·R59 · Vaal Triangle · JHB SouthImmersion-grade epoxy mastics from Jotun — formulated for the toughest underwater, immersed and splash-zone service in South African industry.
A mastic is a thick, high-solids epoxy coating specifically formulated to withstand immersion without blistering, disbonding or chemical degradation. The term refers to its consistency — thicker than regular epoxy, easier to apply to rough surfaces, and more forgiving of surface preparation.
For tanks storing water, fuels or chemicals, an immersion coating is essential. It prevents corrosion from the inside, stops chemical attack, and resists the osmotic pressure that causes standard coatings to fail.
The reference for general immersion service. Two-component epoxy mastics formulated for tanks, pipelines, water treatment and offshore use. Excellent adhesion even on damp, poorly prepared surfaces — critical in the field. JOTAMASTIC 90 offers better tintability and higher performance.
ApplicationsStorage tanks, water pipelines, immersion zones, process vessels
The premium choice. A solvent-free epoxy at 98% solids — minimal VOCs, minimal shrinkage and unmatched chemical resistance. Designed for internal tank linings, chemical storage and the most demanding immersion environments.
ApplicationsInternal tank lining, chemical storage, potable water, high-exposure environments
A specialised formulation for above-ground and below-ground storage tanks. Excellent colour retention, UV resistance for above-ground exposure, and long-term protection of stored contents.
ApplicationsAbove- and below-ground storage tanks
Barrier protection blocks moisture and chemicals from reaching steel. Chemical resistance handles acids, alkalis, oils and process chemicals. Adhesion holds even on damp, poorly blasted surfaces. And osmotic-pressure defence prevents the blistering that destroys lesser coatings.
