Jotaguard 100
A two-component, solvent-free, polyamine-cured epoxy coating. A low-surface-preparation product not limited by the dew point, applicable on damp and wet surfaces. Has good chemical, abrasion and impact resistance. Can be used as a primer, intermediate coat, topcoat or single-coat system in atmospheric and immersed environments. Suitable for suitably prepared carbon steel, galvanized steel, stainless steel, aluminium and many aged coated surfaces.
Recommended for offshore environments, including splash zones, refineries, power stations, bridges, buildings, mining equipment and general structural steel. Only the aluminium-containing version can be used as the first coat in immersed environments.

Per Petrobras standard N-2680 'low-surface-preparation solvent-free epoxy coating for damp surfaces', the theoretical volume solids of Jotaguard 100 is 98% ± 2.
When calculating the theoretical spreading rate and wet film thickness, use 90% ± 2 as the practical value (per ISO 3233).
The resin system undergoes some shrinkage during curing. The low dry film thickness and actual spreading rate will be below the theoretical values.
The recommended surface preparation provides optimum properties including adhesion, corrosion resistance, heat resistance and chemical resistance.

When used primarily as a primer or antifouling coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
