Nu-Calgon 4087-03 Zinc Rich (13 ounce can)
Zinc Rich Cold Galvanizing is highly resistant to all forms of corrosion. Through galvanic action, small scratches “heal” themselves. Perfect where factory galvanized finish is damaged in shipment, assembly, welding, etc. Blends well with hot-dip coating. Forms a zinc film that by electro-mechanical reaction literally fuses itself to iron, steel, and aluminum.
Typical uses: Rust-proofing all welds, air conditioning and heating ducts, sumps, iron, pipes, structural steel work and fan blades, chemical and oil refineries, farm equipment, sign equipment, and anywhere metal is subject to corrosion and rust. Does not contain pvc monomer.
