Waterproof coating liquid HPW-5185


  • Waterproof coating for smart phones and tablets
  • Waterproof coating for digital cameras
  • Waterproof coating for automotive parts and home appliances
  • Waterproof coating for smart meters


  • Eco-friendly due to its one-component type (Water+acrylic base) (No hardener)
  • Thermosetting instead of UV curing to reduce implementation costs
  • Excellent waterproofing properties due to cross linking of dual activated cells and the polymer, accompanied by evaporation of moisture
  • Excellent alkali resistance and acid resistance
  • Passed all IPA resistance, exposure, and salt spray tests
  • Excellent heat resistance (250℃)
  • Cross linking with organic and inorganic agents
  • Shelf Life 1 year
