Corrosion is a major problem that can dramatically add to a project’s life cycle costs, especially for bridges, water towers and other metal structures.
A LUMIFLON-based coating:
- Resists degradation due to weathering and exposure to ambient chemicals
- Over the course of many years, loses little of its thickness
- Keeps corrosion initiators from getting past the topcoat and degrading the zinc-rich primer underneath
- Has an estimated coating life of 60 years or more
