produce a leakage field, so a single orientation is never a complete inspection.
These directions describe the basic process only. They may need to be amended by the user to comply with the applicable specification and inspection criteria provided by the contracting agency. Where this sheet and your approved written procedure differ, the written procedure governs.

Frequently asked
It provides a high-contrast white background for magnetic particle inspection, so that dark magnetic particles are clearly visible against the surface. It is used where the parent material is a similar colour to the particles, which on bare steel is almost always the case.
Magnetic particle testing (MT/MPI). It is not part of the CalCheck dye penetrant system — for penetrant inspection you need CalCheck VP-2S penetrant, R-2S cleaner/remover and D-2 developer. WCP complies with ASTM E709 and ISO 9934-2, which are magnetic particle standards.
Approximately 20 seconds, depending on ambient temperature. It must be fully dry before the part is magnetised and the suspension applied.
No. Once dry, WCP is resistant to wet suspension fluids. It is removed afterwards with CalCheck R-2F Cleaner/Remover.

4 °C to 50 °C (39 °F to 122 °F) in use. Cans must be protected from sunlight and never stored above 50 °C — worth noting for a UAE site store or a vehicle left in the sun.
