International Interchar 1190
International Interchar 1190 provides up to two hours cellulosic fire protection on beams, columns and hollow steel sections exposed in interior environments.
Best Uses
International Interchar 1190 is formulated as a single component, borate and chlorine free, water borne intumescent coating designed for on-site application to structural steel requiring protection from cellulosic fire.
Interchar 1190 is a low VOC acrylic intumescent material independently fire tested in accordance with BS 476 Parts 20-22.
Application
All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application, all steel 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.
Primed Steelwork
Interchar 1190 should always be applied over a recommended anti-corrosive coating scheme. The primer surface should be dry and free from all contamination and Interchar 1190 must be applied within the overcoating intervals specified (consult the Interchar 1190 Application Guidelines). Areas of breakdown, damage etc., should be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC-SP6, Abrasive Blasting, or SSPC-SP11, Power Tool Cleaning) and a full coat of primer applied prior to overcoating with Interchar 1190.
Metallic Zinc Primed Surfaces
Interchar 1190 can be applied over approved epoxy metallic zinc primers, provided that these have been overcoated with an approved tie coat. Ensure that the primed surface is clean, dry and free from contamination prior to application of the Interchar 1190.
Recommended tie coats are International Intergard 269 or International Intergard 276.
