In the metal processing and surface treatment industry, excessive foam is a common challenge in cleaning processes. Persistent foam not only reduces cleaning efficiency, causes tank overflow and waste, but may also affect subsequent treatments and lead to surface residues. Addressing this issue, Chemi Tech has developed a series of defoamers specifically designed for metal cleaning, leveraging technological innovation and scenario-based applications to help enterprises achieve efficient, stable, and economical cleaning processes.

Market Pain Points:
Traditional cleaning processes often generate stubborn foam due to surfactants, alkaline additives, or mechanical agitation. This foam reduces effective tank volume, impairs spray system efficiency, and may interfere with automated equipment. Moreover, foam can carry contaminants back onto workpiece surfaces, compromising the quality of subsequent processes such as electroplating or coating.
Chemi Tech Solution:
1. Rapid Defoaming and Long-Lasting Suppression: Modified polysiloxane and special carrier technology instantly break surface foam and inhibit recurrence, even in harsh conditions like high temperatures and strong alkalinity.
2. Compatibility and Safety: Compatible with various cleaners (acidic, alkaline, neutral) without affecting cleaning performance, and non-corrosive to metal materials.
3. Precise Dosing Guidance: Provides dynamic dosing recommendations and concentration control based on cleaning methods (e.g., ultrasonic, spray, immersion), avoiding overuse.
Application Case:
A precision component manufacturer faced severe foam overflow during pre-anodization cleaning, requiring 2-3 daily shutdowns for foam removal, significantly reducing productivity. After adopting Chemi Tech KM-812 series defoamer, foam volume decreased by over 90%, tank utilization increased by 25%, and workpiece surface cleanliness improved notably, resulting in an 18% boost in anodizing yield.
Usage Steps:
① Add defoamer at 0.1%-0.5% ratio based on tank volume and foam severity;
② Inject directly into the circulation system or add after pre-dilution;
③ Regularly monitor foam height and supplement defoamer when replenishing 1/3 of cleaner.
Chemi Tech specializes in industrial defoaming, offering end-to-end services from sample testing and on-site debugging to continuous optimization, delivering reliable technical support for the metal cleaning industry.
