*For production line operation, baking curing is recommended to improve production efficiency. The maximum overcoating interval depends on the coating exposure environment and application.
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. Blast clean to Sa2½ with a surface profile of Rz 40–75 µm. Before derusting, remove all oil, grease and weld spatter, and grind welds and sharp edges. Where the coating film has suffered mechanical damage with localised rusting, spot blast to Sa2½ or power-tool clean to St3 before local repair of the primer. If the old film shows chalking or zinc salts, remove the zinc salts and contamination before applying the intermediate coat or topcoat.
1. 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 as well. 2. When mixing, first stir the base component uniformly, then add the curing agent in the specified ratio and mix uniformly. Adjust the thinner quantity according to application requirements and temperature variations, stir thoroughly and allow to induct. Filtration through a 120-mesh screen before use is recommended, and continuous stirring is required during use. 3. Strictly control application to achieve the recommended film thickness (6–15 µm, determined per GB/T6747-2008) to obtain satisfactory cutting efficiency and welding results. Thicker films provide longer protection time but affect welding, cutting and processing characteristics. Under most environments, a 10–15 µm film achieves a 6-month protection period. Excessive film thickness increases fume and dust during cutting and welding and reduces welding quality and cutting efficiency. Automatic application equipment is preferentially recommended for this product; if manual spraying is required, avoid dry spraying and excessive film thickness. 4. This product is only suitable for application on blast-cleaned steel surfaces and must not be applied over other types of coatings. Coatings with high acid value such as alkyd and alkyd-modified coatings must not be applied directly over this product's coating; otherwise, saponification and peeling of the coating may occur. 5. During application and curing, the substrate temperature must be above 5 °C and at least 3 °C above the dew point, and the relative humidity must not exceed 85%. 6. Cutting structures coated with this paint generates fume and dust; appropriate protection must be provided. 7. After long-term outdoor exposure (sunlight, rain) of this coating, chalking must be removed before applying subsequent coats; otherwise, intercoat adhesion will be affected. 8. This product is not suitable for underwater use. 9. When work is paused, do not leave paint in the paint line, spray gun or spray equipment. Thoroughly flush all equipment with thinner. If the pause is excessively long, remixing a fresh batch of paint for application is recommended. 10. All equipment must 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 duration, including interruption time and other factors. 11. Residual paint and empty cans must be disposed of in accordance with relevant regional regulations.

1. Refer to the safety data sheet and the safety data of related materials for the paint and recommended thinner. This is a solvent-borne paint; inhalation of paint mist and solvent must be avoided, skin and eye exposure should be minimized, and contact with wet paint must be avoided. 2. All work related to the application and use of this product must be carried out in accordance with all relevant national health, safety and environmental standards and regulations. 3. Welding or flame cutting on metal coated with this product generates dust and fume; therefore, use
appropriate personal protective equipment and adequate local ventilation. 4. If there are doubts regarding the suitability of this product, consult the company.
