PROTECTIVE ADHESIVE FILMS
Themetals industry isunder increasingpressure toproducehighqualityproductsat lowerprices.Thishas resulted in theuseof technologicallyadvancedproductionmachinery to increaseproductivity.Thetechnology involved in protective films has had to keep pace with these changing demands. We have a variety of protective adhesive films are available to meet the various demands of the metals industries.
Applications - Deep Drawing, Laser Cutting, Turrett Punching, Pressing, Roll forming, Storage,Transportation,etc,.
Material types - Stainlesssteel,aluminium,copper,brass,pre-paintedsteels.
We can supply protective film in rolls for you to apply as required, or we can apply them to sheet in our local servicecentres.
Please contact Corus Metals to discuss the most appropriate film and application method for your end use. Testingmayberequiredpriortocommencingproductionruns.
DIE-COVER FILM
Die-Cover film is a proven and economical way to prevent die marks when using a press brake to form Stainless Steel, Aluminium, pre-finished or painted metals. Film life will vary with a number of factors such asthethicknessofthemetalbeingformed,thetypeofmetal,andtheseverityofthebend.Whilesomecustomers forming light gauge aluminium are getting several hundred bends on a single piece of film, othersformingheavygaugestainlesssteelmaygetonlyafewbends.

Analloyconsistsofahomogeneousmixtureof twoormoreelements,ofwhichat leastone isametalandall theresultingphaseshavemetallicproperties.Thehighalloystainlesssteelsareusuallychosenasstructuralmaterialsbecauseoftheircorrosionresistanceandattractivesurfacefinishandbecausetheyrequireminimummaintenanceinoperation.Thesepropertiesofthestainlessalloysareintimatelyrelated,becausethesurfaceofastainlesssteeliscoveredwithavery thin, tenacious filmofchromiumoxidewhich“passivates” themetalsurface,giving to it the“stainless”qualities. Ifmechanicallydamaged, the filmwill reform(i.e. re-passivate) in thepresenceofoxygen,orotheroxidants,aslongasthechromiumcontentexceedsabout12%.
Although passive oxide films on metals and alloys give excellent protection against corrosion, they have thedisadvantage that a change in the service conditions can lead to destruction of the protective oxide film andconsequentlytorapidgeneralorlocalisedcorrosion.Inthisconditionthealloyissaidtobe“active”anditmaysufferfromarateofcorrosiveattackcomparablewiththatforplainmildsteel.Thisrelativelyrareproblemmaybeovercomebycarefulselectionofagradeofstainlesssteelwhichismorecorrosion-resistantbecauseoftheadditionofalloyingelementssuchasmolybdenum,copper,titaniumandniobium.
Corrosion problems encountered with stainless steels

(1) Extended exposure at high temperatures can result in embrittlement of austenitic stainless steels, or in“sensitisation” which diminishes the ability of the alloy to withstand corrosion, particularly in acid-chloride conditions.
(2) Thermal cycling,particularlyinthepresenceofmoisture andcondensation, hasadeleteriouseffectonsomestainlesssteels.Ferritic steelsare lessaffectedby thisproblem thanareaustenitics, owing toa lower co-efficientofthermal expansion.

Hydrochloric acidshouldnotbeusedforthispurposeaschlorideshaveadeleteriouseffectonthepassivefilm,whichcanleadtolocalisedpitting.

Crevice corrosion
This formofcorrosiveattackconcentrates innarrowfissureswhereoxygen access ispoor.
