International Interline 984 is a two component, solvent free, chemically resistant, heavy duty epoxy phenolic tank lining.

Best Uses

Interline 984 is intended as a lining for the protection of ferrous and non-ferrous substrates (including concrete). It may be used as a single or multi coat scheme, or as either a spray applied fibre reinforced Matcote system or a hand-lay glass reinforced system. Interline 984 has been formulated to focus on Oil and Gas downstream lining opportunities with extended recoat interval designed to assist with the contract schedules associated with lining bulk storage tanks.

Interline 984 is compliant with EI1530 (Joint Industry Group standard). This is the quality assurance requirement for the manufacture, storage and distribution of aviation fuels to airports. Interline 984 is resistant to crude oil at temperatures up to 90°C (194°F).

Interline 984 can be applied directly to correctly prepared bare steel. However, it is suitable for application over the following primer:

  • Interline 982
  • Ceilcote 680M (to be used as a sealer for concrete application)

This product can also be applied over Interline 921 caulk where this material has been specified. Interline 984 should only be topcoated with itself, and should never be overcoated with another product.


All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Where necessary, remove weld spatter and smooth weld seams and sharp edges. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Abrasive Blast Cleaning
This product must only be applied to surfaces prepared by abrasive blast cleaning to Sa2½ (ISO 8501-1:2007) or SSPC SP10. A sharp, angular surface profile of 75-100 microns (3-4 mils) is recommended. Interline 984 must be applied before oxidation of the steel occurs. If oxidation does occur the entire oxidised area should be reblasted to the standard specified above. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.

Where local VOC regulations allow, surfaces may be primed with Interline 982 to 15-25 microns (0.6-1.0 mils) dry film thickness before oxidation occurs. Alternatively, the blast standard can be maintained by use of dehumidification. Interline 982 can hold a blast for up to 28 days in the semi-protected environment of a tank interior. If moisture is present on the surface, oxidation will occur and reblasting will be required.

Laminate Systems
Prior to application of the laminate all weld seams, lap joints, plate edges or other designated areas should be caulked using Interline 921.

Gel Coat Application
Prior to application of the gel coat, the entire surface to be coated should be abraded to remove any protruding fibre glass strands or other irregularities. The surface should then be vacuum cleaned.

Concrete Surfaces
Refer to International Protective Coatings' Concrete Surface Preparation Guidelines for further information.

Apply using airless spray. Use a brush or roller for smaller areas.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
