B104B WHITE CONTRAST AID PAINT 500 ML PMUC – Magnetic Particle Inspection

B104B WHITE CONTRAST AID PAINT 500 ML PMUC is a specialist white background coating used in magnetic particle testing. Manufactured by BABBCO, the product is designed to improve the visual contrast between the inspected surface and the black magnetic particles applied during the testing process.

In visible magnetic particle inspection, the white background helps inspectors observe dark particle indications against the coated surface. This makes B104B white contrast paint an associated consumable for inspection processes using black magnetic detecting media.

The manufacturer describes B104B as a very fast-drying, high-opacity paint compatible with magnetic particle inspection techniques involving current flow, electromagnets and permanent magnets.

B104B is listed by RIO Middle East within its Magnetic Testing product category.

B104B White Contrast Paint Specifications

Values are based on published manufacturer information and should be checked against the current Technical Data Sheet.

How B104B Supports Magnetic Particle Inspection

Magnetic Particle Inspection is a non-destructive testing method used to examine ferromagnetic materials for relevant surface and near-surface discontinuities.

B104B serves as an MPI white background paint during inspection procedures using black magnetic detecting media.

The white coating provides a contrasting surface on which black magnetic particle indications can be observed.

The product itself is not a magnetic detecting medium. Its function is to provide the background coating used with the appropriate magnetic inspection material.

This distinction is important when selecting non-destructive testing consumables for a defined inspection procedure.

For example, B104B can be used alongside B103C Black Magnetic Ink 400ML Aerosol, which is separately listed by RIO Middle East.

Key Features of B104B White Contrast Aid Paint

High-Opacity White Background

B104B is formulated to provide an opaque white coating that contrasts with black magnetic particles during inspection.

The manufacturer’s product information identifies high covering power as a principal characteristic.

Fast-Drying Aerosol Format

The product is supplied as a 500 ml aerosol and is described as very fast drying.

The actual drying behaviour should be evaluated under the applicable inspection conditions rather than assumed to be identical in every environment.

Compatibility with MPI Techniques

BABBCO identifies B104B for use with magnetic particle inspection methods involving current flow, electromagnets and permanent magnets.

The magnetic testing procedure must remain appropriate for the material and inspection requirements.

Companion Magnetic Detecting Media

B104B is documented for use with black magnetic detecting media, including companion products identified in its technical literature.

These products perform a different function from the white contrast coating and should be selected according to the relevant inspection specification.

How to Apply B104B During MPI

The manufacturer provides application guidance for B104B aerosol.

The following is an overview of the documented process and does not replace a qualified inspection procedure.

Step 1 – Prepare the surface

Remove scale, existing paint residues, oxides or other contaminants where required.

The manufacturer identifies products including N120, B105 and SAFE 105 for relevant cleaning and degreasing operations.

Step 2 – Prepare the aerosol

Shake the B104B spray can thoroughly before applying the coating.

Step 3 – Apply the white background

According to the Technical Data Sheet, spray from approximately 20–30 cm and apply a thin, uniform white layer, preferably in a single pass.

Step 4 – Control the coating thickness

The published TDS identifies approximately 20–30 μm as a sufficient coating thickness.

Excessive thickness may create coating defects and reduce inspection sensitivity.

Step 5 – Conduct the magnetic particle inspection

Once the coating is ready according to the applicable instructions, continue with the specified magnetic particle inspection procedure and compatible black magnetic medium.

Step 6 – Remove the coating where required

Following inspection, the manufacturer identifies B105 or SAFE 105 as solvents for removing B104B.

Only trained personnel should carry out MPI using applicable inspection procedures, safety requirements and acceptance criteria.

B104B and Black Magnetic Ink: Understanding the Difference

The products serve distinct roles in a visible magnetic particle inspection process.

B104B should not be described as detecting defects independently.

Instead, its function is to improve the visual background for indications formed by black magnetic particles during the specified testing procedure.

Materials and Inspection Applications

B104B white contrast paint is documented for use with ferromagnetic metals.

Within the appropriate MPI process, the coating may be relevant to the inspection of ferromagnetic components where a white contrast background is specified.

Common application contexts for magnetic particle testing include the inspection of suitable ferromagnetic parts, welded areas and manufactured steel components.

However, suitability for a specific component or inspection method must be determined by the relevant inspection standard, material properties and approved procedure.

B104B should not be assumed suitable for non-ferromagnetic materials or used as a substitute for penetrant testing materials.
