Product Data Sheet – MAGNAVIS WCP-2

White Contrast Paint

Chemical product icon - contrast paint

General Description

MAGNAVIS® WCP-2 is a ready-to-use, rapid-drying white contrast paint. It produces an opaque white background to enhance visible magnetic particle indications on dark-coloured test surfaces.

WCP-2 is suitable for use in both dry method and wet method magnetic particle inspection.

Composition

WCP-2 is composed of inert inorganic pigments and an acrylic binder in a solvent blend based on acetone.

It is low in sulphur and halogens, and contains no chlorinated hydrocarbons.

Benefits

  • Produces a bright white, opaque coating with minimal glare/reflections, which allows you to see indications more easily.
  • Dries quickly and evenly without bubbles or flakes, creating an optimal surface for faster inspection.
  • Can be used with wet or dry method magnetic particles on virtually any part.
  • Conforms to ISO 9934 specifications.

General Method of Use

Clean the component before testing to provide a suitable test surface.

Shake the can to ensure that the paint particles are evenly distributed.

Apply an thin, even film of the paint to the test surface by spraying, dipping or brushing. Allow to dry.

Apply magnetic particles to the test surface and observe any indications formed around leaks/defects. If the test material has a high retentivity, indications will remain visible; othwerise, the indications will slowly fade.

After inspection, demagnetise the test part before cleaning. If required, the dried paint film can be removed using a wire brush or a common solvent, such as acetone.
