High strength steel

Corrosion protection of steel is an important feature to maintain functionality in demanding applications. Our Anti-corrosion coatings provide a uniform black/silver appearance, modify friction / conductivity characteristics as well as improving abrasion resistance and paint adhesion.



The polymers that are being used for decorative trim, electronic components, displays and in-mold electronics are modified to provide; style, individuality, functionality, value, and reliability in various automotive applications. Our surface coatings are applied to plastics to improve aesthetics, haptic feel, and durability.



Aluminum is used in Chassis, battery packs, thermal management systems, powertrain, interior and exterior parts. For many automotive applications the performance needs to be further enhanced using various surface technologies.

About surface coatings used in reducing vehicle weight

Aluminum surface treatments

Aluminum in vehicles needs protecting. It also needs coatings which improve paint adhesion. These coatings must provide both corrosion resistance and meet organic coating adhesion tests. They must also be free of hexavalent chromium.

Our  Iridite conversion coatings and Oxidite anodizing products are proven over many years. They are all chromium-free.

Plating on Plastics (POP)

Describes the electroplating of decorative metals onto ABS* based plastic.

First the ABS need is metalized. This achieved by etching the surface. Then coating the roughened surface with traces of a precious metal. This process provides 'seeds' for depositing the copper, nickel and chromium layers.

Coatings for high strength steels

High strength steel needs coatings to provide corrosion resistance. On threaded fasteners they should meet predefined coefficient of friction ranges. Being high strength, coatings should also prevent the risk of hydrogen embrittlement.

For example, ZinKlad 1000 coatings have a high a surface hardness of 500 HVN. This makes them ideal for self-thread cutting threads, as they will not be removed on assembly.
