Epoxy MIO Intermediate Coating (2K) – Two-component epoxy micaceous iron oxide intermediate coating for barrier protection.
For ships, containers, bridges, steel gates, gas holders, port machinery, and steel structures; used over zinc-rich primer or sprayed zinc.
Mix ratio 27:3; pot life 4 h (25°C).
Recoat 12 h–7 d (25°C); overcoatable with epoxy and polyurethane systems.
Overview
Two-component epoxy MIO anti-rust coating/intermediate coating providing barrier protection; the anti-rust pigment forms a “fish-scale” overlapping structure after film formation.
It can be used as a long-term anti-corrosion primer and as a reinforcing coat over zinc-rich primers or thermal sprayed zinc layers to improve sealing and corrosion resistance.
Composition
Epoxy resin, micaceous iron oxide powder, anti-settling agent, anti-rust agent, fillers, and solvents; polyamide curing agent; supplied as Part A and Part B.
Typical uses
Used with zinc-rich primers or thermal sprayed zinc layers to enhance sealing and corrosion resistance.
Applicable for ships, containers, bridges, steel gates, gas holders, port machinery, and various steel structures.
Technical data (typical)
Appearance / color: Gray or brownish.
Theoretical consumption: 0.14 kg/m² at 50 µm DFT (losses not included).
Density / specific gravity: 1.5 kg/L.
Drying / curing (25°C): Touch dry 1 h; hard dry 24 h; full cure 7 days.
Application data (25°C)
Mixing ratio (A:B): 27:3.
Induction time: 5 min.
Pot life: 4 h.
Application methods: Airless spray, brush, roller.
Thinner / Cleaner: X-7 epoxy thinner; typical dilution 2–8% (air spray/roller may require more).
Recoat interval / overcoating interval (25°C): Minimum 12 h; maximum 7 days.
Recommended DFT: 60–80 µm per coat (brush/roller: 30–50 µm per coat).
Surface preparation
When applied over a two-component primer: all surfaces must be clean, dry, and free of contaminants; if the maximum recoat interval is exceeded, surface roughening is required.
If used directly as the first coat: abrasive blasting to Sa 2.5 or power-tool cleaning to St 3; surface profile 30–75 µm.
System compatibility / packing / storage
Compatible topcoats: epoxy topcoat, polyurethane topcoat; also acrylic, chlorinated rubber, high chlorinated polyethylene, chlorosulfonated polyethylene, and chlorinated ether topcoats.
Shelf life: 12 months.
Storage: Store in a dry, cool, ventilated warehouse away from fire sources and direct sunlight; outdoor storage is not permitted.
Packaging: Part A 27 kg; Part B 3 kg.
