Surfaces to be coated shall be clean, dry and free from contamination. Surface assessment and preparation shall follow ISO 8504. Oil
and removal of oil and grease in accordance with the SSPC-SP1 solvent cleaning standard.
Repair of damaged areas: damaged areas shall be abrasive blast cleaned to Sa 2½ (ISO 8501-1:2007). Where blasting is not possible locally, mechanical grinding to St3 (ISO 8501-1:2007) is permitted. After surface preparation meets the specified requirements, repair shall be carried out in sequence according to the coating system.
HI-FLORO 6738HS Fluorocarbon Topcoat shall be applied to substrate surfaces in accordance with the anticorrosive coating system recommended by Nippon Paint.
Ensure the surface to be coated is clean and dry before application, and application must be carried out within the specified recoat interval (refer to the application instructions of the relevant product).
Other surfaces: if this coating is to be applied to other surfaces, consult the local Nippon Paint company for further information.
Application is not recommended when ambient temperature exceeds 45°C or relative humidity exceeds 85%; steel temperature must be at least
3°C above the ambient dew point. To achieve optimum film performance, the curing temperature should be controlled above 10°C.
| Mixing ratio | Base : curing agent = 9:1 (by volume) |

The base and curing agent must be thoroughly mixed before use.
| Pot life | 2 h (25 °C) |

Once mixed, use within the pot life.
| Theoretical Spreading Rate | 12 m²/L (at 50 µm dry film) |
|---|---|
| Thinner | Thinner 0961 (slow-drying) (suitable for winter and summer) |
Thinning shall not exceed the limits permitted by local regulations.
Roller/brush/air spray: for touch-up and small-area application;
Airless spray/air spray: recommended for large-area application;
Regardless of the method used, the specified dry film thickness must be achieved.
| Airless Spray | Nozzle size: 0.015–0.021 in; nozzle pressure: 100–150 kg/cm² |

| Touch dry time | 4h | 3.5h | 3h | 0.5h | 0.3h |
| Hard dry time | 9h | 8h | 7h | 4h | 2h |
| Minimum recoat time | 9h | 8h | 7h | 4h | 2h |
| Maximum recoat time* | - | ||||
Note*: the surface shall be free of chalking and contamination before recoating; extended outdoor exposure of the film, a smooth surface or contamination will adversely affect recoat adhesion, so the film surface must be abraded, sweep-blasted or high-pressure water jetted to ensure adequate adhesion.
The data above are for guidance only. Actual recoat and drying times may be shorter or longer depending on film thickness, ventilation, humidity, the underlying coating system, and prior hand or mechanical preparation conditions.

Note: packaging can be switched to kg as required.
| Shelf life (from date of production) | Base: 12 months (25 °C) |
|---|
Curing agent: 12 months (25 °C). Store in accordance with national regulations. Keep the product sealed in a dry, cool, well-ventilated store away from heat and sources of ignition. High temperatures shorten the storage period and may cause the paint to gel in the container. The above is the minimum shelf life; thereafter, testing is required to confirm the product is still usable.
