Superior RubyFluid Flux
Superior RubyFluid is a water-soluble flux formulated for soldering. The flux is a non-fuming, self-cleaning soldering flux. The flux exerts a strong scavenging action to remove oxide coatings and other impurities from the metal surface to produce strong joints. Pre-cleaning is not necessary under most conditions.
The flux exhibits the best activity between 200-600°F. Post-solder residues are water-soluble and hot water rinses (140°F or higher) may be adequate for most applications.
