Product Description

International Interprime 539 is a single pack modified polyvinyl butyral / phosphoric acid etch primer free from zinc chromate. Ideal for use as a pretreatment primer above water.

Best Uses

International Interprime 539 is suitable as an above water pretreatment primer designed to promote subsequent topcoat scheme adhesion to, and seal the surface of non-ferrous metals. Interprime 539 is particularly suitable for priming galvanised steel surfaces. For use at Newbuilding, Maintenance & Repair or On Board Maintenance.

Available in VTA538 Yellow in 5 Litres.


Use in accordance with the standard Worldwide Marine Specifications. All surfaces to be coated should be clean, dry and free from contamination. High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.

The preferred method of treating most non-ferrous and galvanised surfaces prior to application of International Paint systems is to brush blast or abrade following treatment as described above. When blast cleaning is employed, a low air pressure should be used with a fine grade of abrasive (0.2-0.5 mm) suitable for the substrate and the nozzle held 1 metre (3 feet) from the surface. Interprime 539 should only be used when this is not possible.

Preparation of Non-Ferrous Metals
Ensure surface is clean, dry and free from metal corrosion products. When the substrate is aluminium or a light alloy, the surface should be solvent cleaned and then etched chemically using Interprime 539. It is important to follow the application of Interprime 539 with a paint system appropriate to the painting of aluminium (consult our technical team).

Preparation of Galvanised Steel
Degrease to SSPC-SP1 and remove any white zinc corrosion products by hand or power tool cleaning.

This material is a one pack coating and should always be mixed thoroughly with a power agitator before application. Apply using airless spray, conventional spray, brush or roller.
