International Interchar 2090

International Interchar 2090 is formulated to provide up to 2 hours fire protection on 'I' sections beams (including cellular beams), columns and hollow sections.

Best Uses

International Interchar 2090 is a single component, solvent borne, borate free, high solids, low VOC intumescent coating designed to provide fire protection to structural steelwork.

Independently tested at accredited laboratories to BS476 Parts 20-21 and third party assessed and certified.

International Interchar 2090 is suitable for both off-site and on-site application due to its ease of use, fast drying and handling properties. Can be used over a wide range of approved priming systems.

A version with greater water resistance is available which allows for Interchar 2090 to remain untopcoated for up to 6 months exterior exposure provided there is no pooled/heavy running water, or frequent high humidity conditions.

Application

All steel 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.

Primed Surfaces
Interchar 2090 should always be applied over a recommended anti-corrosive coating scheme. The primer surface should be dry and free from all contamination and Interchar 2090 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 SP6 Abrasive Blasting or SSPC SP11, Power Tool Cleaning) and patch primed prior to the application of the product. Consult the Interchar 2090 Application Guidelines for more details regarding surface preparation.

Metallic Zinc Primed Surfaces
Interchar 2090 can be applied over approved epoxy metallic zinc primers. Ensure that the primed surface is clean, dry and free from contamination and zinc salts, prior to application of the Interchar 2090. Ensure zinc primers are fully cured before overcoating. The use of a tie coat, typically Intergard 269 or Intergard 276, is recommended to prevent accumulation of zinc salts.

Apply via Airless Spray or Brush.
