LAURENTCOAT® 565 is a solvent-based, chromium-free coating that combines:
- Inorganic zinc-flake basecoat: sacrificial protection for iron and steel.
- Organic topcoat with high aluminum content: physical barrier against corrosion and integrated friction control.
CHARACTERISTICS
- Superior Corrosion Resistance: Up to 1000 hours of protection in ASTM B117 salt spray testing.
- Controlled Friction: No need for additional sealers thanks to the integrated friction modifier.
- Compatibility: Suitable for bolts, nuts, springs, and stamped parts.
- Versatile Application: Dip-Spin, Dip-Drain, or Spray. Can also be applied over electrolytic zinc coatings.
- Solvent-Based & Chromium-Free: Thermally cured at 280 °C, safe for high-strength steels.
- No Hydrogen Embrittlement: Non-electrolytic process, acid-free, and thermally cured to maintain steel strength.
- Uniform Coating: Consistent thickness of 5 to 12 microns for a high-performance finish.
- Advanced Corrosion Protection System:
- Cathodic Protection: Zinc acts as a sacrificial anode, protecting steel against corrosion.
- Passivation: Metal oxides and chromium stabilize the coating and reduce galvanic corrosion.
- Barrier Effect: The zinc-aluminum film creates a physical shield against corrosive agents.
- Self-Healing: Minor surface damages are naturally sealed as zinc reacts with air to regenerate the coating.
