Decks

In addition to the products mentioned, e.g. Resist 86 was used on cargo area, Barrier and Hardtop Flexi on external decks and Jota Armour on helicopter deck.

Resist 86 is moisture curing inorganic zinc ethyl silicate coating. It conforms to the compositional requirements of SSPC paint 20, level 1, ISO 12944-5 and AS/NZS 3750.15 1994. Resist 86 provides outstanding corrosion protection as a single coat or as part of a complete coating system. One of the most important features of the product is its mechanical strength, which makes Resist 86 an excellent choice for heavy-duty applications such as cargo areas.

Barrier is a two component polyamide cured zinc rich epoxy coating. It is a very high zinc dust containing product. It conforms to the compositional requirements of SSPC paint 20, level 2. It provides very good corrosion protection as part of a complete coating system. To be used as primer in atmospheric environments.

Hardtop Flexi is high solids, aliphatic acrylic polyurethane paint. It has a glossy finish with very good gloss retention. The coating is very flexible, it withstands impacts and has very good adhesion properties. Hardtop Flexi can be used both as a topcoat and as a direct-to-metal coating. The product is compliant with USA FDA Title 21, Part 175.300: approved for use with food, dry solids. Hardtop Flexi has a grain statement.

Jota Armour is a tough, abrasion-resistant polyamine cured epoxy coating, specially designed as an anti-skid coating for decks and walkways. Jota Armour combines a high solid, surface tolerant and abrasion-resistant epoxy coating with anti-skid aluminium oxide. The surface profile is rough and with a high coefficient of friction that provides exceptional non-slip properties for people and equipment. Jota Armour is pre-qualified in NORSOK coating systems (System no. 4).

Tanks

The products used in painting the tanks were e.g. Tankguard DW in potable water tanks, Jotacote Universal N10 in ballast water tanks and Marathon 2:1 in black and grey water tanks.

Tankguard DW is a solvent-free epoxy coating specially designed for drinking water tanks. It can be used as primer and finish coat in atmospheric and immersed environments. Tankguard DW has several approvals: It meets the requirements of NSF/ANSI 61-2014a Standard for Drinking Water System Components – Health Effects, requirements of BS 6920-1:2000 for contact with potable water and requirements of the Norwegian Institute of Public Health for use in contact with potable water. Tankguard DW is also in compliance with Federal Drug Authority, USA, FDA Title 21, Part 175.300, approved for exposure to dry foods and it meets the requirements of ANSI/AWWA standard C210-07: Suitable for water pipelines.

Jotacote Universal N10 is a quick drying polyamine cured epoxy coating. It is high solids, high build, abrasion resistant product. Jotacote Universal N10 also cures at low temperatures and it is designed to be used all year round in areas where fast dry to handle is required. Jotacote Universal N10 is PSPC approved for water ballast tanks and also meets the requirements of Norsok-system 3 due to its PSPC approval.

Special properties of Marathon 2:1 are excellent adhesion to the substrate, corrosion resistance and heat resistance (continuous seawater immersion at 70 °C). Marathon 2:1 also provides excellent resistance against numerous chemicals. The product is easy to paint and withstands even high film thicknesses without problems. This is important when painting confined tank spaces and it is not possible to spray from an optimal distance.
