Browse Similar Models by CategoryThis model belongs to: Fire Protection, Epoxy

Product description

A high-performance, high-build, solvent-free, two-component modified epoxy intumescent fire protection coating, designed to protect steel structures in cellulosic fires.

Independently fire-tested and complies with the following standards: UL 263/UL 2431 classification Category I-A external exposure requirements, BS 476 Parts 20-22, GOST (Russia), EAD 350402-00-1106, Korean Standard F 2257, Australian Standards AS 1530.4 (2014) and AS 4100.

Interchar 212 is applied off-site with professional spray equipment, achieving the required fire protection in only one to two coats (e.g. 2 hours). The product has excellent anti-corrosion and mechanical properties. Unlike many other products on the market, Interchar 212 requires no additional surface coating and no reinforcement to provide complete fire protection for steel structures.

Interchar 212 is a spray-applied material that requires no additional reinforcement in service.

Intended use

Helps maintain the integrity of steel structures in cellulosic fires. Typical structures requiring this protection include many public access facilities, such as airport terminals, leisure facilities, conference centres, educational facilities, shopping malls, industrial plants and hotels.

Interchar 212 uses durable epoxy technology to provide off-site fabrication and fire protection material for steel structures, away from the construction site. This not only helps optimise quality management but also shortens the construction period.

Application data

*Consult AkzoNobel for more information. All drying time data is based on a typical thickness of 3.5 mm.

Regulatory compliance data

Surface Preparation

All surfaces to be painted must be clean, dry and free of contaminants. Before painting, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.

The steel surface must be abrasive blast cleaned and a modified primer applied. The blasting requirements should be consistent with those for the primer in the technical data sheet. General blasting requirements should achieve Sa 2½ (ISO 8501-1:2007) or SSPC-SP6, producing a minimum roughness of 50 µm (2 mils). The choice of primer depends on the environment in which the fire protection system is used.

Interchar 212 can be applied to galvanized steel structures. The steel surface must be blasted to produce a roughness approaching Sa 1 (ISO 8501-1), SSPC-SP7 or NACE No. 4. Normally blasting produces a roughness of 15–25 µm; the primer should be applied immediately after blasting.

Application

Before application with a two-component spray pump, keep each component at 30–34 °C (86–93 °F) for 24 hours (up to 48 hours maximum).

Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.

Product Characteristics

Before using Interchar epoxy coatings, the "Recommended Application Procedure" must be carefully reviewed. In addition, International Paint must be contacted as required to ensure that training in the application and use of the coating can be arranged if needed. The product application guide provides additional information on the product and should be used together with the product data sheet. International Paint recommends applying this coating with plural-component equipment; using other application methods will result in higher consumption and waste.

When applying Interchar 212 in confined spaces, ensure adequate ventilation.

The final surface appearance of the product depends on the application method.

Do not apply this product when the steel temperature is below 5 °C (41 °F). This product will not cure below 5 °C (41 °F). For ideal performance, the ambient curing temperature should be kept above 10 °C (50 °F). The surface to be coated must be at least 3 °C (5 °F) above the dew point.

As with all epoxy coatings, external exposure of Interchar 212 will cause chalking and discolouration. These phenomena do not impair fire protection performance. Where an aesthetically pleasing finish is required, a recommended topcoat should be applied.

With multi-coat systems, keep the recoat interval as short as possible to achieve ideal intercoat adhesion.

International Paint can provide on-site service; however, it is the responsibility of the application contractor to notify International Paint of the scheduled application date. If on-site service is provided, quality control remains the responsibility of the applicators, but must at least comply with the procedures specified by the customer and International Paint.

Interchar 212 is certified to the following standards: • BS 476 Pt 20-22:1987 fire rating up to 2 hours • GOST Russia, fire rating up to 2 hours • UL 263 (exterior listing) USA, fire rating up to 3 hours • EAD 350402-00-1106 - continental Europe, assessed up to 2 hours (ETA-1-/0470) • Korean Standard F 2257 - fire rating up to 2 hours • Australian Standards AS 1530.4-2014 and AS 4100.

Note: the VOC value given is based on the maximum possible value for the product and may vary with colour and general production tolerances.

Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
