Geomet® 720
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. Geomet® 720 is the preferred zinc flake coating widely used by Asian OEMs.

- Application Process
Geomet® 720 can be applied by Dip-Spin, Spray, Dip-Drain-Spin using bulk or rack.; 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.; 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.
- High Corrosion Resistance
> 1000 hours without white rust; > 1500 hours without white rust; Results may vary depending on substrate, geometry of parts and type of application processes.
