*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 air extraction, keep away from ignition sources, and wear protective equipment such as masks and gloves; maintain adequate ventilation during curing. 2. Stir the paint uniformly first, add the hardener in the specified ratio and stir uniformly, then adjust the thinner amount according to application requirements and temperature variation and stir thoroughly. As the mixing ratio is high, weighing equipment shall be used when small quantities of paint are prepared; volumetric marking cannot proportion the paint accurately by volume. 3. The coating cannot achieve ideal physical and mechanical properties before heat-induced secondary curing; handle with extra care during transport to avoid coating damage. Under prolonged high-temperature exposure, the film may show slight colour change and yellowing. 4. Excessive film thickness or too short a recoat interval seriously affects drying and curing, heat resistance, recoating performance and handling time. At a design maximum temperature of 400°C the maximum film thickness is 160 µm, at 450°C the maximum film thickness is 90 µm, and where the maximum temperature exceeds 540°C the maximum coating film thickness shall not exceed 60 µm. 5. After prolonged exposure of the coating, ensure the existing film surface is free of contaminants before recoating, and abrade the surface before applying subsequent coats. 6. When applied over inorganic zinc silicate primer, ensure the primer has fully cured (MEK test at least grade 4). 7. Thick films of the product must be fully dried and cured for at least 7 days before service; otherwise an incompletely cured coating will not achieve good heat 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; relative humidity shall not exceed 85%. Avoid application on surfaces above 40°C, which may cause blistering and poor flow. 9. Cutting structures coated with this paint generates fume and dust; adequate protection shall be provided. 10. When work is paused, do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. If the pause is prolonged, prepare a fresh mixed batch of paint for application. 11. Clean all equipment with thinner immediately after use. Flushing spray equipment at regular intervals during daily work is good practice. Cleaning frequency depends on spray volume, temperature, spraying time and interruption time. 12. Surplus paint and empty containers shall be disposed of in accordance with relevant regional 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.
