WCP712 and WCP722 White Contrast Paints
Product information
Chemetall WCP712 and WCP722 are quick drying white paints which are designed specifically for the use in the colour contrast method of magnetic particle inspection.
WCP712 and WCP722 provide a dense white background against which black or red indications of defects can be seen readily. WCP712 and WCP722 are ideal for use with either oil based or water based magnetic inks. WCP 722 is a peelable version of WCP 712. WCP712 and WCP722 are available as aerosol cans.

Instructions for use
WCP712 and WCP722 can be applied to the area to be inspected by spraying (or brushing for WCP 712). Application by aerosol is by far the most common method as it is much easier to obtain a dense even film. Aerosols are also convenient to use, particularly for in-situ inspection. There can be more wastage of product with brush application due to the volatility of WCP 712.
It is essential that aerosols are shaken before use and, for brushing applications; containers must also be shaken thoroughly. Surface temperature should be between 0 and 50°C (30-120°F).
WCP 712 or 722 is applied to dark coloured ferromagnetic surfaces and allowed to dry before applying the magnetic particles. This ensures a good colour contrast between the white paint and the red or black particles making it much easier for the inspector to identify and interpret the indications.
Removal
Remove WCP712 with Cleaner S76 for best results.
WCP722 can be peeled off
All components, parts, or inspection areas must be properly demagnetised before cleaning to ensure easy particle removal. Cleaned parts may be treated with a temporary film protective coating if longer corrosion protection is required.
Storage
Store in a well-ventilated area away from magnetising equipment and heat sources. Product age, exposure to elevated temperatures, and / or exposure to a strong magnetic field may adversely affect particle distribution. Please refer to safety data sheet for additional instructions.
