Jotun Barrier 80 is ideal for structural steel and piping exposed to a wide range of corrosive atmospheric environments up to very high. Recommended for offshore environments, refineries, power plants, bridges, buildings, mining equipment and general structural steel. Suitable for carbon steel, repair of inorganic zinc silicate coating and damaged galvanised substrates. The product conforms to the compositional requirements of SSPC paint 20, level 2 and ISO 12944 and the zinc pigments comply with ASTM D520 type II zinc dust. Specially designed as a primer in coating systems where extended durability is required. Suitable for exterior exposure in offshore environment, below 120 °C.
When preparing new surfaces, maintaining already coated surfaces or aged coatings it is necessary to remove all contamination that can interfere with coating adhesion, and prepare a sound substrate for the subsequent product. Inspect the surface for hydrocarbon and other contamination and if present, remove with an alkaline detergent. Agitate the surface to activate the cleaner and before it dries, wash the treated area using fresh water. Paint solvents (thinners) shall not be used for general degreasing or preparation of the surface for painting due to the risk of spreading dissolved hydrocarbon contamination. Paint thinners can be used to treat small localized areas of contamination such as marks from marker pens. Use clean, white cotton cloths that are turned and replaced often. Do not bundle used solvent saturated cloths. Place used cloths into water. When the surface is an existing coating, verify with technical data sheet and application guide of the involved products, both over coatability and the given maximum over coating interval.New surfaces should be cleaned to a minimum of SA2.5. When applicable, products primarily meant for use as primers or anti-fouling may have slight colour variations from batch to batch. Such products may fade and chalk when exposed to sunlight and weathering. A zinc epoxy should be applied in a smooth and even film. Too rough film could give risk of popping when the subsequent coat is applied. Film thickness exceeding recommended maximum may cause mud cracking and poor film integrity. Sufficient ventilation is very important to ensure proper drying/curing of the film. Refer to data sheets for application guide.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
