Interline 2981 is primarily designed for the storage market in refineries, tank farms and associated pipelines where a broad spectrum of chemical resistance is required between extended inspection and maintenance intervals.
The recommended application method for this product is by Airless Spray. A brush can be used for stripe coats only, however the use of a roller is not recommended.
Interline 2981 is developed primarily for application by single or twin feed airless spray, and does not require an induction period, therefore minimizing application time.
Ensure all surfaces are clean, dry and free from contamination. Prior to application, all surfaces should be assessed and treated in accordance with ISO 8504:2000. Where necessary, remove weld spatter and where required, smooth weld seams and sharp edges. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.
Steel Substrates
This product must only be applied to surfaces prepared by abrasive blast cleaning to Sa2½ (ISO8501-1:2007) or SSPC-SP10. A sharp, angular surface profile of 75-100 microns (3-4 mils) is recommended. Interline 2981 must be applied before oxidation of the steel occurs. If oxidation does occur, the entire oxidised area should be re-blasted to the standard specified above. Any surface defects that are revealed by the blast cleaning process should be ground, filled or treated in the appropriate manner.
When self-self overcoating, ensure the surface of the existing Interline 2981 has been fresh water washed and allowed to dry, prior to second coat application.
Where local VOC regulations allow, surfaces may be primed with Intergard 269 to 25-40 microns (1.0-1.6 mils) dry film thickness before oxidation occurs.
Intergard 269 may hold the blast for up to 6 months in the semi-protected environment of a tank interior. If moisture is present on the surfaces, oxidation will occur and re-blasting will be required.
Intergard 269 may be used as a holding primer for Interline 2981. The Intergard 269 should be clean, dry and intact and within a maximum 6 months from application.
