Zinc Flake (Organometallic)

LAURENTCOAT® 565

Solvent-based

Description

LAURENTCOAT® 565 is a high-performance organometallic coating developed to provide superior corrosion protection for iron and steel parts. Its system combines an inorganic zinc flake basecoat, which provides sacrificial protection, with an organic topcoat with high aluminum content that acts as a physical barrier against corrosive agents.

Thanks to its chromium-free formulation and non-electrolytic application process, LAURENTCOAT® 565 prevents hydrogen entrapment and is especially safe for hardened steels. It also includes integrated friction control, making additional sealers unnecessary and delivering a uniform, consistent, high-performance finish.

This coating is suitable for screws, nuts, springs, and stamped parts, and can be applied by Dip-Spin, Dip-Drain, or Spray. Its resistance can reach up to 1,000 hours in salt spray testing under ASTM B117, making it a reliable solution for industries that require maximum durability, protection, and technical stability.

Key Features

Superior Resistance

Up to 1,000 hours of salt spray resistance per ASTM B117.

Controlled Friction

No need for additional sealers thanks to the built-in friction agent

Compatibility

Suitable for screws, nuts, springs, and stamped parts.

Versatile Application

Dip-Spin, Dip-Drain, or Spray. Can also be applied over electrolytic zinc plating bases.

Solvent-based, chromium-free

Thermally cured at 280°C, safe for hardened steels.

No Hydrogen Entrapment

Non-electrolytic, acid-free application with thermal curing that preserves the steel’s strength.

Uniform Coating

Uniform thickness from 5 to 12 microns, ensuring a consistent, high-performance finish.

High Corrosion Resistance

  • Cathodic Protection: Zinc acts as a sacrificial anode, protecting iron or steel against corrosion.
  • Passivation: Metal oxides and chromium stabilize the coating and reduce corrosion between metals.
  • Barrier Effect: The zinc and aluminum layer acts as a shield against corrosive agents.
  • Self-Healing: Surface damage seals itself as the zinc reacts with air, naturally repairing the layer.
