The performance of this product depends on the degree of surface preparation. All surfaces to be coated must be clean, dry and free of contamination. Before painting, all surfaces must be assessed in accordance with ISO 8504:2000
| assessed and prepared in accordance with the standard. | Accumulated dirt and soluble salts must be removed. Dirt is generally brushed off with a dry bristle brush. Soluble salts should be washed off with fresh water. |
|---|
Abrasive blast cleaning to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between abrasive blast cleaning and application of Interzone 3507, 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.
Recommended angular surface profile of 50–75 µm (2–3 mils).
| 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. |

| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. |
Mixed paint should not be resealed. If work is interrupted for too long, mix a fresh batch of paint for application.
| Cleaning | Clean all equipment immediately after use with International thinner. 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.
When Interzone 3507 is applied by brush or roller, multiple coats are necessary to achieve the specified total system dry film thickness.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
In exceptional cases where recoating is required but the film has cured under conditions of low temperature and high humidity, ensure the absence of amine salts before applying the subsequent coat.
Condensation during or immediately after application may cause loss of gloss on the surface and film defects.
Premature exposure to standing water may cause colour change, especially for dark colours.
As with all epoxy coatings, Interzone 3507 will chalk and fade when exposed to the atmosphere. This phenomenon does not affect anticorrosive performance.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Interzone 3507 is mainly applied to steel prepared by dry abrasive blast cleaning.
The following primers may be used in a coating system with Interzone 3507: Interzinc 52. The following topcoats are recommended for use with Interzone 3507: Intergard 740, Interthane 990, Interthane 990E. For other suitable primers/topcoats, consult International Paint.
