Intersheen 579 Sealer is an acrylic paint, used as a topcoat. Used as the sealer for a single-component acrylic intumescent coating system. A single-component, fast-drying modified acrylic topcoat. When Intersheen 579 is used as the sealer for intumescent fire protection coatings, the whole system is not suitable for exposure to environments with corrosivity above C3 (as defined in ISO 12944-2). Parameters on this page: volume solids 35% ± 3%, dry film thickness 40–50 µm (1.6–2 mils), theoretical spreading rate 8.80 m²/L. Comparable products of the same brand: Interdur 8862 Acrylic Polysiloxane Topcoat, Interfine 629 High-performance Topcoat, Interfine 629HS.

Before applying Intersheen 579 over intumescent coatings, check the dry film thickness of the intumescent coating; the surface shall be clean, dry and free of any loose material or surface contaminants. For the ideal overcoating interval, refer to the Interchar application manual for more information.
Shop-primed steel: Intersheen 579 can be applied over approved anti-corrosive primers. The primer surface shall be dry and free of any contaminants; Intersheen 579 must be applied within the specified overcoating interval (see the relevant product data sheet).
Areas of cracking, damage, etc. shall be treated to the specified standard (e.g. abrasive blast cleaning to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10, or power tool cleaning to SSPC-SP11), and the primer repaired before applying Intersheen 579.
| Mixing | This product is a single-component coating; stir thoroughly with a power mixer before each use |
|---|---|
| Suitable for airless spray | Recommended: nozzle diameter 0.38–0.53 mm (15–21 thousandths of an inch); total paint pressure at the nozzle not less than 176 kg/cm² (2503 psi) |
| Air spray (conventional) | Not recommended |
| 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 | International GTA007 | Do not exceed the thinning limits of local environmental regulations |
| 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 GTA 007. 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.
The surface temperature to be coated shall be at least 3 °C (5 °F) above the dew point. Ensure adequate ventilation during application and curing.
Intersheen 579 can also be used as a decorative topcoat, applied over single-component primers and intermediate coats.
Intersheen 579 shall always be protected from ponded or running water, condensation/high humidity and chemical attack. When Intersheen 579 is used as the sealer for intumescent fire protection coatings, the whole system is not suitable for exposure to environments with corrosivity above C3 (as defined in ISO 12944-2).
Refer to the acrylic intumescent fire protection coating application manual for more information.
Gloss and surface smoothness depend on the application method. Mixing different application methods shall be avoided as far as possible. Condensation on the surface during or after application will result in a matt finish and an inferior film.
Intersheen 579 is certified to Spanish UNE 23.727-90 (reaction to fire) and UNE 23721-90 (radiation).
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
