ZD8580 Silicone High-Temperature Coating 600 °C is a high-temperature coating, in the silicone coating system. Used for high-temperature corrosion protection of the outer walls of blast furnaces and hot blast stoves; it can also be used for chimneys, flues, exhaust pipes, high-temperature hot gas pipelines, heating furnaces, heat exchangers and other metal surfaces requiring high-temperature corrosion protection. Composed of silicone resin, special temperature-resistant anticorrosive pigments, additives and organic solvents. Parameters on this page: volume solids ≥ 45%, dry film thickness 20 µm, theoretical spreading rate 70 g/m². Comparable models from the same brand: ZD8580 silicone high-temperature coating 400 °C, ZD5180 high-solids polyurethane topcoat, ZD53-62A epoxy micaceous iron oxide intermediate coat.

| New steel | Remove grease with a suitable cleaner and rinse salts and other contamination off the surface with fresh water. Remove weld slag, grind welds and sharp edges smooth, and blast clean to Sa2.5 (ISO 8501-1), ideally achieving a surface profile of Rz 30–75 µm (medium profile on the ISO 8503-1 comparator). Apply the primer within 4 hours of blasting. Steel may also be abraded to St3. |

Note: the above data are measured under well-ventilated conditions, at typical film thickness and 65% relative humidity, and are for reference only.
Actual drying times and the interval before recoating may be longer or shorter depending on film thickness, ventilation, humidity, the underlying paint, requirements for early handling and mechanical strength, and other factors. The coating must be fully cured before immersion service.
