METALS The Corus Group UK Ltd., London, a maker of prefinished metals, is no exception. Before releasing its newest product, the Motiva GS, the material was subjected to extensive testing, including salt spray and humidity testing, pencil hardness, and abrasion testing, testing for stain resistance and more. The company’s Motiva GS is a high-gloss, glass-effect product that has been formulated to create a unique finish together with excellent scratch, mar and corrosion resistance, says Mark Owens, Consumer Products Project Manager for Corus. The standard gloss level of Motiva GS is 100 percent, at a 60 Deg line of sight angle, but custom gloss levels are available depending on customer requirements and the end-use application. The Motiva GS range is currently available in four colors, including Strong Red, Strong Blue, Weak Green and Bronze. The Motiva family of products is specifically formulated for appliances and can be used for wraparounds, tops, doors and side panels on clothes washers, refrigerators, dishwashers, tumble dryers, and many others. Owens says that the Motiva GS comes as a co-laminate finish, while other Motiva products are available in paint, laminate and co-laminate finishes. The co-laminated steel is a pre-finished strip steel product with a number of adhesive paint layers and treatments and a PET film bonded topcoat that is applied to the top surface and a number of paint layers and treatments applied to the bottom surface. The prefinished strip steel The glass-effect look of Corus’ new Motiva GS high gloss product, which comes in a variety of colors. product features a number of paint layers and treatments applied to both top and bottom surfaces. The laminated steel is a pre-finished strip steel product with treatment and adhesive paint layers and a polymer film topcoat applied to the top surface. The polymer film may be single or multilayered. A paint layer and treatment may be applied to the bottom surface. Owens says that a range of substrates can be used including aluminum alloys, stainless steel, cold rolled steel, hot dipped galvanized steel, and Galvatite, a Corus hot-dip galvanized steel product that is available with either a pure zinc coating or an iron-zinc alloy coating. The choice of substrate depends on the application, but the most often used substrate is CR and hotdipped galvanized. Some of the production techniques that the material can undergo include shearing, blanking, press braking, bending and folding, roll forming and deep drawing and spinning without affecting the surface finish. The extent to how far it can be fabricated depends on the grade of steel used for the substrate. The grade of steel selected dictates what can and cannot be achieved in terms of the formability. An area with a deeper drawing requirement such as a clothes washer door would need a softer grade of steel than a basic wrap-around. The new products from Corus, Clad-Rex, Sandvik and ThyssenKrupp, represent just a sampling of the ever-expanding range of prefinished metal products available to appliance manufacturers. As research and development continues in this area, OEMs will have even more ways to design unique and eye-catching appliances.  For more information, enter numbers: Clad-Rex Inc . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 305 Or email: gliebrock@cladrex.com Corus Group . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 306 Or email: Mark.T.Owens@corusgroup.com Sandvik Materials Technology. . . . . . . . . . . . . . . . 307 Or email: christina.berardi@sandvik.com ThyssenKrupp Steel. . . . . . . . . . . . . . . . . . . . . . . 308 Or email: bernd.overmaat@thyssenkrupp.com www.applianceDESIGN.com The Decorex material from Sandvik comes in a variety of gloss levels. 46 applianceDESIGN March 2008 http://www.appliancedesign.com
