Spray zinc coating (dark) UN 400 ml — corrosion protection, aerosol, MTP 91085

UN Spray zinc coating (dark) in a 400 ml aerosol provides a zinc-rich protective layer designed to prevent and slow down corrosion on ferrous metal surfaces. The product forms a uniform, adherent coating that can be applied directly to bare or prepared steel and iron. It is formulated for touch-ups, weld seam protection and general metal restoration where a zinc sacrificial layer and a dark finish are required. The aerosol format ensures easy application to hard-to-reach areas and small surfaces.

Advantages

The dark zinc spray delivers corrosion protection through a zinc-rich film that acts sacrificially to protect steel and iron. It offers fast drying and good adhesion to prepared metal surfaces, with an even spray pattern that reduces runs and sags. The aerosol container enables controlled, localized application without brushes or mixing. The dark finish helps mask repairs and provides a consistent appearance on treated areas.

Suitable for

• Touch-up corrosion protection on automotive bodywork and chassis components
• Protecting weld seams and joints after welding
• Restoration of metal parts, brackets and fittings
• Industrial maintenance and repair of steel structures

Key specifications

• Form: aerosol spray, 400 ml can
• Coating type: zinc-rich metallic coating
• Finish: dark metallic appearance
• Drying: fast surface dry suitable for handling within short timeframes
• Adhesion: formulated for good bonding to prepared steel and iron
• Application: spray application for small areas and spot repairs

How to use

Before application, clean the surface of oil, grease, loose rust and dirt using an appropriate degreaser or mechanical preparation. Shake the aerosol can thoroughly for the time specified by the manufacturer to ensure even dispersion of pigments and binders. Hold the can upright at the recommended distance (typically 20–30 cm) and apply several thin, even coats rather than a single heavy coat, allowing short flash-off times between passes. For weld seams and heavily corroded areas, remove loose scale and apply a primer or additional coats as needed to achieve the required coverage and protection. Allow the coating to dry fully according to ambient conditions before subjecting the part to service.

Usage recommendations

Use in well-ventilated areas and avoid inhalation of spray mist. Protect surrounding surfaces from overspray and follow health, safety and disposal instructions from the product label. Store the aerosol upright in a cool, dry place away from heat sources and open flame, and keep out of reach of children.
