The FP-300 Water-Soluble Flux Pen utilizes a spring-loaded applicator tip to deliver a controlled amount of flux to the work surface. The user friendly pin-point application is ideal for touch-up and light assembly work. To apply, simply depress the tip of the flux pen against the work area to start the flow to the applicator tip.

Unopened flux pens have a shelf life of 2 years. Flammable liquids should be stored in a dry, well ventilated environment away from open flames, sparks or direct heat.
FP-300 is an alcohol-based, water-soluble flux available in a pen and is designed for touch-ups of printed circuit boards. FP-300 cleans easily with warm DI water. For best residue removal results, clean as soon as soldering is complete
