Curing agent: none
A single-component galvanizing system composed of high-purity metallic zinc powder, volatile solvents and organic resin. The zinc content in the dry film is as high as 95%. Used for cathodic protection of offshore and onshore steel structures; can be used alone or with various other anti-corrosion coatings, suitable for long-term anti-corrosion of new or old large steel structures in marine and industrial atmospheres.

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. Blast clean to Sa 2½, surface roughness 50–75 µm. For areas with less severe corrosion, hand or power tool grinding to St 3 is acceptable, with light rust allowed to remain. Before rust removal, oil and weld spatter shall be removed and welds and sharp corners ground. If the film coated with this paint is mechanically damaged and localized rusting occurs, the area shall be spot blast cleaned to Sa 2½ or power tool cleaned to St 3 before localized repair. If this coating is to be applied over approved old hot-dip galvanized, electro-galvanized and old zinc-plus-coating surfaces, the chalking or zinc salts on the surface must be thoroughly removed before applying this product.
1. During application, ensure adequate ventilation and exhaust, keep away from sources of ignition, and wear protective equipment such as masks and gloves; maintain adequate ventilation also during curing. 2. Adjust the thinner amount according to application needs and temperature changes, stir thoroughly, then filter through a 120-mesh copper wire screen before application. 4. During application and curing, the substrate temperature must be above the dew point by 3 °C, and the surface temperature must not exceed 60 °C. The ambient temperature should be controlled at -5–35 °C, with relative humidity not exceeding 90%; indoor application is preferred when possible to better ensure appearance quality. 5. Subsequent compatible coat: a two-component epoxy MIO paint is recommended. When applying, dilute the epoxy MIO paint by half and mist spray one coat of 20–40 µm as a tie coat before normal application of the epoxy MIO paint. It must not be used directly with oil-based alkyd or polyester paints. 6. Cutting of structures coated with this paint will generate smoke and dust; take appropriate protection. 7. When work is interrupted, do not leave paint in the hose, spray gun or spray equipment. Flush all equipment thoroughly with thinner. If the interruption is too long, it is recommended to remix a new batch of paint for application. 8. All equipment shall be cleaned with thinner immediately after use. Flushing the spray equipment periodically during daily work is good practice. The cleaning frequency depends on spray volume, temperature, spraying time and interruptions. 9. Leftover paint and empty cans shall be disposed of according to local regulations.

Store sealed in a ventilated, cool and dry place, away from sources of ignition, for at least 18 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.
