Impa 1412 KELA RUST Rust Converter, organic chelating agent (1l)

IMPA 1412 KELA RUST Rust Converter / Rust Inhibitor – 1 L

IMPA KELA RUST 1412 is a milky liquid rust conversion treatment designed for situations where corrosion cannot be fully removed by sanding or blasting. It reacts with the rust layer and turns it into a strongly bonded protective film that helps slow down or stop further corrosion on steel surfaces.

During conversion, rusted areas shift to a blue-black appearance. Once cured, the converted layer acts as a barrier against moisture and oxygen and can be overcoated, making it a practical base for subsequent paint or anti-corrosion systems.

The 1 litre pack is ideal for larger jobs such as body panels, underbody sections and industrial steel parts, providing a cost-effective solution while maintaining consistent conversion performance across wider surfaces.

Key features

• Chemically converts rust in areas where mechanical removal is limited
• Deep penetration into corroded zones for improved effectiveness
• Leaves a dense polymer film after drying
• Paintable once the reaction is complete
• Ready to use; if needed, dilute with water only
• No solvents – do not add or clean with solvent-based products
• Lead-, zinc- and chromium-free

Specifications

Application guidelines

• Degrease first: remove oil/grease; knock off loose rust and scale so the product can contact the stable layer.
• Rinse if contaminated: if exposed to salts/chemicals, rinse with water before applying.
• Apply: brush, roller, spray bottle or spray gun.
• Film build: match application to rust thickness and avoid runs.
• Cure: allow the reaction to complete before overcoating (typically at least 3 hours).
• Visual check: rusted areas should turn blue-black when conversion has occurred.
• Overcoat window: suitable for most paint systems within 6–7 days after treatment.

Spray parameters

Warnings & storage

• Do not apply in direct sun or on hot metal—rapid drying can reduce conversion quality.
• No solvents: do not add solvents and do not use solvent cleaners.
• Avoid metal containers/tools; do not pour leftovers back into the original container (it may harden).
• Frost sensitive: store at +5 to +10°C.
