Product Description

International Intercure 324 is a two component, high solids, low VOC, epoxy zinc phosphate / micaceous iron oxide primer offering excellent barrier protection, low temperature cure and rapid overcoating properties.

Best Uses

International Intercure 324 is formulated as a primer for steelwork intended for use in a wide range of environmental conditions including offshore, chemical and petrochemical plants, industrial buildings, pulp and paper mills, power plants and bridges. The rapid curing and overcoating properties of Intercure 324 provide production flexibility, making this product suitable for use both in new construction and on site as an industrial maintenance coating.

Pigmented with zinc phosphate anti-corrosive pigment to comply with the requirements of BS5493:1977.

This product is approved for use on Highways, Network Rail New Works Systems and London Underground New Works Systems.


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. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Abrasive Blast Cleaning
Abrasive blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blasting and application of Intercure 324, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner. A sharp, angular surface profile of 50-75 microns (2-3 mils) is recommended.

Intercure 324 is suitable for application to blast cleaned surfaces which were initially to the above standard but have been allowed to deteriorate under good shop conditions for up to 7-10 days. The surface may deteriorate to Sa2 standard, but must be free from loose powdery deposits.

Shop Primed Steel
Weld seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If the shop primer shows extensive or widely scattered breakdown, overall sweep blasting may be necessary.
