Aerosol Contrast White 712 (CHMAGWH)

WCP712 White Contrast Paint is a quick drying white paint which is designed specifically for use in the colour contrast method of magnetic particle inspection. WCP712 provides a dense white background against which black or red indications of defects can be seen readily. WCP712 is ideal for use with either oil based, or water based magnetic inks.


WCP712 can be applied to the area to be inspected by spraying or brushing. Application by aerosols 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 insitu inspection. WCP712 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 itmuch easier for the inspector to identify and interpret indications.

It is essential that aerosols are shaken before use and, for brushing application, containers must also be shaken thoroughly.

Application by brush is less practical s it is more difficult to obtain an even film and there can be more wastage of product due to the volatility of WCP712. WCP712 is used extensively in conjunction with Supramor 4 Black ink in aerosols particularly for the in-situ inspection of welded fabrications or structures, pressure vessels and pipelines.
