Surtec 650V Process:

Surtec 650V is a modern, chromium-free conversion coating process used primarily on aluminium and aluminium alloys. Surtec 650V provides high-quality corrosion protection and enhances the surface’s ability to bond with paints, adhesives, and other coatings. It is particularly well-regarded in industries where environmental impact is a concern, as it does not use harmful hexavalent chromium compounds.

Surtec 650V Process steps:

  • Pre-treatment Cleaning: The first step is thorough cleaning to remove any contaminants, including oils, dirt, and grease. This is usually done with a degreasing solution or solvent cleaning method to ensure the surface is pristine.

  • Rinsing: The aluminium is then rinsed to remove any remaining cleaning agents.

  • Surtec 650V Application: The parts are then immersed in the Surtec 650V solution, which typically contains inorganic compounds, such as zirconium and titanium-based compounds. This treatment forms a protective layer that binds to the metal, providing both corrosion resistance and improved adhesion for coatings.

  • Coating Formation: The Surtec 650V process creates a thin, transparent conversion coating that adheres tightly to the surface of the aluminium, forming a protective barrier against corrosion. This layer can be slightly tinted, but it remains generally transparent.

  • Rinsing and Drying: Once the coating is applied, the parts are thoroughly rinsed to remove any excess solution, then dried.

Key benefits of Surtec 650V 

  • Chromium-Free: Surtec 650V is a completely chromium-free alternative to traditional chromate conversion coatings, making it an eco-friendly choice that complies with modern environmental standards, such as RoHS (Restriction of Hazardous Substances).

  • High Corrosion Resistance: It provides excellent corrosion resistance, making it ideal for use in harsh environments, including marine and industrial applications.

  • Superior Adhesion: The coating creates a highly effective bonding surface for paints, powder coatings, and adhesives, ensuring long-lasting finishes.

  • Excellent Durability: Surtec 650V enhances the longevity of aluminium parts by providing a protective layer that resists scratching and wear.

  • Non-Toxic and Environmentally Safe: The process uses zirconium and titanium- based compounds, which are safer and less harmful to both the environment and the workers compared to traditional chromate-based treatments.

Applications of Surtec 650V

  • Automotive: Surtec 650V is commonly used on automotive components, where excellent corrosion protection and adhesion for subsequent coatings are crucial, particularly in parts exposed to road salts and chemicals.

  • Aerospace: It is used in the aerospace industry for aluminium parts that require a non-chromium-based protective coating for environmental compliance without compromising performance.

  • Marine: Surtec 650V is ideal for parts that are exposed to harsh, saltwater environments, providing long-lasting protection against corrosion.

  • Architectural: Aluminium components in the construction industry, such as frames and trims, are treated with Surtec 650V to ensure both aesthetic appeal and long- term durability.
