Defluxer Agent
CAS Number: 111-76-2
Defluxer agent is a specialized solvent or aqueous solution formulated to dissolve and remove flux residues from PCBs and electronic assemblies after soldering operations. It effectively targets rosin-based, water-soluble, and no-clean flux residues while being safe for sensitive components and substrates. Available in aerosol, liquid concentrate, and ready-to-use formats.
