Product Description

International Interlac 789 is a single component, rapid drying modified alkyd primer / finish, designed to provide both anti-corrosive properties and a decorative finish in a single coat.

Best Uses

International Interlac 789 has been designed for use as a single coat system to afford anti-corrosive protection for structural steelwork exposed to the environment where cosmetic appearance is important, e.g. in dry internal areas or low corrosivity external environments.

International Interlac 789 is particularly suited for use as a rapid drying versatile primer/finish designed to maximise the steel throughput in fabrication yards.


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 Interlac 789, 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.

Interlac 789 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.

This material is a one component coating and should always be mixed thoroughly with a power agitator before application.
