Feature: Environmentally friendly conversion coatings to replace zinc phosphate coatings
  • Reducing substances that place a
    burden on the environment

    Heavy metals, conversion sludge

  • Shorter process

    Cost reduction, time reduction

  • Superior corrosion resistance

    Long-term rust inhibition

Difference in coating properties
Conventional zinc phosphate conversion process Zirconium conversion treatment

Coating structure Metal phosphate crystal coating Amorphous metal oxide film
Adhesion Anchor effect between the formed crystalline coating and the applied coating Chemical bond with the applied coating resin due to the introduction of an adhesive functional film
Corrosion resistance Alkaline buffer / self-repair A fine structure with low porosity that is less prone to permeation by corrosive substances
Coating weight 1.0-2.0g/m2 0.05-0.10g/m2
Process before conversion Activation process is required Not required

Treatments for aluminum beverage cans

Aluminum is very susceptible to oxidization. The following is required to use it as a container for beverages.

  • Removal of
    oxidized layer (rust)
  • Removal of grime deposited
    during forming
  • Prevention of reoxidation
    after rinsing
Summary of the aluminum beverage can
treatment process
  • Degrease
  • Conversion
    Coatings
  • Rinse and
    drying

Functions of our chemicals
  • Degreasing agents

    The surfaces of aluminum cans after the forming process have deposits of rust and oil-based grime, and our products function to remove these.

  • Conversion agents

    Aluminum is a metal that is susceptible to corrosion. Our products function to form a metallic coating that endows the aluminum can surfaces with functions such as corrosion resistance and coating adhesion.

Extra features
Workability and soiling
Remains hydrophilic even when working fluid is deposited.
Condensation clogging is mitigated with our hydrophilic treatment
  • Before
    Condensation clog formed
    Endowed with our technology for water leakage

    Condensation clog unclogged

Prevent condensate that forms during
cooling from clogging the fins (condensation clogging)
on the heat exchanger and
decreasing cooling efficiency.

Required performance
Prevent condensation clogging between heat exchange fins
Endow it with water leakage property with our hydrophilic treatment technology.
Heat exchange efficiency is improved and condensation clogging is mitigated.
