Epoxy MIO intermediate coating (2K) for barrier protection in cathodic-protection coating systems.
Used with PLH53-35 epoxy zinc primer as a supporting intermediate coat.
Salt water resistance: 20 days (as stated).
Mixing ratio 8:1 (by weight); recommended DFT 60–90 µm per coat.
Overview
Two-component, polyamide-cured epoxy micaceous iron oxide (MIO) intermediate coating modified with special C6-element material (sp2 hybridization).
It is specified for use with PLH53-35 epoxy zinc primer as a supporting coat, combining cathodic protection synergy with strong barrier performance for corrosion protection.
Composition
Epoxy resin, micaceous iron oxide powder, anti-settling agent, toughening agent, and solvent; modified with special C6-element material (sp2 hybridization); polyamide curing agent; supplied as two components.
Typical uses
Ship repair/building, bridges, petrochemical facilities, steel structures, offshore platforms, underwater steel structures, pipelines, and oil tanks; used in cathodic-protection coating systems.
Technical data (typical)
Appearance / color: Gray.
Theoretical consumption: 0.14 kg/m² at 50 µm DFT (losses not included).
Density / specific gravity: 1.53 kg/L.
Drying / curing (25°C): Touch dry 1 h; hard dry 24 h; full cure 7 days.
Salt water resistance: 20 days.
Application data (25°C)
Mixing ratio (A:B): 8:1 (by weight).
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 24 h; maximum 7 days.
Recommended DFT: 60–90 µm per coat (brush/roller: 35–50 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: polyurethane topcoat, fluorocarbon topcoat, etc.
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.
