MacDermid Enthone finishes for appliance components can be found on both the inner workings and outer surfaces of many devices that are staples of today’s society, helping to maintain the dependability and visual appeal of those products.
Our versatile, corrosion-resistant coatings can be applied to a wide range of metal and plastic substrates, such as zinc, nickel, copper, chrome and hex-chrome-free alternatives. Fashion finishes include antique/dark, bright and satin options. PFOS-free mist suppressants and hex-chrome-free processes are among our environmentally sound alternatives that provide high functionality and cost-effective solutions.
- Anodizing and conversion coatings to protect and aid paint adhesion for aluminum components
- Chromium plating for the decorative trim
- Electroless nickel is the perfect choice for parts which provide electrical conductivity
- Phosphate coatings to prepare the steel base metals for subsequent organic finishes
- Zinc based electroplated finishes to provide sacrificial corrosion protection for fasteners
Aluminum conversion coatings
Iridite NCP, EXP and 14-2 provide excellent corrosion resistance to the aluminum alloy. These coatings can be applied as the final finish or as a primer to improve paint adhesion. Typical applications could include interior and exterior surfaces of an airplane body and mechanical components used in landing gear.
Where magnesium is used, Iridite 15 is the recommended conversion coating.
These products are specified by companies such as AMS, American Airlines, Boeing, General Dynamics, McDonnell Douglas and Pratt & Whitney.
In areas of high use, for example fascia surrounds, handles and buttons, our fashion finish portfolio provides the perfect solution to enhancing component durability and aesthetics.
Designers have the option to choose from mirror bright chromium to dark satin, or our contemporary full hue colors sold as yellow, red and blue. The chromium coated finishes meet ISO 4525 for service conditions 1 and 2.
Phosphate coatings are extensively used to improve the adhesion of organic coatings to ferrous metals. The CanPhos and Keykote phosphating improves this adhesion in either spray or immersion applications.
To meet RoHS, WEEE and EOLV directives, our processes include Qualicoat and GSB approved chromium-free systems. For multi-metal use we have cleaner phosphate systems which can be teamed with high-performance dry in place final seals to provide reliable, cost-effective pre-treatment for painting.
Our latest technology BlueKote 2000 answers industry concerns on disposal of phosphates. BlueKote 2000 is both phosphate and heavy metal-free. BlueKote 2000 increases the bonding between metal and paint as well as improving the corrosion resistance. Return to top
These deposits may contain up to 13% Phosphorus by weight and unlike normal electroplating processes, they are produced without any externally applied electric current.
The coatings are applied to a wide variety of substrates with both simple and complex geometries. Electroless nickel improves characteristics such as appearance, electrical conductivity, corrosion and wear resistance.
Zinc, coupled with a trivalent chromium passivate, provides an exceptionally corrosion resistant and electrically conductive finish at an economical cost. The protection is largely the result of the zinc corroding preferentially to the steel, therefore extending component life.
MacDermid Enthone’s range of TriPass ELV trivalent passivates are all hexavalent chromium-free. Additionally the new TriPass ELV 7000 range include hexavalent chromium and cobalt-free systems.The zinc plated deposit can also be passivated to produce a black finish where required.
