Surface preparation and application should follow the recommendations in the AkzoNobel Chartek 7E application specification manual.
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.
Blasting: Chartek 7E is normally applied to surfaces blast-cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10 and overcoated with a suitable primer.
The selected primer or primer system must be on the AkzoNobel qualified primer list. The preferred primer is an epoxy type specified at no more than 75 µm (3 mils). A two-coat primer system, such as epoxy zinc-rich and tie coat, may also be used; the combined specified thickness should not exceed 110 µm (4.5 mils).
| Mixing | For trowel application, the individual components should be stored at 35 °C (95 °F) and thoroughly power-stirred before mixing. |
|---|---|
| Mixing ratio | Weight ratio 2.74:1, refer to the Chartek 7E application specification manual |
| Pot life | 10°C (50°F) | 20°C (68°F) | 40°C (104°F) |
| 40 min | 35 min | 25 min |
The pot life value refers to undiluted trowel application performance with the material heated to 35 °C (95 °F) before mixing. If the material is not pre-heated, the pot life is extended but mixing is more difficult.
The pot life does not apply to dual-pump airless spray application, since the product is mixed only in the static mixer near the gun. Refer to the product application manual.
| Plural-component airless spray | Recommended and preferred equipment | Heated two-pump equipment approved by AkzoNobel. No thinner required. |
| Suitable for airless spray | Suitable | Modified airless spray equipment approved by AkzoNobel is recommended, with a minimum |
ratio of 68:1. Normally thinned with up to 5% solvent by volume.
| Trowel application | Suitable | Refer to the Chartek 7E application specification manual |
| Thinner | International GTA123 | For premixed application and trowel application only — refer to the Chartek 7E application specification manual |
| Cleaner | International GTA007 |
|---|---|
| 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 delays, and other factors. |
|---|
All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
Throughout application, the following conditions must be present (or created):
| Minimum air temperature | 10°C (50°F) |
|---|---|
| Maximum humidity | 85% |
| Surface temperature | At least 3 °C (5 °F) above the dew point of the surrounding air. |
| General | Immediately before coating, the surface must be clean, dry and uncontaminated. Chartek 7E should be applied by spray to ensure complete substrate wetting. If spraying alone is not used, the first coat should be thoroughly trowelled and rollered to achieve this. The best self-recoat time for Chartek 7E is after the minimum self-recoat interval, or before the coating has any chance of being contaminated. |
If Chartek 7E is to be overcoated with a recommended topcoat, use the following recoat intervals:
Minimum, maximum*
| 10°C (50°F) | 24 h; 7 days |
|---|---|
| 20°C (68°F) | 18 h; 7 days |
| 40°C (104°F) | 6 h, 4 days (*for Interthane 990, the maximum recoat interval is 6 months). Mesh installation: some areas require no reinforcement mesh. If reinforcement mesh is required, install AkzoNobel HK-1 or HK-2 carbon fibre mesh per the specific fire design, following the detailed instructions in the Chartek 7E application specification manual. For mesh requirements, seek AkzoNobel's specific advice. |
After mesh application, continue spraying Chartek 7E to the required film thickness. Only equipment approved by the AkzoNobel Chartek 7E application specification manual and technical service representative may be used.
Applicator certification: only companies holding qualified contractor certification issued by AkzoNobel may apply Chartek 7E. These companies must document this before application. Chartek 7E must be applied by the contractor using qualified staff trained in the correct application procedure. At minimum, site supervisors and QA/QC personnel must hold individual qualifications and have attended the AkzoNobel Chartek applicator training course. This is a minimum requirement and must be documented in writing before application.
Inspection and quality assurance. This is the applicator's responsibility and must at least follow the procedures specified in the AkzoNobel Chartek QC manual. Technical service. Available from AkzoNobel and should be coordinated to be present at start of work. The applicator is responsible for ensuring AkzoNobel is notified of the start date.
Other surface preparation. For some project-specific environments, AkzoNobel has developed procedures for wet blasting, ultra-high-pressure water jetting and power tool preparation.
Maximum surface operating temperature: when the temperature is between 80–120 °C (176–248 °F), use a suitable thermal barrier between the substrate and Chartek 7E, e.g. Intertherm 7050.
Note: application density values are typical and for guidance only. Refer to the Chartek 7E application specification manual.
Chartek 7E is designed for application to substrates that are correctly prepared and overcoated with a suitable primer. The following primers can be used with Chartek 7E:
| Intergard 269 | Intershield 4000USP |
|---|---|
| Intergard 7500 | Interzinc 52/Intergard 269, Intershield 300. Chartek 7E is normally overcoated with a topcoat to meet the owner's colour scheme and topcoat requirements. AkzoNobel Protective Coatings recommends a topcoat in all exterior service environments. |
The following topcoats are recommended for use with Chartek 7E: Interfine 2080*, Interthane 990, Interzone 954. *Available by region.
