International Enviroline 2405

International Enviroline 2405 is an ultra high solids, two component polycyclamine cured lining system utilising advanced epoxy technology, designed for single-leg application.

Best Uses

Enviroline 2405 is for use in the internals of steel storage tanks, pipes and vessels for service in crude oil up to 150°C (302°F).

For use under other aggressive service conditions, including high temperature produced water, consult the Product Characteristics.

Application

Recommended application is by airless spray. Brush or roller are suitable for use on small areas only.

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
Best performance will always be achieved when Enviroline 2405 is applied to surfaces prepared by abrasive blast cleaning to Sa3 (ISO 8501-1:2007) or SSPC-SP5.

Where Enviroline 2405 is not to be used in high heat and/or aggressive service, preparation to an absolute minimum of Sa2½ (ISO8501-1:2007) or SSPC-SP10 at time of coating application may be acceptable.

A sharp, angular surface profile of 75-125 microns (3-5 mils) is recommended.
Enviroline 2405 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.

The preferred method of holding the blast standard is by dehumidification. Alternatively, an approved holding primer may be used.
