Kester Water Soluble Flux Pen 2331ZX

The Kester 2331ZX is a 10mL water soluble flux pen engineered for professional electronics assembly work on both leaded and lead free circuit boards. This flux pen handles SMT rework, conventional PCB assembly, and through hole soldering applications with consistent performance across production and repair environments. After soldering, the flux residue washes away cleanly with water and produces minimal foaming in standard water cleaning systems, reducing both labor time and cleaning costs. As an environmentally compliant formulation, the 2331ZX meets modern manufacturing standards while delivering the reliable precision that professional electronics shops and production teams depend on.
