Kester5768
Kester 5768 Bio-Kleen® is a highly concentratedliquid cleaner which is added to water to make anon-foaming solution for removing rosin fluxresidue. The alkaline chemicals in Kester 5768
react with rosin by a chemical conversion knownas saponification to form soaps which arewater-soluble. The resulting rosin soap and anywater-soluble residue, such as activator salts, can
then be rinsed away with water. Kester 5768possesses enhanced ability to solubilize unsaponifiable material that is normally present in
rosin and in additives used in some flux orsolderpaste formulations. This assures excellentvisual and ionic cleanliness of circuit boards aftercleaning. A significant feature of this formulation is
its stable composition during use at elevated temperatures such that a greatly increased operating life is achieved. This results in less
frequent discharge of the wash tank for replacement with fresh solution and in a process cost reduction. Another special feature of Kester
5768 is that unlike other saponifier products which tend to mildly etch the solder surface, it leaves joints bright and shiny after cleaning. Kester 5768
eliminates the need for expensive, toxic and environmentally harmful solvents traditionally used for flux removal.
