Intercryl 520 Waterborne Acrylic Coating is a waterborne coating used as a primer. It is exposed to a wide range of environments, including coastal structures, bridges, refineries, petrochemical plants and chemical plants. A low-VOC, one-component, corrosion-inhibitive waterborne acrylic coating for direct application as a primer or topcoat to suitably prepared metal, concrete or wood surfaces. Good air movement around the coated object is important [air velocity of at least 0.1 m/s (4 in/s)]. Small areas that are difficult to ventilate should be applied by brush to avoid overspray. Parameters on this page: theoretical spreading rate 8.80 m²/L, number of components one-component.

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 shall be removed in accordance with SSPC-SP1 solvent cleaning. Strict adherence to all cleanliness standards is essential when applying waterborne coatings.
Abrasive blast cleaning to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between abrasive blast cleaning and application of Intercryl 520, the surface shall be re-blast cleaned to the specified visual standard.
Surface defects exposed by abrasive blasting must be ground, filled or treated by another suitable method.
Pre-primed surfaces: Intercryl 520 may be applied over approved anti-corrosive primers. The primer surface shall be dry and free from contamination, and Intercryl 520 shall be applied within the specified recoat interval (refer to the Data Sheet of the relevant product).
Damaged areas shall be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC-SP6). Blast clean and repair the primer before applying Intercryl 520. Concrete surfaces: prior to coating application, concrete shall be cured for at least 28 days. The moisture content of the concrete shall be below 6%. All surfaces shall be clean, dry and free from curing compounds, release agents, trowelling compounds, surface hardeners, efflorescence, grease, oil, dirt, old coatings and loose or spalled concrete. All cast or precast concrete must also be treated by brush-off blast cleaning or acid etching to remove laitance.
Intercryl 520 is also suitable for GRP and concrete substrates. Contact International for details.

| Interruption of work | Flush all equipment thoroughly with International GTA991. All unused coating shall be stored in closed containers. After storage, partially filled containers may show skinning and/or increased viscosity. The coating shall be filtered before use. |
| Cleaning | Clean equipment thoroughly immediately after use with clean water and GTA 991. 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 regional regulations.
Apply by air or airless spray. Flush all equipment thoroughly with GTA991 or ethanol, then rinse with water before applying the coating. For maximum edge protection and film thickness, airless or air spray is recommended. Other application methods, such as brush or roller, may require more than one coat to achieve the specified film thickness.
To achieve long-term protective performance, application conditions for all waterborne coatings require careful control. International can supply application procedures for the relevant waterborne coatings on request.
The following basic requirements must be observed: Intercryl 520 must not be allowed to freeze at any time during storage.
During application, the steel surface temperature shall not be below 10°C and must be at least 3°C above the dew point. Relative humidity shall be below 70%, otherwise drying and recoating times will be considerably extended.
Good air movement around the object being coated is important [air velocity at least 0.1 m/s (4 in/s)].
Some small areas that are difficult to ventilate shall be applied by brush to avoid overspray.
Application at temperatures below the minimum film-forming temperature or with poor ventilation may result in poor film formation or cracking of the film. In such cases, the damaged film shall be removed promptly and the coating reapplied.
Gloss and surface evenness depend on the application method. Avoid mixing different application methods as far as possible.
For an ideal appearance with brush and roller application, two coats of Intercryl 520 may be required for certain colours to achieve uniform coverage.
Intercryl 520 must be fully cured before exposure to standing water; otherwise loss of adhesion will occur.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Intercryl 520 is designed for use as a primer or topcoat. Intercryl 520 can be applied over a range of primers: waterborne coatings: Intergard 270, InterH2O 401, InterH2O 280; solvent-borne coatings:
| Intercure 200 | Interseal 670HS |
|---|---|
| Intercure 420 | Interzinc 12* |
| Intergard 251 | Interzinc 22* |
| Intergard 269 | Interzinc 42 |
| Intergard 475HS | Interzinc 52 |
| Interprime 198 | Interzinc 315* may require a sealer coat. The following topcoats are recommended for use with Intercryl 520: Intercryl 520, Intercryl 530. For other suitable primers/topcoats, consult International Paint Industrial Coatings. |
