Zinc Phosphate Plating

Zinc phosphate coating is a chemical conversion coating process applied to metal surfaces to improve corrosion resistance and create an ideal surface for subsequent painting applications. During the process, a microcrystalline phosphate layer is formed on the metal surface, significantly enhancing the adhesion of paint and other coatings.

Widely used in the automotive, home appliance, and metal manufacturing industries, zinc phosphate coating not only provides a protective layer but also serves as an essential pre-treatment that improves the performance and service life of paint systems. By precisely controlling process parameters, Çinkosan achieves a uniform phosphate crystal structure on every component, ensuring high-quality surface preparation for subsequent coating operations.

• Provides excellent adhesion for both conventional and electrostatic powder coating applications, improving paint performance by up to 90% through its textured surface structure.
• Increases paint impact resistance and flexibility, helping protect painted surfaces against scratching after curing.
• Improves the corrosion resistance of metal surfaces and delays the formation of rust beneath the paint layer.
• Enhances the adhesion of lubricants to the surface.
• Produces a uniform crystal structure, resulting in high-quality light grey or dark grey surface finishes.
• An ideal pre-treatment before powder coating and cathodic electrocoating (e-coating).
• Cost-effective solution suitable for high-volume production.

• Automotive components
• Home appliance components
• Structural steel components
• Metal furniture manufacturing
• Machinery parts
• Industrial equipment
• Pre-treatment for electrostatic powder coating

Çinkosan continuously monitors the chemical balance of its phosphate baths to ensure consistent process performance. Regular laboratory testing enables continuous monitoring of crystal structure, coating quality, and overall process performance, ensuring solutions that meet international quality standards.
