All surfaces to be coated must be clean, dry and free from contamination. Before coating, all surfaces must be assessed and treated in accordance with ISO 8504:2000. Blast clean to Sa 2½, surface roughness 40~75 µm. Before rust removal, remove all oil, grease and weld spatter from the surface and dress welds and sharp corners. On areas of the coated film that have suffered mechanical damage with local rusting, blast clean locally to Sa 2½ or prepare to St 3 by power tool before local repair. For concrete protection, the concrete must meet curing requirements, with moisture content and surface condition complying with relevant regulations. Blast clean to remove laitance and loose material, forming a sound, uniform surface; mechanical or acid etching treatment may also be used. Seal the surface with a suitable sealer according to the relevant coating requirements.
1. During application, ensure ventilation and exhaust, keep away from sources of ignition, and wear protective equipment such as masks and gloves; adequate ventilation should also be maintained during curing. 2. Before mixing Components A and B, stir the base thoroughly with a power tool, then add the curing agent and mix thoroughly; adjust the amount of thinner according to application needs and temperature changes, stir thoroughly and induce for 10~15 min before application. 3. The product can be used as a primer for galvanised steel or stainless steel; abrading or light blasting of these substrate surfaces provides better adhesion. 4. When used as a protective primer for concrete, the product is normally used with a concrete-specific sealer to seal the concrete; ensure that the sealer is hard dry before applying subsequent coats. 5. If applying the product over an old zinc-rich primer film, the chalking or zinc salts on the zinc-rich coating must be thoroughly removed. 6. The recommended single-coat thickness of the product should not exceed 200 µm. If the coating chalks after long-term exposure, wash with high-pressure water or abrade the surface before applying the subsequent coat. 7. When used as an internal anticorrosive layer for tanks and concrete pools, it is normally used with glass fibre cloth to form an FRP lining; the application procedure in standard SY0326 may be followed. Pay particular attention to applying the cloth before the film is touch dry, otherwise the adhesion of the glass fibre cloth will be affected; after applying the cloth, allow it to dry for more than 12 h before applying the next coat; repeat the above process to reduce the residual solvent content in the film and improve the strength of the lining. 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 must not exceed 85%. Temperature and relative humidity must be measured on the substrate near the work area. 9. Cutting structures coated with this product produces smoke and dust; take appropriate protection. 10. When work is interrupted, do not leave the coating in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. If the interruption is too long, mix a fresh batch of paint for application. 11. All equipment should be cleaned with thinner immediately after use. Periodic flushing of spray equipment during the working day is good practice. The cleaning frequency depends on spray volume, temperature, spray time and factors including interruptions. 12. Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.

Keep sealed in a ventilated, cool, dry place away from sources of ignition. Minimum 12 months.
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.
