Why choose this product

High-Quality, Water-Soluble Formulation

La-Co WaterSoluble Flux is a lead-free, organic paste designed for safe, effective soldering. Its water-soluble nature ensures easy cleanup, reducing residue and environmental impact. Supported by NSF-61G and ASTM-B813 standards, it offers reliable performance in Indian weather, even in high humidity or temperature fluctuations.

Ideal for Copper & Brass in Indian Conditions

This flux supports copper-to-copper and copper-to-brass joints, crucial for plumbing and electronics in India. Its low working range below 800°F makes it compatible with common soldering tools, ensuring strong, durable bonds suitable for professional and DIY projects. Skip if working with leaded solders or high-temperature alloys.

How to use

  • Prepare surfaces — Clean copper or brass surfaces thoroughly. Apply a thin, even layer of La-Co water-soluble flux with a brush or applicator before soldering.
  • Heat and solder — Heat the joint area below 800°F. Apply solder until joint is strong and clean, ensuring good wetting and minimal residue.
  • Clean up — After soldering, rinse with water to remove flux residue. Wipe dry for a clean, professional finish.
