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 8504:2000.
Blast cleaning: the surface preparation requirement for Chartek 1620CSP application is: blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. A sharp angular surface roughness of 50–75 µm (2–3 mils) is recommended.
Primer: for protection against cryogenic liquid spillage, it is important that the whole coating system has good thermal insulation and fire protection performance. The preferred primer should be epoxy or epoxy zinc powder type (e.g. Intergard 269, Intershield 300 or Interzinc 52/Intergard 269). International Paint publishes a list of qualified primers; primer thickness information should be checked against that list.
Damaged/repair areas: all areas to be repaired are preferably blasted to Sa 2.5 (ISO 8501-1:2007) or SSPC-SP10. However, areas smaller than 1 m² may be power tool cleaned to SSPC-SP11, with a clean surface having roughness. A roughness of 50–75 µm must be achieved. The recommended primer can then be applied before Chartek 1620CSP.
| Mixing | If using approved modified single-component airless spray equipment or trowel application for Chartek 1620CSP, first thoroughly mix one kit of Chartek 1620CSP. Each component must be stored at 20–30 °C (68–86 °F) for 24 hours, and thoroughly stirred with a power tool before mixing. |
|---|---|
| Mixing ratio | Always mix the whole unit of coating (for manual application methods, see the Chartek application specification manual) |
| Pot life | 15°C (59°F) | 25°C (77°F) |
| 90 min | 50 min |
The above data applies to trowel application. The pot life does not apply to dual-pump airless spray application, because the product is only mixed in a static mixer near the spray gun. For approved modified single-component airless spray equipment, the pot life will be correspondingly shortened according to the above data. Refer to the Chartek application guide.
| Plural-component airless spray | Recommended and preferred equipment: AkzoNobel-approved heated dual pump equipment |
|---|---|
| Suitable for airless spray | Recommended - for small areas only: use International Paint-approved modified single-component airless spray equipment, compression ratio at least 68:1, (see the Chartek application guide for more details), normally thinned up to 5%. |
| Trowel application | Applicable — for small-area repair only | Thinning ratio maximum 5% by weight |
| Thinner | International GTA123 | For premixed application and trowel application only — refer to the Chartek 1620CSP 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: more than 3 °C (5 °F) above the dew point of the surrounding air. General: the surface must be clean, dry and free of contaminants, and can then be coated. Chartek 1620CSP should be applied by spray to ensure complete wetting of the substrate. If more than spray is used, the first coat should be thoroughly trowelled and rolled to achieve this. The better self-overcoating time for Chartek 1620CSP is after the minimum self-overcoating interval is reached, or before the coating has any chance of being contaminated.
When applying the recommended Chartek topcoat, the following overcoating intervals must be observed:
Minimum maximum
| 10°C (50°F) | 24 h; 7 days |
|---|---|
| 25°C (77°F) | 18 hours 7 days |
| 40°C (104°F) | 6 hours 4 days mesh installation: if reinforcement mesh is needed, International Paint's HK-1 or HK-2 carbon fibre mesh should be installed according to the fire protection design with reference to the Chartek application manual. Special fire scenarios, e.g. fires containing an expected jet fire period, may require specific mesh and film thickness. Detailed requirements must be elaborated according to the specific project, and approved by certification bodies such as LR or DNV. |
After mesh application, continue spraying Chartek 1620CSP to the required film thickness. Equipment must be equipment approved by International Paint Protective Coatings, used according to the detailed provisions in the Chartek application manual or the guidance of International Paint Protective Coatings field technical service engineers.
Applicator certification: only companies certified by AkzoNobel as qualified applicators may apply Chartek 1620CSP. These companies must be documented before application. Chartek 1620CSP application shall be carried out by the application company using qualified personnel trained in the correct application procedures. At minimum, site supervisors and QA/QC personnel shall hold individual qualifications and have attended the AkzoNobel Chartek applicator training course. This is the 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.
Maximum surface operating temperature: when the temperature is between 80–120 °C (176–248 °F), a suitable thermal insulation layer, e.g. Intertherm 7050, should be used between the substrate and Chartek 1620CSP.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Chartek 1620CSP is normally applied over substrates with a suitable primer. Contact International Paint to confirm the correctness of the primer selection.
Chartek 1620CSP should be topcoated to meet the owner's colour scheme and appearance requirements.
Suitable topcoats are: Interfine 629HS; Interthane 990; Interzone 954
