Kester 1544 is an activated rosin liquid flux. It is a homogeneous solution of high quality, purified rosin blended into an alcohol solvent system. A very effective activating agent has been added to provide superior fluxing ability.

CML Supply purchases Kester 1544 flux in bulk quantities from an authorized distributor and repackages this flux in smaller quantities for use in convenient dispensing pens.

Liquid flux in a dispensing pen is a unique tool for rework and touch-up soldering. It allows controlled application of flux, eliminating the mess from flux bottles. Chisel point allows for work in very confined spaces. Ideal for solar tab assembly and surface mount rework because it can deliver flux to a specific area.
