ZICG221 Cold Galvanizing Coating belongs to Cold Galvanizing. Cold galvanizing coating is a new type of coating that achieves a room-temperature "galvanizing" process with a single-component coating. The zinc dust content in the dry film reaches 96% or above, providing anti-corrosion performance equivalent to hot-dip galvanizing. Single-can, gray zinc-rich heavy-duty anti-corrosion primer. Parameters on this page: dry film thickness 30 µm, theoretical spreading rate 5 m²/kg, number of components single-component.

Single-can, gray zinc-rich heavy-duty anti-corrosion primer. Good heat resistance and weldability.
Cold galvanizing coating is a new type of coating that achieves a room-temperature "galvanizing" process with a single-component coating. The zinc powder content in the dry film reaches 96% or more, providing anti-corrosion performance equivalent to hot-dip galvanizing. It is applied to the maintenance of old galvanized layers and replaces hot-dip galvanizing in the anti-corrosion protection of steel components in various fields, with a corrosion protection life of 30 years or more.
