Ressi Rustof CC
Ressichem introduces Ressi Rustof CC, a specialized rust converter and corrosion control solution developed to protect ferrous metal surfaces from further oxidation. This advanced treatment chemically transforms rust into a stable protective layer, improving coating adhesion and extending substrate life. Ideal for industrial maintenance, structural steel, pipelines, and fabrication projects, it minimizes surface deterioration while preparing metals for topcoat applications. Ressi Rustof CC is easy to apply, fast reacting, and highly effective in humid or corrosive conditions, making it a dependable solution for long-lasting anti-corrosion performance.
Ressi RustOff – CC
Rust Inhibitor / Rust Converter Coating
Ressi RustOff – CC is a single-component acidic formulation designed to chemically convert
existing rust (hydrated ferric oxide) on steel surfaces into a stable, inert, black ferric complex compound.
It penetrates rust layers and forms a dense, adherent conversion film, temporarily stabilizing the corroded
surface and providing a sound base for subsequent coating applications.
Note: Ressi RustOff – CC is intended for maintenance or non-critical applications only.
It is not a substitute for proper mechanical or abrasive blast surface preparation.
FEATURES & BENEFITS
- Converts existing rust into a stable, paintable surface
- Single-pack, ready-to-use formula (no mixing required)
- Fast-acting chemical conversion of ferric oxide
- Improves short-term corrosion resistance before overcoating
- Easy application by brush, roller, or spray
RECOMMENDED USES
- Maintenance of light to moderately rusted steel surfaces where blasting is impractical
- Industrial, fabrication, agricultural, and general maintenance applications
- Use as a pre-treatment before applying a compatible primer or coating system
- Not recommended for: structural steel, immersed or continuously wet environments
SURFACE PREPARATION
- Remove all loose rust, mill scale, oil, grease, and dirt by wire brushing, scraping, or power tool cleaning
- Surface must be dry and free from loosely adhering material
- Best results are achieved on firmly adhering rust, not on bare or heavily corroded steel
- Avoid application over oily or greasy substrates
APPLICATION
- Apply by brush, roller, or spray
- Use as supplied – thinning is not recommended
- At 25°C, coating becomes touch dry within 60–90 minutes
- Clean tools immediately after use with a suitable thinner
- After rust conversion, apply a compatible primer over the surface
COMPATIBILITY
- Compatible with alkyd, epoxy, and polyurethane primers after full cure
- Do not apply zinc-rich primers directly over unwashed converter residues
- If required, wipe surface lightly with a clean damp cloth to remove unreacted acid before overcoating
