NOVAMET Stainless Steel Flakes NOVAMET produces a range of bright, attractive stainless steel flakes, all manufactured from UNS - S 31603 grade stainless steel (formerly known as AISI Type 316L). This is a highly corrosion resistant grade - containing typically 18% chromium, 10% nickel, 2.5% molybdenum - that also shows excellent resistance to abrasion. It is commonly used in the chemical industry for process plant construction. This range of flakes shows excellent durability even in very aggressive environments and is therefore ideally suited to the production of 'metallic' coating systems for use in exacting situations. Five different grades are produced, all available in standardised packs.
Stainless Steel Flake Standard Leafing Grade This material shows all of the outstanding properties of the Fine Leafing Grade but has a slightly larger mean flake size of approximately 60 microns and a slightly greater flake thickness around 1.2 microns Stainless Steel Flake Fine Water Grade This is a non-leafing grade developed for use in aqueous-based systems. Stainless steel has an important inherent advantage in these formulations since it does not react with the medium to form hydrogen and produce to 'gassing'. Stainless Steel Flake Standard Water Grade This material exhibits similar properties to the Fine Water Grade. It is analogous to the Standard Leafing Grade in that the flake size and thickness are greater than the equivalent Fine Water Grade. This results in a brighter appearance. Stainless Steel Flake SSC Grade This special grade of stainless steel flake has a thickness in the region of 0.3 microns. It is used in decorative paint systems to produce an appearance resembling that of pewter thus providing a finish with a 'perception of quality'. It exhibits all of the other benefits of NOVAMET stainless steel flakes in terms of corrosion and abrasion resistance. NOVAMET Decorative Nickel Flakes The NOVAMET range of bright, decorative nickel flakes is manufactured from high purity carbonyl nickel powder. These flakes show all of the properties of nickel metal including its corrosion resistance, particularly in alkaline media, ductility and ferromagnetism. Nickel Flake Fine Leafing Grade This leafing grade product has a mean particle size around 30 microns and a typical thickness of 0.4 microns. It is suitable for the production of 'metallic' effect powder coating finishes as well as for liquid paint systems. It also exhibits a useful degree of ferromagnetism. A special pigment grade that has particularly high opacity in very thin films is now available. This shows advantages in ink systems. Nickel Flake Standard Leafing Grade This exhibits all of the properties and advantages of Nickel Fine Leafing Grade. However, it has a slightly larger mean flake size of approximately 60 microns and a slightly greater flake thickness around 1.2 microns producing brighter finishes. Nickel Flake Fine Water Grade This non-leafing variant was developed for use in water-based products where its natural stability in aqueous environments avoids the problem of gas formation. It has a similar mean particle size and flake thickness to Fine Leafing Grade and also exhibits a useful degree of ferromagnetism.
