Flussante Kester 979VOC-Free No-Clean a base acquosa.Tanica da 5Lt

Kester 979 is a completely new, organic, no-clean flux formulation for high quality, low-defect

soldering of electronic circuit board assemblies. Its chemistry is free of any volatile organic
compounds (VOCs), solvents that may react photochemically to form air pollution (smog).
This flux's finely tuned activation system offers the best wetting available in VOC-Free liquid
flux technology and the shiniest solder joints. Kester 979 offers excellent soldering properties
that lead to higher productivity without sacrificing reliability of the assembly. Kester 979 also
reduces microsolderballing on glossy laminates and between connector pins.
Classified as ORL0 per ANSI-J-STD-004, Kester 979 will not attack properly cured solder
masks or FR-4 Epoxy-Glass laminate. After its use, the cosmetic appearance of the board's
surface is excellent. For example, Kester 979 leaves no haze or visible residue behind,
including the white powdery residue associated with use of earlier no-clean formulas.

The miniscule amount of non-visible residue that remains after soldering is non-conductive, noncorrosive
and does not have to be removed. In addition, the residues will not interfere with incircuit
testing probes. Kester 979 is not detrimental to the Surface Insulation Resistance (SIR)
of the soldered assembly. If the user still chooses to clean the circuit board assembly because of process considerations, the minute amount of non-visible residue can be washed easily with plain, warm water (110-130°F).
