Corrosion Block Liquid 4-Liter Refill - Non-Hazmat, Non-Flammable Non-Toxic

Corrosion Block is your ultimate solution for protecting marine and boating equipment from the relentless effects of saltwater and high-moisture environments. This advanced, non-toxic, and non-flammable fluid forms a durable barrier, ensuring your vessels and electronic components remain in optimal condition for longer periods.

Why Choose Corrosion Block?

Corrosion Block utilizes sophisticated polar bonding chemistry to deliver exceptional protection for both metal surfaces and electronic systems. Unlike conventional wax-based products, Corrosion Block penetrates deeply into joints, connectors, and fasteners, replacing corrosive saltwater with a moisture-resistant hydrophobic film that effectively halts corrosion.

Key Features

• Instant Corrosion Defense: Eliminates corrosion on contact, whether your equipment is submerged or exposed to high ambient moisture.
• Advanced Protection Chemistry: Synthetic additives penetrate once-corroded cells, replacing saltwater that then evaporates, leaving behind a lasting protective film.
• Hydrophobic Barrier: Creates a clear, moisture-proof layer that prevents new corrosion from forming.
• Safe and Environmentally Friendly: Non-toxic and non-flammable formula, including the propellant used in aerosol versions.
• Trusted Worldwide: Widely used in critical applications such as marine vessels, power generating stations, fuel depots, gas and petroleum refineries, and more.
