All surplus paint and empty containers must be disposed of in accordance with appropriate local regulations/laws.
Refer to the detailed Interline 994 application procedure before use.
International Paint Industrial Coatings shall be consulted to confirm the various storage chemicals for which Interline 994 is suitable. For storage of certain chemicals, heat-assisted forced curing is required. Interline 994 resists high-temperature immersion, for example in pressurised industrial water at temperatures up to 185°C (365°F). However, for service temperatures above 100°C (212°F), coating system suitability shall be approved by International. The product yellowing severely on exposure to sunlight and shall not be used on outdoor storage tanks where colour is a critical criterion.
Only for molten sulphur rail car lining applications, Interline 994 may be applied in one or two coats to a total dry film thickness of 200 ± 50 µm (8 ± 2 mils). After application, post-curing may be used to improve productivity. Refer to the Interline 994 Application Guide for detailed guidance.
Interline 994 meets the requirements of US FDA regulations and is suitable for rail cars storing and transporting liquid foodstuffs and dry grain. For details, consult International Paint Industrial Coatings.
Apply in good weather. The temperature of the surface to be coated shall be at least 3°C (5°F) above the dew point. Ensure adequate ventilation when applying Interline 994 in confined spaces.
Interline 994 shall be at a temperature above 15°C (59°F) before mixing and application. In winter, the paint shall be stored at above 15°C (59°F) for at least 48 h to reach the required minimum paint temperature.
Interline 994 does not cure adequately below 10°C (50°F). During application and for the first 48 h after application of the final coat, the steel temperature shall not fall below 10°C (50°F), and the relative humidity shall not exceed 50% at temperatures of 10-20°C (50-68°F) or 80% at temperatures above 20°C (68°F).
Drying time and recoat interval may vary with site factors such as tank geometry and ventilation rate.
Further recoat interval information;
| Third coat applied over the second coat | 10°C (50°F) 42 h | 15°C (59°F) 32 h | 25°C (77°F) 20 h | 40°C (104°F) 14 h |
| Complete coating system \"layered film\" | 24 h | 8 h | 4 h | |
Stripe coating is a basic requirement of good working practice and shall form part of any lining system. This product shall not be applied wet-on-wet over the stripe coat;
For the recoat interval between Interline 994 and the stripe coat, refer to the application guide.
Airless spray is the ideal method to achieve the maximum film thickness in a single coat. The required film thickness cannot be achieved by application methods other than airless spray.
With conventional air spray, multiple cross-coats are required to achieve the maximum film thickness. Brush and roller are recommended only for small areas.
After the final coat has cured hard, the dry film thickness of the coating system shall be measured with a suitable non-destructive magnetic thickness gauge to verify the average total thickness of the applied coats. The coating shall be free from pinholes and other misses. The cured film shall be free from ponding, sagging, runs, inclusions and other defects. All defects shall be corrected. Repaired areas shall be re-inspected and cured as specified before the final lining coat is placed in service. Refer to the International Paint Industrial Coatings Interline 994 application procedure for suitable repair procedures.
For commissioning, refer to the following minimum curing times for Interline 994
| Temporary (water)* | 10°C (50°F) 4 days | 15°C (59°F) 4 days | 25°C (77°F) 4 days | 40°C (104°F) 4 days |
| Cargo | 14 days | 11 days | 7 days | 5 days |
* For temporary water filling, all misses shall be tested and marked within 7 days. After the water is drained, the tank shall be dried.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
Interline 994 is normally applied over suitably prepared substrates. Interline 994 is suitable only for overcoating by itself.

During application and the subsequent drying period (for common drying times, see the product data sheet), provide adequate ventilation to keep solvent concentrations within safe limits and prevent fire and explosion. Forced ventilation is required in confined spaces. During application and drying, personal ventilation and respiratory protection (e.g. air-fed hood or suitable filter mask) must also be provided.
Take the necessary measures to prevent skin and eye contact with the coating (e.g. protective clothing, gloves, goggles, mask, barrier cream).
Before use, read and follow the Material Safety Data Sheet and the Health and Safety section of the application procedure for this product (for two-component coatings, those of the base and curing agent).
If welding or cutting is performed on metal substrate previously coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation.
The specific safety measures depend on the application method and working environment. If these warnings or instructions are not fully understood or cannot be strictly observed, do not use the product and consult International Paint.
