War Against Metal Corrosion: Industrial Primer Technologies

Oxidation (rust) is the cancer of metal. It is the desire of iron atoms to combine with oxygen and moisture to return to a lower energy state (iron oxide). When this process begins, the metal loses its structural integrity.

/Corrosion Mechanism Rust does not stay only on the surface; it progresses into the metal (pitting) and rots it. Especially in seaside (salt water) and industrial atmospheres, the corrosion rate increases 10 times.

/Renga Plus Defense Line 1. **Mechanical Cleaning:** Rusty surface must be cleaned to SA 2.5 level with wire brush or sandblasting. 2. **Anti-Rust Primer:** Barrier cutting metal's contact with air/water. Renga Plus Epoxy Rich Zinc Primer prevents the metal from sacrificing itself by providing cathodic protection. 3. **Top Coat Paint:** Layer protecting the primer from UV rays and giving aesthetics.

/DTM (Direct to Metal) Technology In slightly corrosive environments, you can save time and labor by applying directly to rusty surfaces (after rough rust is taken) with our DTM paints where primer and top coat are combined in a single can.
