DINITROL METALLIC underbody protection spray 500 ml

Description

DINITROL Metallic Spray is a bronze protective spray for underbodies and other metal parts exposed to corrosion, mechanical stress and elevated temperatures.

Once dry, it forms a firm, flexible, waxy protective film that resists stone chips, road salt and wear. Its high heat resistance means it can also be used in areas exposed to elevated operating or process temperatures.

1500 hours in the salt spray test At the recommended dry film thickness of 300–500 μm.

Stone-chip resistance Suitable for exposed areas of the vehicle underside subject to mechanical impact.

Safe on paintwork According to the technical data sheet, it has no effect on paint — there is no need to mask surrounding parts.

Bronze shade instead of black Suitable where the protection should visually blend in with the original brown coating rather than leave a black patch.

Typical use in workshops and anti-corrosion treatment

• local underbody repairs
• renewal of existing anti-corrosion protection
• painted metal surfaces
• PVC and similar protective coatings
• spare parts, machinery and steel structures
• protection of parts during long-term storage or transport

The material does not attack zinc, rubber or plastic parts and is also suitable for environments with high corrosive load.

Repairs and renewal of existing protection

DINITROL Metallic Spray is also suitable for local repairs and renewal of existing underbody coatings. It can also be used to repair a protective coating made with DINITROL 4942.

The original coating must be firm, clean, dry and compatible. Loose, cracked or poorly adhering areas must be removed before application.

Surface preparation and application

The surface must be clean, dry and free of corrosion before application. Remove dirt, grease and loose residues of old protective coatings.

Key Features

• Clean and dry the surface thoroughly
• Shake the can thoroughly before use
• Apply evenly to the prepared surface
• The recommended wet film thickness for the spray is approximately 1100 μm — the spray has a lower solids content than the liquid packs, so more of it has to be applied
• The recommended material and application temperature is 15–30 °C

Penetrating coat on corroded substrates

If corrosion is already present on the surface, clean it mechanically first and then apply a penetrating coat such as DINITROL ML or DINITROL 3650. Only then is the final protective coat applied.

Spray or larger pack?

The aerosol is practical for local repairs and smaller jobs. For complete underbody treatment or larger jobs, a larger pack of DINITROL Metallic and professional application equipment are the better choice.

Suitable guns and application equipment can be found in the DINITROL Application Equipment category.

Final protective coat DINITROL Metallic is not intended to be painted over or covered with another protective coat.

How to protect the underbody against corrosion properly

Successful anti-corrosion treatment depends on the condition of the substrate, its preparation, suitable pre-treatment and the correct thickness of the final protective coat.

Frequently asked questions – Why bronze and not black?

The bronze-brown shade comes close to the look of brown wax coatings, so the repaired area does not stand out as a contrasting patch. If you want a black top coat, choose DINITROL 4941 / CAR.

Is DINITROL Metallic Spray suitable for repairing DINITROL 4942?

Yes. Metallic Spray can be used for local repairs and renewal of a DINITROL 4942 protective coating. The original coating must be firm, clean and dry, and poorly adhering areas must be removed.

Can overspray be removed?

Yes, with white spirit, which the technical data sheet lists as the recommended solvent.

How long does an unopened can keep?

Two years when stored at 15–30 °C. Do not expose the aerosol to temperatures above 50 °C or to direct sunlight.
