All surfaces to be coated shall be clean, dry and free from contaminants. Prior to application, all surfaces shall be assessed and prepared in accordance with ISO 8504:2000. Blast clean to Sa2½ with a surface profile of 40~75µm. Before derusting, remove all oil and grease and welding spatter from the surface and grind welds and sharp edges. Where a coating of this product has suffered mechanical damage and local rusting, local blast cleaning to Sa2½ or power tool cleaning to St3 is required before local repair with this primer. If chalking or zinc salts appear on the surface of an old coating film, remove the zinc salts and contaminants from the surface before applying other primers, intermediate coats or topcoats.
1. Provide ventilation and exhaust during application, keep away from ignition sources, and wear protective equipment such as masks and gloves; maintain adequate ventilation during curing. 2. Stir the zinc dust slurry uniformly with a power tool, add the curing agent and mix thoroughly; adjust the amount of thinner according to application requirements and temperature changes and mix thoroughly; filtration through a 120-mesh screen is recommended before use, and continuous agitation is required during use. 3. The maximum coating film permitted for this product is 120 µm; excessive film thickness may cause cracking. Pay attention to the treatment of edges and corners of the coated components and to excessive film thickness during application to avoid cracking. 4. This product is suitable only for application to blast-cleaned steel surfaces and inorganic zinc silicate coating surfaces; it shall not be applied over other types of coatings. Substrates with excessively low roughness or smooth surfaces will not provide good adhesion and the coating may even detach. 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 shall not exceed 85%. Temperature and relative humidity shall be measured at the substrate near the work area. Maintain good ventilation in the application environment, with a relative humidity not below 60%. If the humidity is below 60% during actual application, water spraying for humidification is required, and the degree of cure shall be assessed in accordance with ASTM D4752 before recoating, reaching at least grade 4. A fast-drying curing agent may be selected in seasons of low humidity and low temperature. 6. When the product is used alone in systems resistant to oils, solvents and chemicals, the coating thickness shall not exceed 90 µm. The permissible pH range of the media is 6-9. Assess the degree of cure in accordance with ASTM D4752, reaching grade 5. 7. Cutting structures coated with this product generates fumes and dust; appropriate protection shall be provided. 8. When applying other coatings over this product, sealing shall be carried out in advance; a dedicated sealer primer is recommended, or the subsequently applied epoxy coatings may be thinned and mist-coated for sealing to avoid blistering. Alkyd, alkyd-modified, polyurethane and similar coatings shall not be applied directly over this product. 9. When work is suspended, do not leave coating in the paint line, spray gun or spray equipment. Flush all equipment thoroughly with thinner. If the suspension is prolonged, mixing a fresh batch of paint for application is recommended. 10. Clean all equipment with thinner immediately after use. Periodic flushing of spray equipment during the working day is good practice. Cleaning frequency depends on spray volume, temperature, spray time, including interruption time and other factors. 11. Residual paint and empty containers shall be disposed of in accordance with the relevant local regulations.

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.
