Intergard 7500 High-solids Pure Epoxy Universal Primer is an epoxy coating used as a primer. Very suitable as a universal primer for underwater hulls, freeboard, exterior superstructures, decks, oil tanks and ballast tanks of offshore platforms and floating production and storage facilities. A two-component high-solids, abrasion-resistant, aluminium-flake pure epoxy primer providing long-term corrosion protection. Although the low-molecular-weight reactive additive becomes part of the film on curing under normal ambient conditions, EPA Method 24 analysis shows that it also affects the VOC value. Parameters on this page: dry film thickness 100–200 µm (4–8 mil), theoretical spreading rate 6.40 m²/L, number of components two.

All surfaces to be coated must be clean and free of contamination. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Blast cleaning: abrasive blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. If oxidation occurs between blasting and application of Intergard 7500, the surface shall be re-blasted to the specified visual standard.
Surface defects exposed during abrasive blasting must be ground, filled or treated by a suitable method.
Peeled, damaged and similar areas shall be prepared to the specified standard (e.g. Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 blast, or SSPC-SP11 manual/power tool), and primed before applying Intergard 7500.
| Mixing | This product is supplied in two containers as one unit. Always mix the entire unit in the specified ratio. Once mixed, use within the specified pot life. |

| Suitable for airless spray | Recommended: nozzle diameter 0.63–0.79 mm (25–31 mil); total paint pressure at the nozzle not less than 211 kg/cm² (3000 psi) |
|---|---|
| Air Spray | Not recommended (with pressure pot) |

| Roller application | Recommended — for small areas only | Several coats may be required to achieve the specified film thickness. |
| Thinner | International GTA220. | Thinning ratio shall not exceed 5% by weight. Do not thin beyond the local |
environmental regulation limits
| Cleaner | Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. Once mixed, paint should not be resealed; if work is interrupted for too long, mix a fresh batch for application. |
| Cleaning | All equipment should be cleaned immediately after use with International thinner. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature, spraying time, including interruptions, and other factors. |
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Airless spray is the ideal method to achieve the maximum film thickness in one coat. Application methods other than airless spray are unlikely to achieve the required film thickness.
Low or high temperatures may require specific application techniques to achieve the maximum film thickness.
When applying Intergard 7500 by brush or roller, multiple coats are necessary to achieve the specified total system dry film thickness.
Intergard 7500 can be applied on substrates at temperatures down to −15 °C. Before applying at temperatures below −5 °C, consult the local International Paint representative for the detailed application procedure.

| Interthane 990 | 21 h | 8 days | 10 h | 7 days | 3 h | 5 days | 2 h | 3 days |
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
When applying Intergard 7500 in confined spaces, ensure adequate ventilation.
As with all epoxy coatings, Intergard 7500 chalks and fades on exposure to the atmosphere. This does not affect anti-corrosion performance.
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.
Intergard 7500 is normally applied directly to metal surfaces. The following topcoats are recommended for use with Intergard 7500: Intergard 7500, Interthane 990, Interthane 990E.
