A two-component, solvent-free, chemically resistant epoxy phenolic heavy-duty lining coating.
Interline 984 can be used as a lining coating for the protection of ferrous and non-ferrous substrates (including concrete). It can be used as a single coat or multiple coats, or sprayed together with fibre reinforcement, or applied by hand together with a glass fibre reinforcement system.
Interline 984 is designed as a lining coating for oil and gas downstream, with a long overcoating time, which assists project scheduling related to lined storage tanks.
Interline 984 is suitable for crude oil immersion environments and can withstand a maximum temperature of 90 °C (194 °F). Interline 984 meets the EI1530 standard (Joint Industry Standard). This is a quality assurance requirement for the manufacture, storage and transport of aviation fuel to airports.
Interline 984 is suitable for pipeline lining applications.
Resistant to various renewable/bio-based feedstocks and refined products (oils), including animal/vegetable oils and fats, biodiesel, ethanol and other substances.

| Typical thickness | When used as an unreinforced lining system for internal surfaces or as a laminate gelcoat at 300–600 µm, the tank bottom may be applied in a single coat at 400–1000 µm (16–40 mil). |
When used as a glass fibre laminate, 1250–1400 µm thickness depends on the application method and system.

All surfaces to be coated must be clean, dry and free of contaminants. Before painting, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Where required, remove weld spatter and grind welds and sharp edges smooth.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Abrasive blasting: the product shall be applied only to surfaces abrasive-blast-cleaned to Sa2½ (ISO 8501-1:2007) or SSPC SP10. A sharp, angular surface profile of 75–100 µm (3–4 mil) is recommended.
Interline 984 must be applied before oxidation of the steel occurs. If oxidation has occurred, the entire oxidized area shall be re-blasted to the specified standard. Surface defects exposed during blasting shall be ground, filled or treated by suitable methods.
Where permitted by local VOC regulations, Interline 982 may be applied as a primer before oxidation occurs, at a dry film thickness of 15–25 µm (0.6–1.0 mil). Dehumidification may also be used to maintain the blast standard.
Interline 982 keeps the blast standard on tank interiors in a semi-protected environment for up to 28 days. If moisture is present on the surface, oxidation occurs and re-blasting is required.
When carrying certain cargoes, Interline 984 may be applied over Intergard 269; see page 3. The maximum overcoating interval with Intergard 269 is 30 days; if the overcoating interval is exceeded (up to 90 days), the coating surface shall be abraded and washed with fresh water.
Lining system Before application of the laminate, all welds, overlaps, plate edges or other designated areas shall be filled with Interline 921.
Gelcoat application Before application of the gelcoat, the entire surface to be coated shall be abraded to remove all protruding glass fibres or other irregularities. The surface shall then be cleaned by vacuuming.
For concrete surfaces, refer to the International Protective Coatings Concrete Surface Preparation Guide for further information.

| Interruption of work | Paint must not be left 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 before resuming application. |
| Cleaning | All equipment should be cleaned immediately after use with International thinner. Flushing spray equipment periodically during the daily work is good working practice. Cleaning frequency depends on the volume sprayed, temperature and time spent, including delays. |
All surplus paint and empty containers must be disposed of in accordance with the appropriate local regulations/laws.
Before use, refer to the detailed Interline 984 application procedure.
When using Interline 984 as a glass fibre lining system, refer to the detailed Interline 984 glass fibre reinforced lining system technical specification.
The exact total dry film thickness and number of coats of the coating system depend on the service requirements. Refer to International Paint's specific recommendations for tank lining application.
Interline 984 shall be applied and inspected in accordance with the Interline 984 application procedure.
Heavily pitted areas should be pre-coated by brush to ensure good surface wetting.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
Do not apply when the steel temperature is below 10 °C (50 °F).
Unacceptably low temperature and/or high humidity during or immediately after application leads to incomplete curing and surface contamination, compromising intercoat adhesion.
The cured film must be free from pooling, sagging, runs, inclusions or other defects. All defects and faults shall be corrected. Repaired areas must be re-inspected and cured as specified before the final lining coat is placed in service. For detailed repair procedures, refer to the International Protective Coatings Interline 984 application procedure.
For commissioning, refer to the following minimum curing times for Interline 984
| Temperature | Time 1 | Time 2 |
| 10°C (50°F) | 3 days | 10 days |
| 15°C (59°F) | 2 days | 7 days |
| 25°C (77°F) | 1 day | 6 days |
| 35°C (95°F) | 18 h | 4 days |
| 40°C (104°F) | 12 h | 3 days |
The minimum times listed in Time 1 refer to the minimum curing time at the above substrate temperatures before hydrostatic testing of the tank or immersion in pure aliphatic petroleum products (e.g. diesel or kerosene, but excluding gasoline or gasoline/alcohol blends). The minimum times listed in Time 2 refer to the minimum curing time at the above substrate temperatures before immersion in products in the other resistant chemicals list.
This material is recommended for aviation fuel storage tanks. Although the mixture contains methanol, which may be harmful, it is also suitable for storage of unleaded gasoline.
Intergard 269 may be used as a tie coat only when carrying crude oil/water and refined hydrocarbons.
For storage of cargoes above ambient temperature, consult International Paint for further detailed advice.
Like all epoxy coatings, Interline 984 will chalk and fade when exposed externally. However, these phenomena will not impair its chemical resistance.
This product is approved to the following specifications: • Complies with the requirements of DEF STAN 80-97 Annex G for bulk aviation fuel tank linings.
• Spanish Norma INTA 164402-A.
• Meets the performance requirements of EI 1541, the test requirements section of EI 1530 compliance.
• DEP 30.48.00.31 - General systems LT1-N and LT1-M for crude oil service Note: VOC values are typical and for guidance only. The value may vary with factors such as colour differences and normal manufacturing 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 984 may be applied directly to properly prepared bare steel. It is also suitable for application over the following primers: Interline 982 Ceilcote 680M (sealer for concrete application) Intergard 269 This product may also be applied over Interline 921 jointing material as specified.
Interline 984 should only be recoated with itself; recoating with other products must never be carried out.
Consult International Protective Coatings to confirm that Interline 984 is suitable for contact with the product to be stored.
