General Description:
WCP-2 is a ready to use, rapid drying white contrast paint used to provide a white background to enhance visible magnetic particle indications.
WCP-2 is specially formulated to produce a thin dry film giving a high opacity semi-matt finish. It is low in sulphur and halogens and contains no chlorinated hydrocarbons.

Composition: 
WCP-2 is composed of acetone and inorganic pigments. The aerosol propellant is carbon dioxide.

Application: 
Parts should be cleaned and dried prior to testing to ensure a more uniform test surface. Shake WCP-2 to ensure uniform distribution of particles. Apply a uniform thin film of WCP-2 to the test surface. Wait one minute to allow the WCP-2 film to dry. Apply magnetic particles to the test surface. Observe indications formed around leakage fields. If base material has a high retentivity, indications will remain visible. If base material has a low retentivity, the indications will appear to slowly fade away.

Post Inspection Cleaning: 
The parts must be properly demagnetized before cleaning to ensure ease of particle removal. Acetone will remove WCP-2.
