Metal Anti-Corrosion Treatments


The annual cost of damage caused by rusting steel is thought to be equivalent to around 2-4% of GNP in Japan. The application of Anti-Corrosion treatments is therefore vital to extending the usable life of numerous metal products, including small automotive components and metal structures used to reinforce buildings against earthquakes. To this end, we supply two advanced Anti-Corrosion treatment systems: DACROTIZED® and GEOMET®.

DACROTIZEDDACROTIZED®
The target item is first dipped or sprayed with DACRODIP® solution, a water-based dispersant, before DACROTIZED® treatment is applied through a baking process. The treatment resulting from this process gives the treated part improved corrosion resistance. Further, the coating process does not result in hydrogen embrittlement, a common weakness of electroplating processes. Thanks to superior performance such as a strong resistance to heat, DACROTIZED® treatment is often specified in design standards for automobile component and other metal products in Japan and around the world. DACROTIZED® treatment is widely used in automobile components, civil engineering and architectural applications.

GEOMETGEOMET®
GEOMET®, an Anti-Corrosion treatment systems that contains no toxic substances such as lead, cadmium, mercury or chromium, is the result of 30 years of research and development into Anti-Corrosion technology. Boasting the features of DACROTIZED® treatment, GEOMET® is an environmentally friendly treatment systems. GEOMET® is often specified in design standards for automobile components both in Japan and overseas.

GEOMET PLUSGEOMET PLUS®
GEOMET PLUS® sealers are water-based topcoats used in conjunction with GEOMET® that make full use of its characteristics. Although the topcoat is only a thin layer, it is effective in stabilizing friction coefficients, preventing electrolytic corrosion, implementing blackening, and improving resistance to corrosion and chemicals.

Dry Galvanizing Treatments (ZCOAT™ + Nonchromate Treatment)


ZCOAT is a dry galvanizing treatment that differs from electric dry galvanizing and hot dip galvanizing processes. As an impact plating treatment it generates no wastewater and can be applied using lower temperatures. UNIMET® is an environmentally friendly topcoat used in conjunction with ZCOAT.

UNIMET®
UNIMET® is the water-based and non-chromate topcoat used in conjunction with ZCOAT for improving corrosion resistance remarkably.
UNIMET® GT-series can be applied to silver-color finish or black-color finish, with suitable selection.
  • silver-color finish : ZCOAT+UNIMET® GT-103
  • black-color finish : ZCOAT+UNIMET® GT-103+UNIMET® GT-506

Sealers


Sealers are vital to ensuring bolts are safely secured in place. With our water-based GEOMET PLUS® sealers, used in conjunction with the DACROMET® and GEOMET® coating systems, we offer fixed sealing films suitable for a variety of different friction coefficients.
