Interdur 8817 Epoxy Zinc-rich Primer is a zinc-rich primer of the epoxy coating system. Interdur 8817 is a primer used as part of an anticorrosive coating system on new structures and provides additional protection in various severe corrosive environments, including: onshore coastal structures, petrochemical plant, paper mills, bridges and power plants. A two-component epoxy zinc-rich primer conforming to Chinese chemical industry standard HG/T 3668. Over-application of Interdur 8817 extends the minimum recoat time and handling time and adversely affects long-term recoatability. Parameters on this page: volume solids 67 ± 2%, dry film thickness 60–125 µm (2.4–5 mil), theoretical spreading rate 8.93 m²/L.

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.
Abrasive blast cleaning: blast clean at least to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blast cleaning and application of Interdur 8817, the surface shall be blast cleaned again to the specified visual standard. Surface defects exposed during blast cleaning shall be ground, filled or treated by other suitable methods.
Recommended surface profile 40–75 µm (1.6–3.0 mil).
| Mixing | This product is supplied in two containers forming one unit. Mix the two components in the specified ratio in one operation. Once mixed, use within the specified pot life. |

(1) Stir the base (Component A) with a power mixer.
(2) Mix all of the curing agent (Component B) with the base (Component A) and stir thoroughly with a power mixer.

| Air Spray | Recommended | Spray gun | DeVilbiss MBC or JGA |
| Air nozzle | 704 or 765 | ||
| (with pressure pot) | Nozzle | E | |
| Brush | Suitable | For small areas only | |
| Roller application | Not recommended | ||
| Thinner | International GTA220 | Do not exceed the thinning limits of local environmental regulations | |
| Cleaner | International GTA220S | Select a cleaner complying with local regulations. For specific usage recommendations, consult the local |
representative.
| 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.
For good anticorrosive performance, a minimum film thickness of 60 µm is important. The film thickness of the product shall match the surface profile of the substrate; on a high-profile substrate, a low film thickness shall not be applied.
Care shall be taken to avoid applying a dry film thickness above 150 µm (6 mil). Avoid over-thick application; if the film is too thick, cracking may result from cohesive failure. Dry spray shall also be avoided, otherwise pinholes will appear.
Over-application of Interdur 8817 extends the minimum recoat time and handling time and adversely affects long-term recoatability.
Where Interdur 8817 is allowed to weather before topcoat application, ensure that all zinc salts are removed before painting and that only recommended materials are used for topcoat application.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
Interdur 8817 is not recommended for underwater service. Consult International Paint for details on this.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
Recommended topcoats include: Interdur 8840, Interdur 8841, Interdur 8860, Intergard 475HS. For other suitable topcoats, consult International Paint Protective Coatings.
