Features & Benefits

• For professional use only
• For new build, maintenance and repair
• Good resistance to abrasion and has excellent anticorrosive and mechanical properties
• Good resistance to crude oil
• Recommended as a universal, selfprimed, high performance coating for atmospheric or immersion service, including cargo holds, water ballast tanks and cargo oil tanks to be coated according to IMO-PSPC requirements
• Intended for all year application and for in-shop applications where fast recoating and handling is required

• Also recommended for long time corrosion protection of structural steel and concrete in severe corrosive and immersed environments
• Resists normal ambient temperatures at sea when used in ballast water service (avoid long-term exposure to negative temperature gradients)
• EC-type examined as a low flame spread material when used as part of a predefined paint system
• Type approved according to PSPC requirements based on crossover testing over a wide range of shopprimers
• Complies with US FDA and EU food regulations for contact with liquid and dry foodstuff
• Short drying time giving a fast recoating and handling time
• Cures down to -10°C

Note: Product may be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate, drying and curing time and overcoating interval. For best performance, avoid excessive film thickness. If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C.

Epoxy coats have an inherent tendency of chalking in outdoor exposure. This does not affect the performance of the coating.
