TekLine Flux Dispensing Bottle containing genuine Kester 1544 rosin flux is a unique tool for rework and touch-up soldering. It allows controlled application of flux, eliminating the mess from flux bottles. Dispensing tip 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. Kester 1544 Activated Rosin Liquid Flux is a homogeneous solution of high quality, purified Grade WW rosin blended into an alcohol solvent system. A very effective activating agent has been added to provide superior fluxing ability. Kester 1544 is a liquid equivalent of Kester 44 Activated Rosin Core Solder.
