Primer Rittal 2440.905 black ready-mixed 0.15 L for coloring and corrosion protection

Rittal 2440.905 black ready-mixed 0.15 L is a pre-mixed primer formulated for surface priming and corrosion protection of metal and industrial enclosures. Supplied in a small volume for touch-ups and minor repairs, this air-drying primer provides a black base layer that improves adhesion of subsequent topcoats and helps reduce the risk of rust on exposed metal edges and repaired areas.

Advantages

This ready-mixed primer is ready to use without thinning, which simplifies spot repairs and on-site maintenance. Its black finish provides consistent coloration under dark topcoats and helps conceal repaired areas. The formulation is intended for good adhesion to metal substrates and powder-coated or wet-painted surfaces, and it air-dries to a durable base suitable for overcoating.

Suitable for

• Touch-ups of powder-coated or wet-painted metal surfaces
• Minor repairs to industrial enclosures, cabinets and panels
• Priming exposed edges and bare metal prior to topcoating
• On-site maintenance where small-volume ready-mixed primer is needed

When it may not be suitable

This product is formulated for small repair jobs and touch-ups rather than large-scale coating of entire surfaces. It is an air-drying primer intended as a base for topcoats and may not provide the final protective properties required for long-term outdoor exposure unless properly overcoated with a suitable topcoat.

Key specifications

• Color: black (RAL 9005-compatible appearance)
• Volume: 0.15 L ready-mixed container
• Application: brush or spray suitable for touch-up work
• Drying: air-drying formulation
• Recommended substrates: metal, powder-coated and wet-painted surfaces (for repair and priming)

How to use

Prepare the surface by cleaning off loose rust, dirt, oil and salts, and abrade glossy areas lightly to promote adhesion. Shake or stir the product well before use. Apply a thin, even layer to the prepared area using an appropriate applicator (brush or spray) for touch-ups. Allow the primer to air-dry according to ambient conditions before applying a compatible topcoat. For best results, ensure the primer is fully dry and follow the topcoat manufacturer's recommendations for overcoating.

What to consider before purchase

• Intended use: designed primarily for small repairs and touch-ups, not full-surface coating
• Substrate compatibility: best for metal and previously coated surfaces; test on unfamiliar materials first
• Topcoat requirement: this is a primer—select a compatible topcoat for final protection and appearance

Usage recommendations

Use in well-ventilated areas and follow safety and disposal instructions on the product label. For larger areas or permanent outdoor exposure, plan a full coating system with appropriate primers and topcoats to ensure long-term corrosion protection.
