2K C6-modified epoxy MIO intermediate coat engineered to extend coating service life on marine and offshore structures. Pairs with epoxy zinc primer for layered cathodic and barrier protection. 50µm DFT, Sa2.5 prep.
PLH53-10 Epoxy MIO Intermediate Coating is a two-component, polyamide-cured epoxy micaceous iron oxide (MIO) intermediate coating modified with special C6-element material (sp2 hybridization).
The product is formulated with epoxy resin, micaceous iron oxide powder, anti-settling agent, toughening agent, and solvent, and is modified with special C6-element material (sp2 hybridization). It is supplied as two components with a polyamide curing agent.
Two-component, polyamide-cured epoxy MIO intermediate coating
Specified for use with epoxy zinc primer as a supporting coat
Combines cathodic protection synergy with barrier performance for corrosion protection
Can be applied by airless spray, brush, or roller

| Item | Details |
|---|---|
| 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) |
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.
