All surfaces to be coated must be clean, dry and free of contaminants. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2019.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
When applying water-borne coatings, strict compliance with all cleanliness standards is essential.
Blasting: blast-clean with steel grit to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blasting and application of Interzinc 697, re-blast the surface to the specified visual standard.
Per ISO 8503-1, the surface roughness should be at least the minimum. Surface defects exposed during blasting should be ground, filled or treated by an appropriate method.
| Mixing | Interzinc 697 is supplied in two packs: liquid base (component A) and zinc powder (component B). Add the zinc powder (component B) slowly to the liquid base (component A) under mechanical agitation. Never add the liquid base to the zinc powder. Strain the paint before application and keep stirring the paint in the pot during spraying. |

Once mixed, use the paint within the specified pot life.
| Mixing ratio | 0.25 part(s) : 1 part(s) by weight |
|---|---|
| Pot life | 8 h at 20 °C (68 °F) |
| Suitable for airless spray | N/A |
| Air spray (conventional) | Recommended | Use suitable dedicated equipment. |
| Brush | Applicable — for small-area repair only | Typical thickness 50–75 µm (2.0–3.0 mils) |
| Roller application | Applicable — for small-area repair only | Typical thickness 50–75 µm (2.0–3.0 mils) |
| Thinner | Do not thin |
| Cleaner | Clean potable water, or International GTA991 |
|---|---|
| Interruption of work | Do not leave paint in the hose, spray gun or spray equipment. Flush all equipment thoroughly with clean potable water and International GTA991. Mixed paint should not be resealed. If the work interruption is long, use freshly mixed paint when resuming. |
| Cleaning | Clean equipment thoroughly immediately after use with clean water and GTA 991. Flushing spray equipment periodically during application is recommended. Cleaning frequency depends on the volume sprayed, temperature and time, including all interruptions. |
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Apply by air spray. Before application, clean the equipment with International 991 thinner or alcohol. Air spray is recommended for maximum edge coverage and film protection. Other methods such as brush and roller require multiple coats.
To ensure long-term protection, all water-borne paints require careful control of application conditions. The following basic requirements must be observed: ensure the product never freezes during the entire storage period.
During application, the minimum steel surface temperature should not be below 10 °C (50 °F), and the steel surface temperature must be at least 3 °C (5 °F) above the dew point.
During application and curing, the ideal ambient relative humidity is 50%–60%, otherwise curing and recoat intervals will be extended.
Good air flow around the object to be coated is essential. (Minimum air velocity: 0.1 m/s (4 in/s)).
The maximum continuous temperature that Interzinc 697 can withstand is 400 °C (752 °F).
Curing depends on temperature, humidity and ventilation. Normally for 75 µm dry film thickness, full cure takes 5 days at 25 °C (68 °F) and 7 days at 10 °C (50 °F).
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Interzinc 697 can only be applied over correctly prepared steel.
Normally, no other paint is applied over Interzinc 697.
