LAURENTCOAT® 787 is our premium water-based coating, formulated with zinc and aluminum flakes to provide maximum corrosion resistance without the use of hexavalent chromium.
Its cold application through Dip Spin or Spray processes ensures a high-quality, uniform metallic silver-gray finish, with a low film thickness of 5 to 12 microns that does not affect part dimensions.
Thanks to its advanced technology, it reaches from 720 up to more than 1000 hours in ASTM B117 salt spray tests.
CHARACTERISTICS
- Superior Corrosion Resistance: Provides up to 1000 hours without red rust according to ASTM B117 testing.
- Uniform Coating: Consistent 5–12 micron thickness, ensuring high-performance finishing.
- No Hydrogen Embrittlement: Non-electrolytic application, acid-free and thermally cured to maintain steel strength.
- 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.
