Basic physical and chemical data

Application parameters

Application Methods

*For low-temperature application and where fast hard drying is required, use a fast thinner.

Theoretical Spreading Rate

Application data (typical 80 µm dry film, 65% relative humidity):

*Normally this product requires no recoating

All surfaces to be coated shall be clean, dry and free from contaminants. Before coating, all surfaces shall be assessed and treated in accordance with ISO 8504:2000.

Surface Preparation

Blast to Sa 2½ with surface roughness 50–80 µm. Before rust removal, remove oil, grease and welding spatter, and grind welds and sharp corners. Film surfaces coated with this coating, where mechanically damaged and locally rusted, shall be locally blast cleaned to Sa 2½ or power-tool cleaned to St3 before local repair of the primer.

Precautions

1. During application, ensure ventilation and exhaust, keep away from sources of ignition, and wear protective equipment such as masks and gloves; adequate ventilation shall also be maintained during curing. 2. Slowly add the zinc dust component while stirring the liquid component, power-stir until fully mixed, adjust the thinner quantity according to application needs and temperature changes, stir well, strain through a 120-mesh sieve before use, and keep stirring during use. If the zinc dust is poured directly into the liquid component, or thinner is added before mixing, the paint is difficult to mix uniformly, and defects such as gun blockage and uneven film tend to occur. 3. The maximum applied film thickness permitted for this product is 150 µm; over-thick application may cause cracking, affecting the curing process and adhesion. During application, pay attention to edge treatment and over-thick application, to avoid cracking and slow curing. 4. This product is suitable only for application over blast-cleaned steel surfaces and inorganic zinc silicate coating surfaces; it must not be applied over other types of coating. Substrate surfaces with too-low roughness or smooth coated surfaces cannot obtain good adhesion and may even shed. 5. During application and curing, the substrate temperature must be above 5 °C and at least 3 °C above the dew point, and relative humidity shall not exceed 85%. Temperature and relative humidity shall be measured on the substrate near the working area. Maintain good ventilation at the application site, with relative humidity not below 60%. If the humidity is below 60% during actual application, water spraying is required; when installing bolted/riveted members, assess the degree of cure per ASTM D4752, achieving at least Grade 4. 6. This product is not recommended for other applications. 7. Cutting structures coated with this coating produces fumes; take appropriate protection. 8. When work is interrupted, do not leave coating in the paint line, spray gun or spray equipment. Flush all equipment thoroughly with thinner. If the interruption is too long, it is recommended to mix a fresh batch of paint for application. 9. Clean all equipment with thinner immediately after use. Periodically flushing spray equipment during the working day is good practice. The flushing frequency depends on the spray quantity, temperature and spray duration, including interruptions. 10. Dispose of leftover paint and empty cans in accordance with the relevant local regulations.

Packaging

Storage

Keep sealed in a ventilated, cool, dry place away from sources of ignition. Minimum 9 months.

Safety Precautions

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.
