Product Data Sheet – BYCOTEST 104A, 104plus
White Contrast Paints
BYCOTEST® 104A and 104plus are ready-to-use, rapid-drying white contrast paints used to provide a white background to enhance visible magnetic particle indications. They produce a thin dry film, giving a high-opacity, semi-matt finish.
Both paints give a particularly good contrast to our black magnetic ink, BYCOTEST 103, ensuring that even the smallest indication can be seen.
These paints are composed of inert inorganic pigments and an acrylic binder in a solvent blend; 104A is based on ethanol and 104plus is based on acetone.
Both are low in sulphur and halogens, and contain no chlorinated hydrocarbons.

Like all Magnaflux materials, our contrast paints are closely controlled to ensure batch-to-batch consistency, optimum process control and inspection reliability.
General Method of Use
Clean the component before testing with our C10 cleaner, 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, the components should be properly demagnetised before cleaning. If required, the dried paint film can be removed using a wire brush or with our C10 cleaner.
