International Intercure 420 is formulated as a high build intermediate to provide excellent barrier protection as part of a high performance system suitable for use in aggressive environments including offshore, bridges, chemical and petrochemical plants, power stations, pulp and paper mills and industrial building.
Intercure 420 can be used as a barrier coating applied direct to steel where the environment is non-aggressive. The incorporation of plate-like micaceous iron oxide pigment both increases the barrier effect and improves long term overcoating properties of the system making this material ideally suitable for application in the fabrication shop, prior to shipping, with final overcoating at site. The rapid curing and overcoating properties of Intercure 420 provide production flexibility, making this product suitable for use both in new construction and on site as a maintenance coating.
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 Grit Blast Cleaning
Abrasive grit blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blasting and application of Intercure 420, 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.
Primed Surfaces
All suitable primers for use under Intercure 420 should be applied over grit blast cleaned surfaces to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. A sharp, angular surface profile of 50-75 microns (2-3 mils) is recommended.
Shop Primed Surfaces
Weld seams and damaged areas should be grit blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If the shop primer shows extensive or widely scattered breakdown overall grit sweep blasting may be necessary. If the shop primer was applied over shot blasted surfaces, overall grit sweep blasting will be necessary prior to application of Intercure 420.
Metallic Zinc Primed Surfaces
Ensure that the surface of the primer is clean, dry and free from contamination and zinc salts before application of Intercure 420. Ensure zinc primers are fully cured before overcoating. If the zinc primer was applied over shot blasted surfaces, overall grit sweep blasting will be necessary prior to application of Intercure 420.
Abrasive Blast Cleaning
Abrasive blast clean to SA2 1/2 (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blasting and application of Intercure 420HS, 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.
