How Does Coppercoat Work?
The effectiveness of COPPERCOAT is driven by a continuous four-stage chemical process once the hull is immersed:
- Oxidation: Copper reacts with seawater, forming copper oxide.
- Transformation: Copper oxide converts into copper hydrochloride.
- Self-Cleaning: This unstable layer washes away through vessel movement, removing slime and early fouling.
- Reactivation: Fresh copper-rich epoxy is exposed, restarting the cycle.
Long-Term Durability & Electrolysis Protection
With an average applied thickness of 250 microns and a corrosion rate of less than 10 microns per year, COPPERCOAT delivers reliable protection for well over a decade.
The solvent-free epoxy resin provides additional benefits:
- GRP Hulls: Osmosis prevention
- Steel Hulls: Enhanced corrosion resistance
- Non-Conductive Formula: Prevents electrolysis and does not affect sacrificial anodes
