Nippon Paint Micaceous Iron Oxide (MIO): Ultimate Corrosion Protection

PRODUCT DESCRIPTION

Nippon Paint Micaceous Iron Oxide (MIO) is a premium alkyd-based protective coating specifically formulated for the long-term preservation of steel structures. Infused with high-quality micaceous iron oxide pigments, this coating creates a unique "lamellar" (plate-like) barrier that effectively blocks moisture, oxygen, and UV rays from reaching the substrate.

Designed for both interior and exterior applications, Nippon MIO offers a sophisticated metallic matt finish that is as aesthetic as it is functional. It is highly resistant to atmospheric pollution, high humidity, and mild chemical fumes, making it the go-to choice for bridges, transmission towers, storage tanks, and industrial factories. Whether used as a standalone topcoat or an intermediate layer, it ensures your metal surfaces withstand the harshest environments.

TECHNICAL DATA 

1. Product Type: Single-pack, solvent-based alkyd coating.

2. Finish: Low Gloss / Metallic Matt Finish.

3. Specific Gravity: 1.60 ± 2.0% kg/litre (varies by colour).

4. Solid Content: Approximately 75% by weight (51% by volume).

5. Drying Time (at 30°C): * Touch Dry: 1 hour.

                                          * Hard Dry: 16 hours.

6. Theoretical Coverage: 8.5 – 10.2 m² per litre (at 50–60 microns Dry Film Thickness).

7. Overcoating Interval: Minimum 16 hours at 30°C.

APPLICATION INSTRUCTION

1. Mixing: Stir the paint thoroughly before use to ensure the heavy micaceous pigments are evenly distributed throughout the solution.

2. Application Methods: * Brush/Roller: Recommended for small areas and touch-ups. Thin up to 5% with Nippon General Purpose Thinner if necessary.

   • Spray: For large surfaces, use Airless Spray (Tip size: 0.015”–0.017”) or Compressed Air Spray (Thin up to 15% with General Purpose Thinner).

3. Environmental Conditions: Do not apply if relative humidity exceeds 85% or if the surface temperature is less than 3°C above the dew point.

RECOMMENDED COATING SYSTEM

• For Iron and Steel (Standard):

  • Primer: 1 coat of Nippon Zinc Phosphate Primer or Nippon Zinc Chromate Primer.

  • Finish: 2 coats of Nippon Micaceous Iron Oxide (MIO).

• For Non-Ferrous Metal (Galvanised/Aluminium):

  • Primer: 1 coat of Nippon Etching Primer 120 or Nippon Galvaprimer.

  • Finish: 2 coats of Nippon Micaceous Iron Oxide (MIO).

• For Wood:

  • Primer/Undercoat: 1 coat of Nippon 9000 Aluminium Wood Primer.

  • Finish: 2 coats of Nippon Micaceous Iron Oxide (MIO).

SURFACE PREPARATION

1. General Cleaning: Ensure the surface is completely dry and free from all contaminants including oil, grease, dirt, and wax.

2. Rust Removal: For steel surfaces, remove mill scale and rust by power tool cleaning (St 3) or abrasive blasting (Sa 2½) for maximum durability.

3. Sanding: Previously painted surfaces should be sanded to remove loose or flaking paint and to provide a "key" for the new coating to adhere to.

4. Degreasing: For new metal or oily surfaces, use solvent cleaning (SSPC-SP1) to ensure the primer can bond correctly to the substrate.

5. Compatibility Test: When applying over unknown old coatings, perform a "patch test" on a small area to ensure no lifting or wrinkling occurs before proceeding with the full application.
