How temperature impacts cleaning chemistry
Effects of temperature on cleaning agents
Temperature affects solubility, reaction rates, and surface tension. Higher temperatures typically:
-
increase cleaning efficacy and reduce dwell time;
-
lower viscosity of flux residues for easier removal;
-
accelerate corrosion if inhibitors are inadequate.
ZESTRON’s datasheets specify optimal temperature ranges and expected performance gains per 10 degree Celsius increase.
Optimal temperature ranges
-
spray-in-air systems: 30-50 degrees C for most aqueous chemistries;
-
ultrasonic immersion: 40-60 degrees C to balance cavitation and evaporation;
-
solvent systems: follow solvent boiling points and safety limits.
Always test materials at target temperature and monitor evaporation and VOC emissions.
