What is BANNOH 1500 RZ PART A and why choose it
BANNOH 1500 RZ PART A is the base component of BANNOH 1500 R Z, a high-solids, two-pack epoxy anticorrosive tie coat from Chugoku. Designed for professional marine use, it is applied together with the corresponding hardener to form a tough, abrasion-resistant film with excellent resistance to fresh and sea water.
This binder coat is optimised for use between anticorrosive primers and antifouling systems on ship hulls and also works as an anticorrosive coating for decks and superstructures. Its smooth surface and low Friction Increase Ratio (FIR) help maintain vessel efficiency while offering reliable overcoatability with a wide range of Chugoku antifoulings and finishes.

FAQ
Is BANNOH 1500 RZ PART A a standalone product?
No. BANNOH 1500 RZ PART A is the base component of a two-pack epoxy system and must always be mixed with the specified hardener (BANNOH 1500 R Z Hardener) in a ratio of 81:19 by volume.
Where is this product typically used on a vessel?
It is used as a binder coat on exterior hulls between anticorrosive primers and antifouling paints, and as an anticorrosive coating on decks and superstructures.
What are the recommended application methods?
Professional application by airless spray is recommended for most areas. Brush or roller can be used for stripe coats, small areas or touch-up; in these cases additional coats may be necessary to reach the specified film thickness.
What is the minimum steel temperature for application?
The minimum recommended substrate temperature is -5 °C, provided it is at least 3 °C above the dew point and the relative humidity does not exceed 85%.
Which thinner should be used?
Use EPOXY THINNER A (and, where specified, EPOXY THINNER G), with a thinning ratio of 0–15% by volume depending on application conditions.
Can it be applied in confined spaces?
Yes, but confined spaces such as tanks and voids must be well ventilated during application and curing to remove vapours and promote proper curing.
Is BANNOH 1500 R Z BASE classified as flammable?
Yes. According to its safety data, it is classified as a flammable liquid, with a flash point of 25 °C for the mixed product.
What about environmental hazards?
The base component is classified as harmful to aquatic organisms with long lasting effects. Avoid release to the environment and handle waste according to local regulations.

Section 8 – Personal protection measures
Key exposure control and personal protective equipment (PPE) requirements for handling BANNOH 1500 R Z BASE, summarised from Section 8 of its Safety Data Sheet:
Engineering controls
- Provide adequate general and, where necessary, local exhaust ventilation to keep solvent vapour and spray mist below occupational exposure limits.
- When dry sanding, cutting or welding on the dry film, avoid dust and fumes; use wet methods where possible or local exhaust plus respiratory protection.
Respiratory protection
- When exposure may exceed limits, use a half-mask respirator complying with EN 140 fitted with combined particulate and organic vapour filters in accordance with EN 14387 (for example A2P3) with a protection factor of at least 10.
Hand protection
- Use chemical resistant gloves tested according to EN 374.
- Recommended materials for repeated or prolonged contact:
- Polyethylene (PE) gloves, minimum thickness 0.062 mm.
- Viton/butyl rubber gloves, typical thickness around 0.70 mm.
- For splash or short-term exposure: PE gloves (0.062 mm) and/or Viton/butyl gloves; nitrile gloves can also provide good resistance depending on thickness.
- Inspect gloves before use, replace regularly and immediately if damaged. Use PE under-gloves beneath other gloves in challenging conditions such as high exposure or unknown composition.
Eye and face protection
- Wear safety goggles or face shield designed to protect against liquid splashes, conforming to EN 16321 or EN 166.
Skin and body protection
- Wear antistatic protective clothing made from natural fibres or heat-resistant synthetic fibres (EN ISO 13688).
- Avoid contact with skin; do not use solvents to clean paint from skin. Wash with lukewarm water and soap or suitable skin cleaner.
General safety and hygiene measures
- Keep away from heat, hot surfaces, sparks and open flames. No smoking.
- Avoid breathing vapours, spray mist or sanding dust.
- Do not eat, drink or smoke in the application area.
- Store containers tightly closed in a dry, well-ventilated place between 0 and 40 °C, away from direct sunlight and oxidising, strongly acidic or strongly alkaline materials.
- Prevent the product from entering drains or watercourses.
