BANNOH 1500 PART A

What is BANNOH 1500 PART A and why choose it

BANNOH 1500 PART A from Chugoku is the base component of BANNOH 1500, a multi-purpose high solid epoxy primer designed for demanding marine environments. It delivers excellent toughness, abrasion resistance and adhesion, together with outstanding flexibility and resistance to sea water and cathodic protection.

Approved as an IMO PSPC coating for water ballast tanks and cargo oil tanks, BANNOH 1500 can be used as a universal primer on most areas of a ship, from hull and boot-top to decks, superstructures and cargo spaces. It is also FDA-approved for dry solids and recognised by Lloyd’s as an abrasion resistant ice class coating for ice classifications PC6, PC7 and 1A Super to 1A. These certifications make BANNOH 1500 PART A an ideal choice where long-term corrosion protection, regulatory compliance and easy cleaning between cargoes are critical.

FAQ – BANNOH 1500 PART A

1. What is BANNOH 1500 PART A used for?

   It is the base component of a high-solids epoxy primer used as an anti-corrosive coating on ship hulls, decks, superstructures, ballast water tanks, cargo oil tanks and holds.

2. How should BANNOH 1500 PART A be mixed?

   Mix BANNOH 1500 PART A (Base) with its designated hardener at 79:21 by volume. Agitate the base with a power agitator until homogeneous, then add the entire hardener while mixing and continue mixing thoroughly before adding thinner.

3. Which thinner should I use and how much?

   Use EPOXY THINNER A. For airless spray, typical thinning is 0–20% by volume depending on conditions and equipment.

4. What application methods are recommended?

   The coating can be applied by airless spray, brush or roller. When using brush or roller, additional coats may be required to achieve the specified dry film thickness.

5. What are the minimum application conditions?

   Apply at steel and ambient temperatures of at least 0°C, with maximum relative humidity of 85% and the surface temperature at least 3°C above the dew point.

6. How long before the coated surface can be walked on or immersed?

   At 20°C and 160 µm DFT, the coating is typically hard dry in about 9 hours; full mechanical strength and walk-on capability follow after hard dry. Minimum times before water immersion are around 3.5 days at 20°C and longer at lower temperatures.

7. Is BANNNOH 1500 suitable for ballast water and cargo oil tanks?

   Yes. BANNOH 1500 is IMO PSPC type approved for water ballast tanks and cargo oil tanks and carries FDA approval for dry solids.

8. Can it be overcoated with other Chugoku systems?

   Yes. It can be overcoated with products such as ACRI 700 FINISH, EPICON MARINE FINISH, UNY MARINE HS M, BANNOH 1500 QD, BANNOH 1500 R Z, SILVAX SQ-K, CMP AC and PERMAX series coatings within the specified maximum intervals.

9. How should surfaces be prepared before application?

   Remove oil, grease, salts and contaminants by high-pressure fresh water cleaning and drying. Damaged steel should be abrasive blast cleaned to Sa2 minimum or power tool cleaned to St3 where blasting is not possible, following standard marine specifications.

10. Is ventilation required during curing?

    Yes. In confined spaces such as tanks and void spaces, continuous ventilation is required during application and curing to remove solvent vapours and promote proper curing.

Section 8 – Personal protective measures (summary)

Exposure controls

• Engineering controls: Provide adequate ventilation using local exhaust and general extraction to keep solvent vapour and particulate concentrations below occupational exposure limits. In spray booths or enclosed areas where this is not sufficient, use appropriate respiratory protection.

Individual protection equipment

• Respiratory protection: If exposure may exceed limits, use a respirator conforming to EN 140 fitted with a combined filter for particulates and organic vapours to EN 14387, with an assigned protection factor of at least 10 (e.g. A2P3). For work inside spray booths where ventilation is insufficient, a compressed air-fed respirator is recommended during spraying and until vapour/particulate levels fall below limits.
• Hand protection:
  • Use chemical-resistant gloves tested according to EN 374.
  • Suitable materials include Polyethylene (PE) gloves and Butyl/Viton gloves, which provide high chemical resistance for repeated or prolonged exposure.
  • Nitrile gloves offer good protection during spray application.
  • Use PE gloves underneath other gloves in high-exposure or uncertain chemical situations.
  • Replace gloves regularly and immediately if any damage or degradation is observed.
• Eye and face protection: Wear safety eyewear to EN 16321 / EN 166 designed to protect against liquid splashes (e.g. safety goggles or face shield).
• Skin and body protection: Wear anti-static protective clothing made from natural fibre or high-temperature-resistant synthetic fibre (EN ISO 13688). Avoid skin contact; do not use solvents or thinners for skin cleaning—wash with soap and water instead.

Environmental exposure controls

• Prevent releases to drains, sewers or watercourses. In case of spillage, contain and collect with non-combustible absorbent material and dispose of according to local regulations.
