Application Data (typical DFT 750µm):

The drying times listed in the above table are measured at a typical thickness of 750 µm under controlled temperature and relative humidity of 50%~75% with good ventilation.

*The maximum overcoating interval depends on the exposure environment and use of the coating, and normally shall not exceed 12 months.

Surface Preparation

• All surfaces to be coated shall be clean, dry and free from contamination. Before coating, all surfaces shall be assessed and prepared according to ISO

8504:2000. If grease is present, clean with solvent according to SSPC-SP1.

• Before application of this product, the substrate shall be blast cleaned to Sa2½ (ISO8501-1) and a suitable primer applied. Use a suitable

cleaner to thoroughly remove grease, etc., and high-pressure clean water to remove salts and other contaminants. Steel must be coated with a primer approved by the company. Where conditions are limited, mechanical grinding to St3 is also acceptable; see the relevant requirements in the application guide.

• Zinc-sprayed surfaces, thermal aluminium-sprayed surfaces or stainless steel substrates require different surface preparation; for details, please refer to the application

guide.

Precautions

1. The steel surface temperature during application of this product shall be 5~50 °C. The surface temperature must be at least 3 °C above the dew point, and the maximum relative humidity during application must not exceed 85%; ensure ventilation and exhaust during application, keep away from ignition sources, wear masks, gloves and other protective equipment, and maintain adequate ventilation during curing. 2. This product may be diluted as required, but excessive thinner will cause a risk of sagging; adjust the thinner amount according to temperature changes, mix thoroughly, and filter through a 120-mesh copper wire screen before use. Unused paint must be sealed when not used for a long period, otherwise skinning may occur. If skinning occurs, filter out the skin from the paint before use. 3. To ensure full performance of this product, it is important to achieve the specified dry film thickness. The dry film thickness of this product also depends on the shape and dimensions of the steel. Applicators must ensure that all areas of the steel reach the specified dry film range. Whether by airless spray or brush/roller, the fireproof coating must be applied in multiple coats to achieve the specified dry film thickness. For the first coat, dilute the fireproof coating to a film thickness of 0.25~0.35mm, and allow to dry for more than 6 h (20 °C, relative humidity 65%) before applying the next coat. It is recommended that the typical dry film thickness per spray coat is 750 µm (undiluted), and the maximum dry film thickness per roller coat is recommended to be 400 µm (undiluted). Applying higher film thickness may easily cause sagging and unacceptable solvent retention. 4. According to regulations, apply only over a primer approved by the company; please consult the company's technical representative regarding approved primers. This product is available only in white; depending on the purpose of the coating system, a coat of this product may be required

Compatible and approved topcoats; consult the company's technical representative regarding the selection of a topcoat for specific conditions. 5. This product has high viscosity and exhibits false body during storage. Stir briefly before application to mix uniformly and break the false body, ensuring good flow during application; excessive stirring may cause solvent evaporation. This product is thermoplastic and ductile; at temperatures above 40 °C, the film may show marks under mechanical action, and mechanical strength recovers when the temperature decreases. 6. When work is suspended, do not leave paint in the paint line, spray gun or spray equipment. Flush all equipment thoroughly with thinner. 7. All equipment shall be cleaned with thinner immediately after use. Periodic flushing of spray equipment during the daily work process is good practice. Cleaning frequency depends on spray volume, temperature, spray time, including interruption time and other factors. 8. Fire-retardant coatings shall not be exposed to rain during application and curing; handle with care. Before and during use, inhalation of paint mist must be avoided, skin and eye exposure shall be minimized, and contact with wet paint shall be avoided. Without a topcoat or intermediate waterproof layer, the fire-retardant coating has only limited water resistance. The fire-retardant coating may be moved outdoors for curing only after a topcoat or temporary waterproof layer has been applied. 9. Residual paint and empty containers shall be disposed of in accordance with applicable regional regulations.

Packaging

20 kg/drum

Storage

Keep sealed in a ventilated, cool, dry place away from sources of ignition. Minimum 12 months.

Safety Precautions

1. For the paint and recommended thinner, refer to the safety data sheet and the safety data of the relevant materials. Although this is a water-borne paint, inhalation of paint mist must still be avoided, skin and eye exposure shall be minimized, and contact with wet paint shall be avoided. 2. All work related to the application and use of this product must be carried out in accordance with the relevant national health, safety and environmental standards and regulations. 3. Welding or flame cutting on metal coated with this product generates dust and fumes; suitable personal protective equipment and adequate local ventilation are therefore required. 4. If there is any doubt about the suitability of this product, consult the company.
