Galvanite™
Repair Galvanizing Right with Lead-Free Galvanite™

Galvanite™ solder is a new lead-free formulation designed specifically for high quality repairs to galvanized steel surfaces. Galvanite™ is simple, effective and easy to use, in both manufacturing and field applications. Just like the original galvanizing, Galvanite™ metallurgically bonds to the steel, for a seamless protective barrier. Galvanite™ exceeds performance standards as specified by ASTM standard A780-92 for repair of galvanized coatings.

Benefits and Uses

Galvanitetm has been designed to accomplish three important objectives:

  • Provide excellent cathodic and barrier protection, far superior to zinc paints and alternative lead solders in abrasion resistance, adhesion and hardness,
  • Allow easy application at low temperatures with any heat source,
  • Produce a lead-free composition to address environmental and health concerns.

General Procedure

Prepare the surface to be repaired by sanding or wire brush.

Galvanite™ has a broad slushy range of 390°F to 570°F (200°C to 300°C). When heated, the slurry can be shaped and spread easily to blend seamlessly with the existing galvanized coating. The slurry can be built to a substantial thickness, even on vertical surfaces.

Hot Dip Galvanizers:

Small defects in the surface of freshly galvanized steel can be easily repaired with Galvanite™. Typically, residual heat is sufficient to melt and apply Galvanite™. The high zinc content provides excellent cathodic protection and the repair blends and bonds with the original galvanizing.

Fabricators and Welders:

In the shop and field, galvanized surfaces are often damaged by cuts and welds. Due to its moldable nature, Galvanite™ can be applied to a substantial thickness in almost any orientation. The solder penetrates deep into cracks and imperfections to provide a seamless protective barrier.
