ZIES218 Zinc Dust Hardener belongs to zinc-rich primers. A shop primer hardener designed for automatic spray lines, providing short- to medium-term protection for blast-cleaned steel plates or other steel structures during storage, construction and assembly. The main component is the hydrolysis product of ethyl silicate; it offers weather resistance, good welding and cutting performance, small burn-off area, good heat resistance and long protection period. Parameters on this page: dry film thickness 15–75 µm, depending on protection period requirements; theoretical spreading rate 3.77–14.36 m²/kg.

Steel surfaces: remove oil and grease with a suitable cleaner, then blast to Sa2.5 of ISO 8501:2007, with a surface profile of 40–75 µm.
The surface temperature to be coated shall be above the dew point to avoid condensation. The minimum overcoating interval depends on temperature and air relative humidity; the maximum overcoating interval depends on climatic and environmental conditions. Surfaces coated with this product shall be clean, dry and free from zinc salts before overcoating. Overcoating with alkyd, oil-based coatings and the like is not recommended.
