Prefabrication Primer is a two-component, moisture curing zinc (ethyl) silicate primer specially designed for application on steel surfaces during the prefabrication stage. It provides temporary corrosion protection during storage, handling, and fabrication processes while maintaining excellent weldability and cutting properties. This primer is widely used as a shop primer for structural steel, plates, sections, and fabricated components prior to final coating application.
