| Cleaning | Clean all equipment with International GTA853 immediately after use. Periodic flushing of spray equipment during application is recommended. Cleaning frequency depends on spray volume, temperature and time, including all interruption periods. |
Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
| Refer before use to the detailed content of | the Recommended Procedure for Tank Lining Coatings. |
|---|---|
| Interline | 961 is normally applied as a two-coat system, each coat 125 µm (5 mils) thick, so that the total dry film |
| thickness can reach | 250 µm (10 mils). The exact total dry film thickness depends on the requirements of the end use. For specific recommendations on the application of tank lining coatings, consult International Paint Industrial Protective Coatings. |
Airless spray is the ideal means of achieving the maximum film thickness in a single coat. Without airless spray, obtaining the required film thickness is unlikely. Conventional spray may require multiple cross-spray passes to achieve the maximum film thickness. Other methods (brush, roller) may require more than one coat and are recommended only for small areas or initial precoating.
Areas with severe rust staining shall be precoated by brush to wet the surface effectively.
Surface temperature must be at least 3°C (5°F) above dew point.
| Do not apply if the steel temperature is below | 10°C (50°F). |
|---|
Exposure to excessively low temperature or high humidity during or immediately after application may result in incomplete curing and surface contamination, reducing intercoat adhesion.
| Application in confined or limited spaces | Adequate air circulation shall be maintained for Interline 961. |
|---|---|
| Interline | Excessive thickness of 961 will cause cracking. The film thickness of a single coat must be within the recommended limit. The total dry film thickness of multiple coats shall not exceed 350 µm. |
Maximum chemical resistance is achieved only after the film is fully cured. Factors affecting curing include temperature, humidity and film thickness.
Under normal conditions, a film of 250 µm (10 mils) dry film thickness cures fully in 7-10 days at 25°C (77F), at which point it has the desired chemical resistance. Curing time is proportional to temperature: higher temperature, shorter time; lower temperature, longer time.
Curing time varies with dry film thickness and the conditions during application and curing.
After the final coat has hardened, the dry film thickness of the complete coating system shall be measured with a suitable non-destructive thickness gauge to determine the average total thickness applied. The coating shall be free from pinholes and other misses. The cured film shall be essentially free from sags, runs, inclusions and other defects. All defects shall be remedied. Repaired areas shall be retested and cured in accordance with the above steps before being placed in service. For correct repair procedures, refer to the tank lining procedure of International Paint Industrial Protective Coatings.
| If the cargo temperature exceeds | 60°C (140°F), the tank must be insulated to prevent blistering (the 'cold wall' effect) caused by the temperature difference between the coating and the substrate, which may lead to premature coating failure. |
