Nippon Paint Micaceous Iron Oxide (MIO)

PRODUCT DESCRIPTION

Nippon Paint Micaceous Iron Oxide (MIO) is a high-quality, alkyd-based protective coating specifically formulated for the long-term protection of structural steel and iron surfaces. It contains lamellar (plate-like) micaceous iron oxide pigments that align parallel to the surface, creating a "shingle effect."

This unique physical structure forms an extremely tough, water-resistant barrier that shields the metal from UV radiation, moisture, and atmospheric pollutants. It is the industry standard for protecting outdoor structures such as bridges, transmission towers, gates, fences, and factory steelwork in aggressive environments.

TECHNICAL DATA

• Paint Type: Solvent-based (Alkyd)

• Finish: Low Gloss / Metallic Sheen

• Colors: Wide range (Standard MIO colors)

• Specific Gravity: 1.40 – 1.60 (varies by color)

• Theoretical Coverage: 8.5 – 10.2 m² per litre (at 40–50μm DFT)

• Drying Time (at 30°C):

  • Touch Dry: 2 hours

  • Hard Dry: 8 – 12 hours

• Recoating Interval: Minimum 8 hours

• Shelf Life: Up to 24 months in a tightly sealed container

• Pack Size: 1 Litre, 5 Litres

APPLICATION INSTRUCTIONS

• Mixing: Stir the paint thoroughly before and during application, as the heavy MIO pigments tend to settle at the bottom of the container.

• Thinning: Use Nippon General Purpose Thinner.

  • Brush/Roller: Ready to use (or thin with 5% if necessary).

  • Conventional Spray: Thin with 10–15% for better flow.

• Application Method: Brush, roller, or spray. For large steel structures, airless spray is recommended to achieve a uniform, high-build film.

• Cleaning: Clean all tools immediately with Nippon General Purpose Thinner after use.

RECOMMENDED COATING SYSTEM

For maximum durability on steel surfaces, use the following sequence:

1. Primer (1 Coat): Nippon Paint Red Oxide Primer or Nippon Paint Zinc Phosphate Primer.

2. Undercoat (1 Coat): Nippon Paint 9000 Undercoat (Optional).

3. Topcoat (2 Coats): Nippon Paint Micaceous Iron Oxide (MIO).

SURFACE PREPARATION

• New Steel: Ensure the surface is dry and free from oil, grease, and dirt. Solvent cleaning is recommended for oily surfaces.

• Previously Painted/Rusted Surfaces: Remove all loose rust, mill scale, and peeling paint using power tool cleaning (St 3) or abrasive blasting.

• Dryness: The substrate must be completely dry before application to ensure the MIO barrier forms correctly.

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