U-POL 0789 WELD#2 Weld-Through Primer, Zinc Rich, 450 ml Aerosol

U-POL 0789 WELD#2 Weld-Through Primer, Zinc Rich, 450 ml Aerosol

• U-POL 0789 WELD#2 Weld-Through Primer is a zinc rich, conductive aerosol primer designed for use on panels prior to resistance spot, MIG, and TIG welding. It helps provide rust and corrosion protection and supports weldability on properly prepared metal substrates.
• Features:
  • Zinc rich conductive weld-through primer designed for panels prior to resistance spot, MIG, and TIG welding.
  • High concentration of zinc in the dry film supports electrical conductivity for welding operations.
  • Corrosion resistant primer layer helps protect metal surfaces in overlap areas and weld zones.
  • Clog free nozzle helps maintain consistent spray performance for small repairs and panel work.
  • Fast drying formulation helps reduce wait time between application and welding on suitable substrates.

Q: What is U-POL UP0789 WELD#2 primarily used for?
A: It is a weld-through primer applied to suitably prepared panels before resistance spot, MIG, or TIG welding to support conductivity while helping provide corrosion protection in overlap and weld areas.

Q: What substrates can this weld-through primer be applied to?
A: It is designed for direct to metal applications and is listed for use on galvanized and aluminum when the surface is properly cleaned, degreased, and prepared.

Q: How many coats should be applied?
A: Apply 1-2 coats, allowing a short flash time between coats, to build a thin conductive film suitable for welding operations.

Q: Does UP0789 have a related variant?
A: Yes. The WELD#2 line also includes UP0768, which is the copper version in the same 450 ml aerosol format.
