Fire Retardant Coating · Paint & Coating Systems

Class-certified type (DNV register) · technical data sheet not yet verified

International / AkzoNobel Interchar 212 is a fire retardant coating. It is applied to the vessel structure or equipment surface specified by the coating scheme, such as hull, ballast tank, cargo tank, deck or machinery areas. Its purpose is to protect the substrate against corrosion, fouling, chemicals, weather, slip or fire exposure according to the listed coating type. Performance depends on surface preparation, compatible primer and topcoat layers, application conditions, curing and total coating-system compatibility. The exact product designation distinguishes resin chemistry, service environment and approved coating scheme from neighboring products; refer to the manufacturer documentation for the exact figure.

Service

Service notes.

What our service work and the manufacturer documentation say about keeping this model running.

Inspect coated surfaces for blistering, rusting, cracking, peeling, mechanical damage and edge breakdown. Identify and remove the cause of moisture, contamination or chemical attack before local repair. Prepare the substrate and apply compatible repair coats according to the approved coating specification. Maintain batch, mixing, curing and environmental records where required by the vessel coating plan. Pay particular attention to welds, edges, drains and high-abrasion zones. Refer to the manufacturer documentation for the exact figure for surface preparation, dry-film thickness, curing and overcoating requirements.

Inspection

Common failures & inspection points

Blistering caused by moisture, osmotic contamination or poor surface preparation, resulting in raised bubbles and localized coating loss
Delamination caused by inadequate surface preparation, contamination or incompatible overcoating, resulting in peeling or loss of adhesion
Underfilm corrosion caused by coating damage, holidays or poor edge coverage, resulting in rust staining and progressive coating breakdown
Cracking or embrittlement caused by excessive film build, aging or substrate movement, resulting in visible cracks and loss of barrier protection
Abrasion, impact or chemical attack caused by service exposure, resulting in worn areas, discoloration or exposed substrate

Replacement Parts

Spare parts notes

Keep compatible primer, intermediate and topcoat materials required by the vessel coating scheme together with approved thinners, repair materials and application consumables. Coating shelf life and storage conditions must be respected. Do not substitute a different coating chemistry without compatibility and approval checks.
