Al Surface Treatment Agent


Etchant for AlDC Process

DAC-109DZ is a high functional Al surface treatment agent which removes oil and oxidized layer and forms even surface roughness. DAC-109DZ is an Al etchant without hydrogen embrittlement which causes lots of hydrogen gas.


• Productivity can be increased by shortened manufacturing processes
• Reduces pollution treatment cost by minimized quantity of hazardous gas and wastewater
• Micro-etching is possible; suitable for fine parts processing of electric, electronic, automobile, and aircrafts
• Increases the value of product; provides excellent polish and become corrosion-resistant after processing
• DAC-109DZ can be handled in room temperature

[ How to use ]

  • 1. Treatment process
    Degreasing (DAC-2060) → washing → etching (DAC-109DZ) → washing → desmutting (SR-893D) → washing → chrome filming (CAL-30) → washing → dry
  • 2. How to maintain product quality
    Check acidity frequently and add adequate amount of original solution when acidity is decreased during use.
  • 3. Equipment
    Use acid resistant material such as PE, PP, teflon, etc.
