Description

Effective Rust Conversion

Würth Rust Converter offers a highly effective solution for stopping ongoing corrosion and stabilising rusted metal surfaces. The dispersion-based formula penetrates deep into the rust layer, where it reacts with iron oxide to form a stable, insoluble, blue-black, metal-organic complex. This process neutralises active corrosion, preventing further rust formation and extending the service life of metal components.

Environmentally Friendly Formula

Unlike aggressive acid-based rust treatments, this product uses an environmentally friendly dispersion system. It delivers the same high-performance results while being safer to use, making it suitable for both professional and industrial environments where sustainability is a priority.

Paintable and Versatile

After only 3 hours of reaction time, the treated surface can be painted over with water-based or solvent-based coatings. This allows for flexible integration into existing finishing processes. It also serves as a suitable substrate for fillers, enabling further restoration or refinishing work as required.

Industrial -Grade Applications

Engineered for reliability, Würth Rust Converter is widely applicable across industries such as vehicle and caravan construction, shipbuilding, steel fabrication, pipeline and tank construction, agriculture, forestry, and municipal maintenance. Its robust temperature resistance of up to 120°C ensures performance under demanding operational conditions.

More Information

Application Instructions

  1. Ensure the surface is clean, dry, and free from grease.
  2. Remove loose rust, paint, and dirt with a wire brush, scraper, or similar tool.
  3. Stir well before use.
  4. Apply a thin, even coat with a brush or roller, ensuring no runs or excess build-up.
  5. Allow a minimum of 3 hours reaction time before overcoating.
  6. Paint over with water- or solvent-based protective coatings within 3-48 hours of application.
  7. Mask off any surfaces not intended for treatment to avoid accidental contact.

Usage Notes

  • Do not wash treated surfaces with water.
  • Avoid application in direct sunlight, on hot surfaces above 40°C, or when there is a risk of frost.
  • Protect the product form frost at all times.
  • If the product comes into contact with painted surfaces, wash off immediately.
  • Clean application tools with water immediately after use.
