*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. The product may be applied directly to metal substrates prepared to Sa2½ or St3, or over the recommended heat-resistant anticorrosive primer. When used over a heat-resistant primer, it shall be applied within the specified overcoating interval, and the primer surface shall be dry and free from contamination. When applied over other heat-resistant old coatings, chalk, grease and other contaminants shall be removed by appropriate methods. In cracked or damaged areas, the substrate shall be prepared to Sa2½ or St3 and the primer repaired before applying the product.
1. During application, ensure ventilation and exhaust, keep away from ignition sources, and wear masks, gloves and other protective equipment; adequate ventilation shall also be maintained during curing. 2. When mixing paint, first stir the paint uniformly, add the hardener in the specified ratio and stir uniformly, then adjust the thinner amount according to application requirements and temperature changes, and stir thoroughly. As the product ratio is large, weighing instruments shall be used when the mixing quantity is small; volumetric measuring devices cannot accurately prepare the paint by volume. 3. The film may show slight discolouration and yellowing when exposed to high temperature for a long time. The maximum heat resistance temperature depends on the dry film thickness of the coating; the lower the thickness, the higher the maximum heat resistance temperature. 4. Excessive coating thickness or too short a recoating interval will seriously affect the drying and curing, heat resistance, recoating performance and handling time of the coating. 5. After long-term exposure of the product coating, before recoating, ensure that the old film surface is free of contaminants and sand the surface before applying subsequent coatings. 6. When applied over inorganic zinc silicate primer, ensure the primer is fully cured (MEK test at least grade 4). 7. Thick films of this product must be thoroughly dried and cured for at least 14 days before being put into service; otherwise, the incompletely cured coating cannot achieve good temperature resistance, and the film may peel or detach during heating. 8. 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%. Avoid application on surfaces above 40°C; otherwise defects such as blistering and poor levelling are likely to occur. 9. Cutting structures coated with this paint generates fumes and dust; appropriate protection shall be provided. 10. When work is suspended, do not leave paint in the paint line, spray gun or spray equipment. Thoroughly flush all equipment with thinner. If the suspension is prolonged, it is recommended to mix a new batch of paint for application. 11. All equipment shall be cleaned with thinner immediately after use. Periodic flushing of spray equipment during daily work is a good practice. The flushing frequency depends on spray volume, temperature, spray time, including interruption time and other factors. 12. Residual paint and empty containers shall be disposed of in accordance with 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.
