Item Name: Nokorode Regular Paste Flux - 1lb SKU: 50102 Description: Nokorode Regular Paste Flux is a lead-free, all-purpose soft soldering paste flux manufactured by Rectorseal. This flux is formulated with a special oil base that protects against oxidation during the soldering process. The paste consistency allows for easy application to joint surfaces, and it works effectively with common solder compositions including 95/5, 60/40, 50/50, and 40/60 solders. In glassblowing and stained glass work, this flux is essential for joining copper components, such as copper foil in stained glass projects, copper wire armatures, and metal findings used in glass art. The flux promotes wetting and flow of solder, ensuring strong, clean joints that are critical for both functional and decorative applications. The 1-pound container provides ample supply for extended projects and studio use. How it is used: Apply a thin layer of paste flux to the surfaces to be soldered before heating with a soldering iron or torch Use with copper, tin, zinc, nickel, and sheet lead surfaces Works with 95/5, 60/40, 50/50, and 40/60 solder compositions Clean excess flux residue after soldering with water or a flux remover for a professional finish Ideal for stained glass copper foil work, copper wire repairs, and metal component joining in glass art projects
