Business Overview
comprehensive technologies including surface treatment and
line services to provide surface treatment systems
that aim to be both environmentally and economically friendly.
- Pretreatments
- Functional coatings
Automotives and industrial fields
Feature: Environmentally friendly conversion coatings to replace zinc phosphate coatings
-
Reducing substances that place a
burden on the environmentHeavy 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 appearance (SEM) |
||
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 |
Environmental burden | Phosphate, nickel, manganese | Nothing of note |

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

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.

Functional coatings
A hydrophilic treatment type suitable for the type of heat exchanger is available
- Automobile air conditioner
-
- Post-coating
-
Hydrophilic treatment of a completed
heat exchanger - Extra features
- Anti-odor
Comfortable even in the cabin, a compact space. - Room air conditioner
-
- Pre-coating
-
Hydrophilic treatment of aluminum plates
before making heat exchangers - 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
-
- After
-
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
Heat exchange efficiency is improved and condensation clogging is mitigated.
