Here are the key factors:<br \/>1. Particle Size: Finer particles disperse better, improving defoaming efficiency.<br \/>2. Hydrophobicity: Higher hydrophobicity enhances antifoaming but may reduce compatibility.<br \/>3. Temperature: The Optimal range is 10\u201360\u00b0C (depending on carrier material). Excessive heat may degrade active components.<br \/>4. Storage Conditions: Moisture absorption reduces effectiveness (stored in dry, sealed containers). Long-term storage may cause settling or clumping.<br \/>5.
