International Interline 994

International Interline 994 is a two component, chemically resistant phenolic epoxy novolac tank lining.

Best Uses

International Interline 994 is suitable for corrosion protection for the internals of steel storage tanks, vessels, spools, pipes and rail cars.

This tank lining is also suitable for lining vessels containing crude oil up to 160ºC (320ºF), vegetable oils (including palm oils) for temperatures up to 90ºC (194ºF) and molten sulphur.

Application

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. For aqueous cargoes in elevated temperature service, the minimum standard of surface preparation should be abrasive blast clean to Sa3, (ISO 8501-1:2007) or SSPC -SP5. A sharp, angular surface profile of 50-75 microns (2-3 mils) is required.

The preferred method of holding the blast standard is by dehumidification. Interline 994 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.

Areas of breakdown, damage, weld seams etc., should be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC-SP10 or power tool cleaned to Pt3 (JSRA SPSS:1984) or SSPC-SP11).

Apply via airless spray. Use a brush or roller for any awkward or small areas.
