AQUANOX® A4625 - Aqueous In-Line Cleaning Solution
Easy to use, AQUANOX® A4625 is environmentally friendly, has a long tank life and is safe for multi-pass applications.
AQUANOX® A4625 is a highly dispersive cleaning agent engineered to remove lead-free no-clean flux residues. AQUANOX® A4625 is formulated with high dispersive, moderate polarity, and moderate hydrogen bonding forces. AQUANOX® A4625 is effective on greater than 90% of the solder pastes in production today. A4625 is commonly used to clean rosin and no-clean flux residue types but will also clean water soluble soils.
AQUANOX® A4625 solvency make-up is engineered with a mixture of oxygenated alcohol-ether compounds, which are partially soluble in water. The solvents were selected on their ability to dissolve rosin and resin structures. The solvents provide a unique hydrophobic (rosin/resin loving) and hydrophobic (water loving) balance. The operating concentration range for water soluble soils is 5-10%, 10-15% for rosin-based soils, and 13-18% for no-clean soils.
The concentrated AQUANOX® A4625 contains no water or inorganic salts. The high level of solvency within the A4625 concentrate provides high dispersive values at the dilution concentration ranges. The solvent micro-droplets at operating wash temperatures ranging from 130-155°F provide high affinity for non-polar resin and rosin structures.
AQUANOX® A4625 contains low levels of a polar organic reactive solvent with one side of the molecule inducing the ion-dipole on non-polar resins and the other portion of the molecule providing dispersive forces. These unique properties provide affinity for both ionic and non-ionic solutes. Functional additives are added to reduce interactions on metallic alloys, anodized aluminum, and conversion coatings. The pH ranges from 9.5-10.5 dependent on the in use concentration.
AQUANOX® A4625 is designed for use in spray-in-air cleaning equipment. The operating concentration varies with the soil type. A4625 is a low foam cleaning agent that is commonly monitored based on the solvent / water ratio. Wash time is a function of the soil, component geometry and Z-axis gap. Lower Z-axis gaps under components typically require longer wash times.
AQUANOX® A4625 has proven compatible with all materials commonly used in electronic assembly manufacturing and cleaning processes. For specific compatibility information, please contact your Kyzen representative.
