International Interline 925

International Interline 925 a two component, solvent free, heavy duty epoxy tank lining. NSF Certifies to NSF/ANSI 61

Best Uses

For application to steel tank internals to provide corrosion resistance to a range of products including crude oil, white oils and potable water. Suitable for application over concrete for lining and secondary containment purposes.

NSF Certification is for tanks greater than 1000 gallons (3785 litres).

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. A sharp, angular surface profile of 75-100 microns (3-4 mils) is recommended. Interline 925 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 (0.6-1.0mils) 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.

Concrete Surfaces
Refer to International Protective Coatings for specific recommendations.
