Soldering Flux, Water Soluble, 4 oz.

Description

• LA-CO Regular Flux Paste: A non-acid, non-toxic, and lead-free white paste. It features an all-weather formula that prevents solder from “balling up” and ensures smooth flow around copper pipes. It is NSF 61 certified for use in potable water systems.
• Oatey No. 11 Liquid Flux

  : Formulated with strong cleaning agents like ammonium chloride and zinc chloride to eliminate the need for pre-cleaning oxidized copper. It is a light yellow liquid primarily used for HVAC and fine electrical work, though it is not recommended for delicate internal electrical parts.

• Oatey H-205 Water Soluble Paste Flux: A creamy, lead-free paste that remains active up to 700°F ( 371°C). It is specifically designed to resist turning copper piping green (discoloration) and is ideal for large-diameter copper systems like fire sprinklers and hydronic heating.
• Kester 2331-ZX Organic Flux

  : An innovative neutral-pH liquid flux designed for high-density circuit board assemblies. It provides superior ionic cleanliness and produces no offensive odors during heating, making it a preferred choice for telecommunications and computer hardware rework. 

• De-oxidation: Chemically reacts with and removes the “oxide skin” on metals like copper and brass, allowing for a permanent metallurgical bond.
• Improved Wetting: Reduces the surface tension of molten solder, causing it to spread evenly across the joint rather than sitting on top.
• Easy Cleanup: Because it is water-soluble, it eliminates the need for harsh chemical solvents like isopropyl alcohol or trichloroethylene during post-solder cleaning. 

• Materials: Most water-soluble fluxes are effective on copper, brass, and galvanized iron but should not be used on aluminum, stainless steel, or magnesium.
• Residue Caution: Although easy to clean, residues are often corrosive and must be removed
