Intersheen 7579 Modified Acrylic Topcoat is an acrylic coating used as a topcoat. For atmospheric environments in power and downstream oil and gas projects. A one-component, fast-drying modified acrylic topcoat. Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, EPA Method 24 analysis shows that it also affects the VOC value. Parameters on this page: volume solids 54% ± 2%; dry film thickness 50–75 µm (2–3 mils); theoretical spreading rate 10.80 m²/L. Comparable products from the same brand: Interdur 8862 Acrylic Polysiloxane Topcoat, Interfine 629 High-performance Topcoat, Interfine 629HS.

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.
Primed surfaces: Intersheen 7579 should always be applied over a recommended anti-corrosive primer. The primer surface must be dry and free of contaminants, and Intersheen 7579 must be applied within the specified recoat interval (refer to the relevant product data sheet).
Cracked or damaged areas should be prepared to the standard specified (e.g. Sa 2½ (ISO 8501-1:2007), SSPC SP6 or SSPC SP11), and the primer repaired before applying Intersheen 7579.
| Mixing | This product is a single-component coating; stir thoroughly with a power mixer before each use |
|---|
| Suitable for airless spray | Recommended | Nozzle tip range 0.38–0.53 mm (15–21 thousandths of an inch) |
| Brush | Recommended — for small areas only | Several coats may be required to achieve the specified film thickness. |
| Roller application | Recommended — for small areas only | Several coats may be required to achieve the specified film thickness. |
| Thinner | Normally not required. If necessary, use International Paint GTA007 thinner. |
|---|---|
| Cleaner | International GTA007 |
| Interruption of work | Flush all equipment thoroughly with International GTA007. All unused paint shall be stored in tightly closed containers. Partly filled containers may develop skinning and/or increased viscosity after a period of storage. |
| 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 delays, and other factors. |
All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
Apply in good weather. The surface temperature must be at least 3 °C (5 °F) above the dew point. During application and curing, ensure adequate ventilation.
Intersheen 7579 should always be protected from ponding or running water, condensation/high humidity and chemical attack.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
Gloss and surface evenness depend on the application method. Avoid mixing different application methods as far as possible.
When applying Intersheen 7579 by brush or roller, take care to avoid 'lifting' recently applied one-component coatings.
Some colours may require more than one coat to achieve full hiding and the intended appearance.
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.
The following primers are approved for use with Intersheen 7579: Interprime 198. For other suitable primers, consult International Industrial Coatings.
