A two-component epoxy zinc-rich primer complying with the composition and performance requirements of HG/T 3668.
Highly suitable for cathodic protection of steel structures, vessels, equipment and pipelines whose surfaces are exposed to mild to severe industrial environments. Because of simple application, wide compatibility and fast drying and overcoating, it is also highly suitable for touch-up and maintenance work.

All surfaces of the steel substrate to be coated must be clean, dry and free of contamination. Before painting, all surfaces must be assessed and prepared in accordance with GB 18839-2002.
Where required, remove weld spatter and grind welds and sharp edges smooth.
Blast clean to at least Sa 2 (GB 8923-1:1998); a cleaner surface, such as Sa 2.5 (GB 8923-1:1998), improves primer and coating performance. The blasted surface should be angular and sharp rather than “flat”, with surface roughness of 38–62 µm. The surface to be coated must be free of dust.
Previously painted surfaces: Interdur 8810 cannot be applied directly over existing coatings. All existing coatings must be removed by blasting to at least Sa 2 (GB 8923-1:1998).
| Mixing | The material is supplied in two containers. Always mix the whole container as a unit. The zinc metal is pre-mixed and stored in Part A. Slowly add Part B while mixing slowly until completely uniform. At 60 °F (16 °C), allow to stand for 15 minutes before use; for every 10 °F (6 °C) drop in temperature, increase the standing time by 10 minutes. |
|---|---|
| Mixing ratio | 9 parts : 1 part (by volume) |
| Pot life | 5°C (41°F) | 15°C (59°F) | 25°C (77°F) |
| 7 h | 6 h |
| Suitable for airless spray | Recommended nozzle tip 0.63–0.63 mm (25–25 thousandths of an inch); total paint pressure at the nozzle not less than 207 kg/cm² (2944 lb/in²) |
|---|---|
| Air Spray | Suitable: use a nozzle of 1.78 mm (0.070 '') or larger, professional-grade conventional |
| (with pressure pot) | spray gun, forming a spray. |
| Brush | Suitable |
| Roller application | Suitable |
| Thinner | International GTA220. |
| Cleaner | International GTA220S. Select a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
| Interruption of work | Do not leave material in hoses, guns or spray equipment. Flush all equipment thoroughly with International GTA220S. Once mixed, paint should not be resealed; if work is interrupted for too long, mix a fresh batch for application. |
| Cleaning | Clean all equipment immediately after use with International GTA220S. 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 local regulations.
