Product Details

Product Description

International Interzinc 72 is a two component, metallic zinc rich epoxy primer, designed to provide excellent corrosion resistance both as a single coat and as a primer for a high performance coating system. Contains 90% zinc by weight in the dry film.

Best Uses

International Interzinc 72 is a factory or site applied primer, for use in high performance coating systems for the protection of steel in aggressive environments such as offshore structures, refineries, petrochemical and chemical plants, power stations, bridges and pulp and paper plants.

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. 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 Interzinc 72, 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 surface profile of 40-75 microns (1.5-3.0 mils) is recommended.

Shop Primed Steel
Interzinc 72 is suitable for application to unweathered steelwork freshly coated with zinc silicate shop primers. If the zinc shop primer shows extensive or widely scattered breakdown, or excessive zinc corrosion products, overall sweep blasting will be necessary. Other types of shop primer are not suitable for overcoating and will require complete removal by abrasive blast cleaning. Weld seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6.
