*The maximum recoat interval depends on the exposure environment and the end use of the coating.
All surfaces to be coated shall be clean, dry and free from contamination. Before application, all surfaces shall be assessed and prepared in accordance with ISO 8504:2000. Where the coating film has suffered mechanical damage with localised rusting, it shall be abraded, filled or otherwise treated. The surface quality may be reduced to Sa2, but loose powdery deposits shall not be present.
1. During application, ensure ventilation and exhaust, keep away from sources of ignition, and wear protective equipment such as a mask and gloves; maintain adequate ventilation also during curing. 2. Adjust the thinner quantity according to temperature, mix thoroughly, and filter through a 120-mesh copper screen before use. Seal unused paint if not used for a long time, otherwise skinning occurs; if skinning occurs, remove the skin before use. 3. The film thickness may be adjusted according to the intended use and area. This will alter the spreading rate, drying time and recoat interval. The normal dry film thickness range is 60–100 µm. Repeated maintenance may make the total film too thick, causing blistering. As each coat may retain solvent, avoid applying this product too thickly. 4. As this product is thermoplastic, prolonged mechanical load above about 40 °C will indent the film. Once the temperature falls, the mechanical strength of the film recovers. 5. During application and curing, the substrate temperature must be above 5 °C and at least 3 °C above the dew point, with relative humidity not more than 85%. Temperature and relative humidity must be measured on the substrate near the work area. 6. Cutting of structures coated with this product produces fume; take appropriate protection. 7. When work is interrupted, do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. 8. Clean all equipment immediately after use with thinner. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature, spraying time, including interruptions, and other factors. 9. Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.

Keep sealed in a ventilated, cool, dry place away from sources of ignition. Minimum 12 months.
1. For the coating and its recommended thinners, see the safety sheets and the safety data of the relevant materials. This is a solvent-borne coating; avoid inhaling spray mist and solvent vapours, and avoid exposing skin and eyes and contact with uncured paint as far as possible. 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. If welding or flame cutting is required on metal coated with this product, dust and fumes will be generated; use appropriate personal protective equipment and adequate local ventilation. 4. If in doubt about the suitability of this product, consult the company.
