*The maximum overcoating interval depends on the coating exposure environment and use. For application at 0–10 °C, the use of XH7323-11K hardener is recommended.
All surfaces to be coated shall be clean, dry and free of contaminants. Before coating, all surfaces shall be assessed and treated in accordance with ISO 8504:2000. Where the film of this coating is mechanically damaged or shows local rusting, blast clean the affected area to Sa 2½ or power tool clean to St 3 before local repair. When applying over other old coatings, remove chalk, zinc salts, grease and other contaminants from the surface by suitable methods. When applying over an inorganic zinc silicate primer or metal-sprayed surface, use an approved tie coat or transition coat.
1. During application, ensure good ventilation and exhaust, keep away from ignition sources, and wear a mask, gloves and other protective equipment; adequate ventilation shall also be maintained during curing. 2. When mixing, first stir the base thoroughly, then add the curing agent in the specified ratio and mix uniformly; adjust the thinner amount according to application requirements and temperature changes, and mix and induce thoroughly. 3. When applied over inorganic zinc silicate coatings, a tie-coat shall be used for sealing; the product shall be applied only after the tie-coat is hard dry, otherwise the effectiveness of sealing pinholes will be reduced. 4. Excessive thinning will reduce sag resistance and slow curing. 5. Over-thick application will seriously affect drying, curing, overcoating performance and handling time. For better coating performance, when the film thickness exceeds 200 µm, apply in multiple coats to improve film density. Avoid over-thick application in a single pass on edges, corners, welds and similar areas; where these areas have been over-applied, the overcoating interval of subsequent coats shall be extended to allow solvent release, otherwise the coating may crack in service. 6. If the coating chalks after long-term exposure, wash with high-pressure water or abrade the surface before applying the next coat. 7. With roller application, high film thickness and a good continuous film cannot be obtained in a single pass; multiple coats are required. 8. During application and curing, the substrate temperature shall be above 5 °C and at least 3 °C above the dew point, and the relative humidity shall not exceed 85%. 9. Cutting structures coated with this coating produces fumes; appropriate protection shall be taken. 10. When work is interrupted, do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. If work is interrupted for too long, remix a fresh batch of paint before resuming. 11. All equipment shall be cleaned with thinner immediately after use. Periodically flushing spray equipment during the daily work is good practice. The frequency of cleaning depends on the quantity sprayed, temperature, spraying time and interruptions. 12. Remaining paint and empty cans 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.
