Kester 5252M Cleaner is a halogen-free, organic solvent developed for cleaning applications. 5252M is not ozone depleting and is environmentally friendly. It is a suitable substitute for chlorinated solvents used in cleaning applications where fast air-drying is critical. 5252M is most effective on the removal of post-soldering flux residues and other organic contaminants from electronic assemblies. It can also be used as a solvent to clean stencils efficiently. 5252M also readily dissolves misprinted and reflowed solder pastes and wave-soldered flux residues. It is a more effective cleaner than propanol and other commonly used solvents. 5252M provides rapid, effective and safe cleaning action. This cleaning solvent is a non-ionic and relatively non-toxic liquid with mild odor.
