Surface Preparation

Before application, blast-clean the substrate to Sa 2.5 (ISO 8501-1) and apply a suitable primer. Remove grease with a suitable cleaning agent and wash off salts and other contaminants with high-pressure clean water. Repair any damage to the anti-rust primer before applying the fire protection coating. On steel already coated with anti-rust primer, check the compatibility between the primer and the fire protection coating.

Precautions

1) During application, the steel surface temperature must be 10–45 °C. The surface temperature must be at least 3 °C above the dew point and the maximum relative humidity must not exceed 85% during application. During application, ensure ventilation and exhaust, keep away from ignition sources, and wear protective equipment such as masks and gloves; maintain adequate ventilation during curing. 2) This product can be thinned as required by adding tap water; mix thoroughly and strain through a 120-mesh copper screen before use. Seal unused paint that will not be used for a long time, otherwise skinning may occur. If skinning occurs, strain out the skin before use. 3) To achieve full performance, reaching the specified dry film thickness is essential. The dry film thickness also depends on the shape and size of the steel. The applicator must ensure all areas of the steel reach the specified dry film range. Whether by airless spray or brush/roller, the fire protection coating must be applied in multiple coats to reach the specified dry film thickness. For the first coat, thin the coating and control the thickness at 0.30–0.50 mm; apply the next coat after drying for more than 6 hours (20 °C, 65% RH), controlling at 0.40–0.70 mm. Before applying the topcoat, the fire protection coating must dry for at least 48 hours. 4) Apply only over primers approved by the company; consult the company's technical representative regarding approved primers. This product is supplied in white only. Depending on the purpose of the system, a compatible approved topcoat may be required; consult the company's technical representative on which topcoat to use. 5) This product has a high viscosity and may show false-body (thixotropic) thickening in storage. Stir briefly before application to mix evenly and break the false body, ensuring good flow during application; excessive stirring may cause solvent loss. The product is thermoplastic and ductile; above 40 °C the film may show indentation under mechanical action, and the mechanical strength recovers when the temperature drops. 6) During work breaks, do not leave paint in the hose, spray gun or spray equipment. Flush all equipment thoroughly with thinner. 7) Clean all equipment with thinner immediately after use. Flushing spray equipment regularly during work is good practice. Cleaning frequency depends on spray volume, temperature and spraying time including interruptions. 8) The fire protection coating must not be exposed to rain during application and curing; handle with care. Before and during use, avoid inhaling spray mist and minimise skin and eye exposure, and avoid contact with wet paint. Without a topcoat or temporary waterproof layer, the fire protection coating has only limited water resistance. Move the coated item outdoors for curing only after a topcoat or temporary waterproof layer is applied. 9) Dispose of leftover paint and empty cans in accordance with local 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 thinners, refer to the safety data sheet and related material safety data. Although this is a water-borne coating, avoid inhaling spray mist and minimise skin and eye exposure, and avoid contact with wet paint. 2) All work related to the application and use of this product must comply with the relevant national health, safety and environmental standards and regulations. 3) Welding or flame cutting on metal coated with this product produces dust and fumes; use appropriate personal protective equipment and adequate local ventilation. 4) If in doubt about the suitability of this product, consult the company.
