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.
