Nippon Paint 9000 Speed Undercoat: Fast-Drying High-Opacity Base

PRODUCT DESCRIPTION

Nippon Paint 9000 Speed Undercoat is a high-performance, quick-drying alkyd-based undercoat specifically engineered for projects requiring a fast turnaround. Known for its exceptional "build" and opacity, this undercoat effectively fills minor surface imperfections and provides a solid, uniform white base that enhances the color depth of the final gloss finish.

Designed for use on both wood and metal surfaces, 9000 Speed Undercoat is the ideal companion for the Nippon 9000 Gloss Finish series. Its superior leveling properties and ease of sanding make it a favorite for contractors looking to achieve a mirror-smooth finish in record time. Whether for interior or exterior applications, it ensures maximum adhesion and long-lasting durability for your topcoat.


 

TECHNICAL DATA (6-7 Points)

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

2. Color: White (Matte finish).

3. Specific Gravity: 1.40 – 1.50 kg/litre.

4. Solid Content: Approximately 72% by weight (48% by volume).

5. Drying Time (at 30°C):

   • Touch Dry: 30 minutes (extremely fast-set).

   • Hard Dry: 3 hours.

6. Theoretical Coverage: 10 – 12 m² per litre (at 35–40 microns Dry Film Thickness).

7. Overcoating Interval: Minimum 3 hours (allows for same-day topcoating).

APPLICATION INSTRUCTION

1. Preparation: Stir the paint thoroughly before use. This high-solids formula requires good agitation to ensure uniform density and opacity.

2. Application Methods:

   • Brush/Roller: Apply an even, generous coat. Thinning is generally unnecessary, but you may add up to 5% Nippon General Purpose Thinner for better flow on hot surfaces.

   • Conventional Air Spray: Thin with 10–20% General Purpose Thinner for a fine, atomized finish.

3. Sanding: Once hard dry (approx. 3 hours), the surface can be lightly dry-sanded with fine-grit sandpaper (P400) to achieve an ultra-smooth profile before the final gloss coat.

RECOMMENDED COATING SYSTEM

• For Wood Surfaces:

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

  • Undercoat: 1 coat of Nippon 9000 Speed Undercoat.

  • Topcoat: 2 coats of Nippon 9000 Gloss Finish.

• For Ferrous Metal Surfaces:

  • Primer: 1 coat of Nippon Red Oxide Primer or Zinc Phosphate Primer.

  • Undercoat: 1 coat of Nippon 9000 Speed Undercoat.

  • Topcoat: 2 coats of Nippon 9000 Gloss Finish.

SURFACE PREPARATION

1. Surface Cleaning: The substrate must be completely dry and free from all contaminants including grease, oil, dirt, and wax. Use a solvent wipe for oily residues.

2. Wood Substrates: Sand the wood surface along the grain to remove loose fibers. Ensure the moisture content of the wood is below 12% before application.

3. Metal Substrates: Remove all rust, mill scale, and old flaking paint using wire brushing or power tool cleaning to a minimum St 2 standard.

4. Existing Paint: For previously painted surfaces that are stable, lightly abrade the old gloss finish to create a "key" for the undercoat to bond to.

5. Environment: Do not apply the undercoat if the relative humidity is above 85% or if the surface temperature is less than 3°C above the dew point.
