International Interprime 306 is a single component, fast drying, high build alkyd shop primer that is suitable for mild to moderate corrosive environments such as schools and hospitals.
International Interprime 306 is formulated as a shop applied post-fabrication primer specifically designed for a blast, fabricate and prime steel production route, and where fast drying and rapid handling properties are required. Suitable for use in mild to moderate corrosive environments such as those typically found in commercial buildings, schools, hospitals, etc.
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. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the
appropriate manner. Interprime 306 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.
Interprime 306 can be applied over approved anti-corrosive primers. The primer surface should be dry and free from all contamination and Interprime 306 must be applied within the overcoating intervals specified (consult the relevant product data sheet). Areas of breakdown, damage etc., should be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC-SP10 Abrasive Blasting, or SSPC-SP11, Power Tool Cleaning) and patch primed prior to the application of Interprime 306.
