6-3 High Purity Water-based Flux

6-3-1 6602 Characteristics

“Focus on the environmental protection and provide eco-friendly products”is the target of Zhongya. For this purpose, a kind of water-based halogen-free flux was developed for the wave soldering by ourselves. This product meets the ISO14001 standard and RoHS directive. The wettability of this product is similar to the organic solvent flux. However, this product is safer and cheaper than the organic solvent flux.


  1. Halogen-free.
  2. Safe and non-flammable.
  3. No volatile organic solvent and the content is very stable
  4. Dispense with dilution before use.
  5. Lower solid content and lower residue after soldering.
  6. Colorless、inodorous and non-toxic
  7. Excellent solder ability, the joint is full and bright after soldering.
  8. Safe and easy for transit and storage

This product meets the GB/T9491-2002, ANSI/J-STD-004 and MIL-F-14256D standard, and has passed the SGS certification. The application fields: Computer main board and related parts, communication equipment, video/audio products, electronic toys, home appliances, etc.
