GEOMET® 720 is a completely chrome-free, water based coating passivated with zinc and aluminum flakes in a binder. This high performance, low-film, functional zinc flake coating is designed to protect fasteners, stampings, and a variety of metallic hardware. This zinc flake coating was developed to meet the requirements of Asian OEMs.

Entirely free of toxic metals like Chromium, Nickel, Cadmium, Lead, Barium and Mercury. Water based coatings mean water clean up that is worker friendly with no offensive odor.

24 g/m²	1000 hours without red rust
24 g/m² + topcoat	1500 hours without red rust

APPLICATION

The process of applying GEOMET® requires the substrate to be clean bare steel -- free of oil, heat-treat scale, rust and other contaminants.

• Dip Spin is widely used bulk processing system for small parts.
• Spray for specialized parts or large parts typically one half pound or larger.
• Dip Drain spin for large parts such as tubes.

Parts are subjected to a five minute minimum pre-cure at 200°F to set the coating, followed by a higher temperature at 625°F for a complete cure.
