Metal Cutting, Rust Release & Corrosion Protection

A drill bit running hot, a bolt locked by corrosion & exposed steel after fabrication are different workshop problems & each needs a product made for the job.

Soudal industrial sprays give Australian fabricators, mechanics, maintenance crews & workshop teams specialised solutions for metal cutting, seized components, electrical contacts & corrosion protection. The range includes Cutting Oil for reducing friction & heat during machining, Degrip All for penetrating rusted assemblies, Contact Spray for suitable electrical contacts plus Zinc Spray Matt & Alu-Zinc Spray Gloss for protecting prepared metal surfaces.

Product choice starts with the component rather than the aerosol can. Consider whether you need lubrication, penetration, contact cleaning or corrosion protection, then check the substrate, required finish & current product instructions before application. For fabrication-focused equipment & workshop setups, explore Metal Fab. Kits. For jobs involving aerosols, cutting or metal maintenance, browse Work Safety Protections for relevant workplace protection.

Identify what the metal or component needs first. The right Soudal industrial product becomes much easier to choose from there.

What Are Soudal Industrial Sprays?

Soudal industrial sprays are technical aerosols formulated for specific maintenance, machining & metal-protection tasks.

They aren't five versions of the same lubricant.

Cutting Oil reduces cutting resistance, friction & mechanical load while helping control heat during metalworking.

Degrip All uses high penetrating power to work into tight spaces around rusted or seized metal components.

Contact Spray is intended for cleaning & deoxidising suitable electrical contacts while helping manage moisture.

Zinc Spray Matt provides galvanising corrosion protection for zinc, iron & steel with a matt grey finish.

Alu-Zinc Spray Gloss combines galvanising protection with a shiny aluminium-silver finish.

That gives this collection a simple operating principle:

Identify the problem on the component first. Choose the aerosol second.

Why Choose Soudal Industrial Sprays?

Industrial maintenance rarely happens under perfect conditions.

A seized fastener may be buried inside machinery. A cutting tool can generate significant heat at the workpiece. Fabrication can remove existing protective coatings from steel. Electrical contacts can suffer oxidation or moisture ingress.

Purpose-matched aerosol products help tackle those problems directly.

► Cutting lubrication – reduces friction during drilling, milling, tapping, sawing & other metalworking operations
► Cooling performance – Cutting Oil helps manage heat where the tool meets the metal
► Penetrating action – Degrip All reaches narrow gaps around corroded fasteners & moving components
► Rust dissolution – assists with releasing seized metal parts
► Electrical contact maintenance – Contact Spray cleans & deoxidises suitable contact points
► Moisture management – helps reduce moisture interference around appropriate electrical components
► Galvanising protection – zinc-based sprays protect suitable iron & steel surfaces against corrosion
► Finish choice – select matt zinc or shiny Alu-Zinc according to the required appearance
► Access from different angles – selected Soudal aerosols can be applied through 360° orientation for awkward machinery access

Common Applications

Drilling, Tapping & Machining Steel

Metal tells you when the cutting conditions aren't right.

Heat builds. The tool starts working harder. The cut can become rougher.

Soudal Cutting Oil is a lubricant & cooling fluid developed for metalworking processes including:

► Drilling
► Milling
► Cutting
► Sawing
► Filing
► Tapping
► Turning
► Planing
► Punching

It is suitable for steel plus most ferrous & non-ferrous metals.

The formulation is non-corrosive, silicone-free & designed with anti-mist characteristics.

For associated workshop cutting work, Cutting Tools provides a natural next step.

Releasing Rusted Fasteners

Before increasing leverage, give the corrosion something designed to penetrate it.

Soudal Degrip All has very low surface tension, helping it reach small openings around seized or oxidised metal parts.

Applications include:

► Nuts
► Bolts
► Screws
► Flanges
► Machine components
► Axles
► Hinges
► Chains
► Moving assemblies
► Garden machinery

Remove loose contamination where practical, apply the penetrant & allow approximately 5–10 minutes for it to work before trying the component again.

For larger maintenance environments where seized hardware is part of everyday plant work, Quarry Crews Crusher Maintenance provides useful workshop & machinery context.

Electrical Contact Maintenance

Not every industrial aerosol is meant for a mechanical joint.

Soudal Contact Spray is intended for suitable electrical contact points including switches, stop contacts, batteries, measuring equipment & electrical installations.

It can help:

► Clean contact areas
► Remove oxidation
► Improve electrical contact
► Manage moisture
► Dehumidify suitable electrical wiring & tools

Electrical equipment should be switched off before application & only returned to service after the product has evaporated as required.

Protecting Steel After Welding or Fabrication

Fabrication can leave bare areas where the original protective layer has been removed.

Soudal Zinc Spray Matt contains a high-grade zinc compound with 98% zinc & provides galvanising protection for zinc plus unprocessed iron & steel.

Typical applications include:

► Weld joints
► Fabricated steel repairs
► Coachwork
► Gutter braces
► Prepared rust-affected areas
► Spot-welding applications

Its matt finish makes it useful where corrosion protection is required without a bright metallic appearance.

Creating a Shiny Galvanised Finish

Sometimes the protective coating remains visible.

Soudal Alu-Zinc Spray Gloss gives compatible iron, steel & zinc surfaces galvanising protection with an aluminium-silver finish.

Applications include:

► Visible weld repairs
► Fabricated frames
► Coachwork
► Gutter braces
► Steel maintenance
► Suitable spot-welding work

The finish provides a different visual result from Zinc Spray Matt while still addressing corrosion protection.

Product Selection Guide

Walk through the problem rather than comparing labels.

The Drill or Tap Is Running Hot

Choose Cutting Oil.

Its purpose is to reduce friction & mechanical load while cooling the work area.

Apply it to both the cutting tool & material before work begins then maintain appropriate lubrication throughout the operation.

A Bolt Won't Move

Reach for Degrip All before automatically reaching for more force.

Its low surface tension allows the penetrant to work into very small openings around the seized assembly.

Give the product time to penetrate.

An Electrical Contact Is Dirty or Oxidised

Choose Contact Spray for appropriate electrical contact maintenance.

Don't substitute a general mechanical penetrant simply because both products arrive in aerosol cans.

The task here is cleaning & deoxidising an electrical interface rather than releasing mechanical corrosion.

Bare Steel Needs a Matt Protective Coating

Use Zinc Spray Matt where its high-zinc, cathodic protection & matt appearance suit the repair.

Prepare the surface first by removing loose paint, loose rust & contamination.

The Protective Finish Needs to Stay Bright

Consider Alu-Zinc Spray Gloss.

It gives compatible zinc, iron & steel a shiny aluminium-silver protective finish.

Soudal specifies application in two layers with at least two hours between coats under the stated conditions.

Quick Workshop Comparison

Expert Tips

Keep Cutting Oil at the Cutting Edge

A quick spray at the start may not be enough during a longer machining operation.

Keep both tool & material appropriately lubricated throughout the work so the oil continues reducing friction & heat where the cutting actually occurs.

Give Degrip All Time to Work

Penetrating oil works by getting into the space you can't easily reach.

Apply the product then allow approximately 5–10 minutes before trying the seized fastener. Repeat where required rather than immediately escalating the force applied.

Surface Preparation Still Matters Under Zinc

A galvanising aerosol doesn't turn loose corrosion into a sound substrate.

Remove loose rust, old loose coating, grease & contamination before applying Zinc Spray Matt or Alu-Zinc Spray.

Choose the Finish Before the Repair Is Visible

Matt zinc & shiny Alu-Zinc aren't simply alternative product names.

If the repaired area will remain visible, decide whether the surrounding work calls for a matt grey finish or an aluminium-silver appearance before spraying.

Build Alu-Zinc Protection in Layers

Soudal specifies two coats of Alu-Zinc Spray with at least two hours between applications.

Shake the aerosol thoroughly before each coat & follow the current application instructions for spray distance, drying & topcoating.

Electricity Changes the Rules

Contact Spray has a specialised electrical role but application still requires the equipment to be switched off.

Don't restore power until the spray has evaporated according to the product instructions.

Match PPE to the Actual Aerosol Job

Metal cutting, corrosion treatment & aerosol coating can create different exposure conditions.

Choose protective equipment according to the product SDS & task. Hand & Arm Protection supports jobs where skin & hand protection are required while Respiratory Protection & Accessories provides options where respiratory controls are appropriate.

Maintenance Includes the Equipment Around the Repair

A cleaner fastener or protected weld doesn't help much if the tools doing the work are neglected.
