Product Description

International Interzinc 42 is a two component, metallic zinc primer for steel in aggressive environments.

Best Uses

As a zinc primer for application as part of a coating system for structures in aggressive environments in a wide range of industries, including offshore facilities, petrochemical plants, pulp and paper mills, bridges and power plants. Interzinc 42 has been designed for use in maintenance situations and as a primer at new construction.

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 42, 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 Steelwork
Interzinc 42 is suitable for application to 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 SSPCSP6.
