Premium Paint - NIPPON PAINT PU UNDERCOAT WHITE

Premium Paint - NIPPON PAINT PU UNDERCOAT WHITE

1. Product information:

- Nippon Paint PU UNDERCOAT WHITE is a polyurethane-based oil with two componentsbeing the result the reaction between acrylic and isocyanate. This paint is used as a middle coat for interior and exterior surfaces such as: Ferrous and non-ferrous metals iron, wood, plastic, plastered walls, concrete, already primed, and so on.

- Characteristics:

    + Color: White

    + Finish: Glossy

    + Density: 1.22 ± 0.05 (for mixture of base and curing agent)

    + Solid content: 42 ± 2 by volume (for mixture of base and curing agent)

    + Abrasion: the paint film, after completely drying, has high hardness, and strong resistant abilities for abrasion and impact

    + Adhesion: Very good adhesion on well-prepared surfaces. Adhesion problems do not occur under normal conditions

    + Temperature: In dry conditions, can withstand 100oC

- Advantage:

• Anti mold
• Excellent adhesion on old surface being painted with epoxy or polyurethane
• Non-toxic and easy to use
• Create a solid base for the next coat of paint
• Easy to apply with ordinary spray gun

2. Applying process:

▶ Preparation:

- Soft steel:

    + Sanding the surface according to Swedish standard SA 2.5 or if you want it better, you can do it according to SA 3.0 standard (SIS 05 59 00/ISO 8501-1). Adding a prime layer immediately with a suitable primer and then cover with a suitable middle coat.

    + If the steel surface changes color or there is rust, the surface must be blown again. Surface must be dried and cleaned, which is free from dust, stains, oil and other contamination before painting

- Galvanized steel:

    + New galvanized surfaces require cleaning according to SSPC-SP1. For old galvanized steel surfaces, scrub the surface to remove any other impurities remaining on the surface. Then, adding primer immediately. All surfaces must be dry, oil-free, and grease before painting.

- Plastered walls, concrete, asbestos, cement:

    + Surface humidity must be less than 6% (by Sovereign moisture meter). Unstable substances such as powder, old paint film, stains and unstable mortar should be cleaned with high pressure water or a suitable scraper such as a brush.

    + High pressure water should be used for exterior wall surfaces. You must wipe it in wet condition. Oil or grease must be cleaned by a solvent or mild detergent. After allowing the surface to dry thoroughly, apply a 40-50% diluted of Nippon EP4 Clear - the primer.

▶ Wood:

    + Surface humidity must be less than 10% (by Sovereign moisture meter). Sand and clean the surface to make it smooth, then add primer with suitable paint no.ق. Recommended number of paint layers: - 1 - 2 layers

3 .Recommended thickness:

    + 40 microns for dry paint layer

    + 96 microns for wet paint layer

4. Theoretical coverage:

- 10.4 m2/liter ( 40 microns thickness for dry paint layer)

5. Construction technique:

- Brush, roller, spray gun with or without air

6. Diluting method:

- Spray with gas:

    + Pressure (kg/cm2): 3-4

    + Size of nozzle at 60o angle: 1.3mm

- Spraying without air:

    + Pressure (kg/cm2): 140-170

    + Nozzle size at 60o angle: 0.015” – 0.017”

7.Dilutiing conditions:

- Brush & roller: up to 10%

- Airless spray: up to 25%

- Spray without air: up to 5%

8.Mixing Ratio:

- 9 times of in PU UNDERCOAT WHITE (Base) with 1 time for the solidifying UNDERCOAT HARDENER PU  by volume.

- Blend the base. While stirring slowly, add the hardener and continue stirring unti we have a well-blended mixture. Diluting stage is after the base and solidifying substance have been mixed

9. Using duration of the mixed mixture at 25°C to 30°C:

- 6 - 8 hours

10. Diluent solvent:

- Nippon Paint PU Thinner

11. Sanitizing solvents:

- Nippon Paint PU Thinner
