PRODUCT DESCRIPTION

Nippon Paint EA7 Finish is a high-performance, two-pack amine-adduct cured epoxy coating specifically designed for internal use. It provides a beautiful semi-gloss finish that balances aesthetic appeal with exceptional functional durability.

This coating is highly resistant to abrasion, impact, and a broad spectrum of chemicals, including oils, solvents, and mild acids. It is the go-to solution for high-traffic environments that require a cleaner look than a standard matte finish, such as showrooms, commercial offices, laboratories, and light-industrial warehouses. Its smooth surface ensures ease of maintenance while providing a long-lasting protective barrier for concrete and masonry.

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

APPLICATION INSTRUCTIONS

• Mixing: Stir the Base (Part A) thoroughly. Add the Hardener (Part B) and mix until the color and consistency are completely uniform. Allow an induction time of 10–15 minutes before application.

• Thinning: Use Nippon SA-65 Thinner.

  • Brush/Roller: Add 5–10% thinner if necessary.

  • Conventional Spray: Add 10–20% thinner.

• Application Method: A short-nap mohair roller is preferred for large floor areas to achieve a uniform semi-gloss appearance. Brush is suitable for edging and small sections.

• Cleaning: Clean all tools immediately with SA-65 Thinner after use.

RECOMMENDED COATING SYSTEM

For a professional and long-lasting result on concrete surfaces:

1. Primer (1 Coat): Nippon Paint Aqua Epoxy Primer or Nippon Paint Penetrative Epoxy Primer.

2. Finish (2 Coats): Nippon Paint EA7 Finish.

SURFACE PREPARATION

• New Concrete: Must be cured for at least 28 days. The surface must be dry (moisture content < 4%) and free from laitance, dust, and curing compounds.

• Cleaning: Remove all oil, grease, and contaminants using a degreaser or detergent. For smooth concrete, mechanical grinding or light acid etching is recommended to ensure a proper mechanical bond.

• Old Paint: Remove all loose, peeling, or unstable paint films. Lightly sand existing sound epoxy coatings to provide a "key" for the new layer.

• 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.
