Flake zinc pigments

Flake zinc pigments have a barrier effect and also act by a cathodic anticorrosive mechanism. Compared with zinc dust coatings, flake zinc pigments are formulated with lower pigment volume concentrations [5.178]. [Pg.209]

Flake Zinc Pigments. Flake zinc pigments are used mainly as high-quality anticorrosive pigments in powder or paste form. Owing to their platelet structure they have a considerably higher surface area than spherical zinc dust particles. They can... [Pg.230]

The flake zinc pigments give a considerably brighter, better metallic effect than zinc dust. Their appearance can be further improved by combining them with aluminum pigments or by applying a topcoat based on aluminum pigment. [Pg.231]

Another widespread application for flake zinc pigments is the coating of small articles with complex shapes (e.g., screws, steel springs, bolts, rivets) and for special anticorrosive paints (Section 5.2.11.1). [Pg.231]

With manganese, copper, and zinc pigments, there is a risk of catalytic decomposition of polyolefins that is possibly combined with odor nuisance. Coloration with manganese flakes is still practised for articles with short lifetimes, but it tends to be replaced by more stable strontium compounds. [Pg.581]

Definition. Metal effect pigments consist of flakes or lamellae of aluminum (aluminum bronzes), copper and copper-zinc alloys ( gold bronzes ), zinc, and other metals (DIN 55943, 55944 FSO 4618-1). [Pg.228]

Copper-zinc alloys with a higher zinc content (brass) cannot be ground or formed into flake pigments on account of their brittleness. Controlled oxidation of natural bronze powders converts them into fired bronze powders. These shades (e.g., English green, lemon, ducat gold, fire red) are produced as a result of interference effects that depend on the thickness of the oxide coating. [Pg.230]

Zinc oxide has a wide range of uses apart from its use as an artist s pigment where it provides a more translucent white than flake white or titanium white. It is used in cosmetics, driers, quick-setting cements with syrupy phosphoric acid or zinc chloride in dental cement in the manufacture of opaque glass, enamels, car tyres, white glue, matches, white printing inks and porcelain. The photophysics of zinc oxide has been reviewed.1468 ... [Pg.998]

Metallic Pigments, The leading metallic pigment is zinc dnst, which is used mostly in zinc-rich primers, where it acts as a passivating agent. Aluminum flake is used for the silvery metallic appearance that it imparts. [Pg.1198]

Metallic Pigments. These pigments are metal flakes of various sizes made up of aluminum, copper, zinc, and/or their alloys. The aluminum flakes develop the silver metallic colors, whereas the copper, zinc, and aluminum alloys produce the gold, copper, brass, and bronze colors. The metal effect is modified, not only by shape and size, but also by perticle size distribution within a given product. Since aluminum, in particular, as a fine dry powder, can form explosive mixtures with air, most of these materials are commercially available in paste or liquid concentrates. In addition, surface treatments of these materials enhance their appearance and performance. Flakes of other metals, such as stainless steel, are used for surface protection purposes such as corrosion resistance and electrical conductivity. [Pg.97]

Zinc as a pigment for application in protective coatings is also available in the form of zinc flakes with a lamellar particle shape. Zinc flakes are mainly used in so-called... [Pg.226]

Metal effect pigments are flake-shaped metallic particles supplied in the form of powders, pastes, pellets, suspensions or color concentrates [5.166-5.168]. Typical metal effect pigments include aluminum ( silver bronze ) and copper- and copper/zinc-alloys ( gold bronze ). [Pg.252]

Heat-resistant coatings have silicone-resin binders. Pigments for such paints are zinc dust, flakes of aluminum or stainless steel, titanium dioxide, or silicon carbide. Such paints can withstand temperatures up to 600 " C. [Pg.245]

Metallic pigment n. Particles or flakes of non-oxidized metals or alloys used as pigments to modify the optical characteristics of a paint, to hide the substrate, modify the color or adjust other properties. The metals most commonly used as aluminum, bronze, and zinc. [Pg.607]
