How does cold galvanizing RUST-ANODE®
et RUST-ANODE PRIMER®
Cold galvanizing with RUST-ANODE® and RUST-ANODE PRIMER® Technology electrochemically protects treated surfaces by actively bonding with the base metal and creating an electrolytic link.
☛ RUST-ANODE® ’s cathodic reaction has an electrochemical link with the metal and continues to protect the steel, even if a 4-mm scratch is made in the RUST-ANODE® coating.
Applied to rust that is dust-free, RUST-ANODE® technology will convert the rust to iron hydroxide and will form an electrical connection through the coating, resulting in the desired cathodic protection.
Ⓘ RUST-ANODE® et RUST-ANODE PRIMER® form a zinc metal coating on steel surfaces.
RUST-ANODE® and RUST-ANODE PRIMER® technology provides an excellent bond and doesn’t crack even when metal expands from heat or is damaged. It can also be painted.
The cold galvanizing that challenges rust and turns back the clock
On old zinc or metal coatings where the zinc layer is worn and no longer providing protection, RUST-ANODE®and RUST-ANODE PRIMER® are the only technologies capable of binding (combining) properly with the previous hot dip galvanizing or metal coating and restoring the material’s cathodic protection.
RUST-ANODE® and RUST-ANODE PRIMER® technology make it possible to give your hot dip galvanizing a new life, without dismantling your existing structures.
These products can be used in a workshop or directly on-site without taking your structures apart. Application is by brush, roller or spray-gun.
☛ RUST-ANODE® transforms (inhibits) the appearance of rust and prevents it from forming. Rust is prevented from spreading and RUST-ANODE® bonds permanently.
- Can be applied to a new substrate or a rusted substrate as well as to existing hot dip galvanizing
- Can be used as a stand-alone coat or as a primer (with a compatible topcoat) in a duplex system
- Can restore cathodic protection of an existing galvanized coating or an existing RUST-ANODE® coating
