Epoxy Micaceous Iron Oxide Intermediate Coat

Winsir Epoxy Micaceous Iron Oxide Intermediate Coat uses epoxy resin as the base. Micaceous iron oxide (MIO) is the main anti-corrosion pigment. The flake structure of MIO creates a "labyrinth effect." This significantly extends the penetration path for corrosive media. It enhances the overall anti-corrosion life of the coating system. Salt spray resistance exceeds 1000 hours per ISO 12944 C5-M environment. This epoxy micaceous iron oxide intermediate coat has better UV resistance than ordinary epoxy paints. It can be exposed outdoors for up to 3 months without a topcoat.

Winsir Epoxy Micaceous Iron Oxide Intermediate Coat offers excellent adhesion and chemical resistance. It is compatible with epoxy zinc rich primers and inorganic zinc primers. It works well with acrylic polyurethane topcoats and fluorocarbon topcoats for long-lasting systems. For construction, this epoxy micaceous iron oxide intermediate coat allows thick application. Single coat dry film thickness reaches 80 to 120 µm. This reduces the number of coating passes. Tack-free time is 30 minutes or more at 25°C. Hard drying takes 24 hours or more. This shortens project timelines.

Winsir Epoxy Micaceous Iron Oxide Intermediate Coat is used in heavy-duty anti-corrosion applications. These include marine engineering, ship decks, offshore platforms, military equipment, bridges, and petrochemical storage tanks. It is also used on outdoor steel structures, transmission towers, and port machinery. For refurbishment, it works for old coating repairs after sanding to St3 grade. A classic system includes epoxy zinc rich primer at 60 µm, this epoxy micaceous iron oxide intermediate coat at 150 µm, and polyurethane or fluorocarbon topcoat at 50 µm. This system provides over 10 years of corrosion protection.
