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.
