Sherwin DUBL-CHEK BO-1 Magnetic Particle Black Oxide – 400ml | Visible Magnetic Particle Inspection | Pack of 3 | Business Delivery Only

Professional Black Oxide Magnetic Particle Aerosol for Non-Destructive Testing and Weld Inspection

Supply Solutions Group supplies the Sherwin DUBL-CHEK BO-1 Magnetic Particle Black Oxide – 400ml in a convenient pack of 3 aerosols to NDT technicians, welding inspectors, fabrication workshops, engineering companies, mining operations, maintenance contractors and industrial organisations throughout Australia.

DUBL-CHEK BO-1 is a professional visible magnetic particle inspection product designed for non-destructive testing (NDT) of ferromagnetic materials. It consists of finely divided black magnetic oxide particles suspended in a highly refined light petroleum oil. When applied during magnetic particle inspection, the particles respond to magnetic leakage fields created by discontinuities in the test material, rapidly accumulating to produce clearly defined black indications.

The black particle colour provides strong visual contrast, particularly when BO-1 is used with DUBL-CHEK CP-2 White Contrast Paint. This makes the system particularly effective for detecting surface and slightly subsurface discontinuities in welds, castings, forgings, machined components and other ferromagnetic parts.

BO-1 incorporates a 360° aerosol valve, allowing the can to spray from different orientations for easier inspection of awkward or difficult-to-access components. The aerosol format provides convenient, controlled application and can be used with both portable and stationary magnetic particle inspection equipment.

Supplied as a pack of 3 × 400ml aerosols, this product is classified for Business Delivery Only due to aerosol dangerous goods transport requirements. Supply Solutions Group currently lists this three-pack configuration for business customers.

As an Indigenous-owned industrial supplier and procurement partner, Supply Solutions Group provides professional NDT, welding and inspection consumables backed by responsive customer service, procurement support and Australia-wide delivery.

How DUBL-CHEK BO-1 Works

During magnetic particle inspection, the ferromagnetic component being tested is magnetised. Discontinuities in the material can create magnetic leakage fields. When BO-1 is applied to the inspection surface, its magnetic particles are attracted to these leakage fields and accumulate around the discontinuity, producing a visible black indication for inspection.

For improved visual contrast, DUBL-CHEK CP-2 White Contrast Paint can first be applied as a background. The component is then magnetised and BO-1 applied while maintaining appropriate agitation of the particle suspension. The surface is subsequently inspected under suitable visible lighting. Inspection procedures should always follow the applicable NDT specification, procedure and acceptance criteria.

Why Choose Sherwin DUBL-CHEK BO-1?

Sherwin DUBL-CHEK BO-1 provides a convenient and reliable solution for professional visible magnetic particle inspection. Its fine black magnetic particles respond rapidly to leakage fields and form clearly defined indications, while the aerosol format makes application straightforward in both workshop and field environments.

The 360° spray valve is particularly useful when inspecting complex assemblies, welds and components where conventional upright aerosol application would be difficult.

Companion Products

For a complete visible magnetic particle inspection system, BO-1 can be used alongside:

• DUBL-CHEK CP-2 White Contrast Paint – creates a contrasting white background to improve visibility of black particle indications.
• DUBL-CHEK DR-64 Cleaner/Remover – assists with surface preparation and removal of inspection materials where appropriate.

Frequently Asked Questions

What is Sherwin DUBL-CHEK BO-1 used for?
BO-1 is used for visible magnetic particle inspection of ferromagnetic materials. Its black magnetic particles accumulate at magnetic leakage fields associated with discontinuities, making defects easier for qualified inspectors to identify.

What colour are the magnetic particles?
The particles are black, providing strong visual indications during inspection.

Can BO-1 be used with white contrast paint?
Yes. DUBL-CHEK CP-2 White Contrast Paint is a companion product that can provide a white background to improve the visibility of BO-1's black indications.

Can the aerosol spray upside down?
The aerosol incorporates a 360° valve, allowing application from different orientations and making it particularly useful when inspecting difficult-to-access components.

What equipment can BO-1 be used with?
It can be used with both portable and stationary magnetic test equipment.

How many aerosols are included?
This Supply Solutions Group configuration contains 3 × 400ml aerosols.

Why is this product Business Delivery Only?
Because this is an aerosol product subject to dangerous goods transport requirements, Supply Solutions Group restricts shipping to business deliveries.
