Metallic Powder Coatings

Pearlescent Pigments Traditional pearlescent pigments consist of a high-refractive-index metal oxide layer coated onto a transparent, low-refractive-index substrate such as natural mica. This layering structure interacts with light to produce constructive and destructive interference patterns in both the reflected and transmitted light, which we see as color. This technology has been extended to other synthetic substrates such as glass, alumina, silica and synthetic mica. Various effects range from satin and pearl luster, to sparkle with high chromatic values, and hue-shiftingRead More …

The pearlescent pigment having a colorless transparent, high refractive index, the directional foil layer structure, in the light irradiation, after repeated refraction, reflection and showing a sparkling pearl luster pigment. Not any permutation of the pigment platelets can produce crystal sparkle effect, in order to form a pearl and color, a prerequisite is the state of the lamellae pearlescent pigments are parallel to each other and arranged in rows along the surface of the coating. Construction of varnishes and paints,Read More …

Bonded and non-bonded are terms usually used when referring to metallic powder coating.  All metallics used to be non-bonded, which meant that a powder base coat was manufactured and then the metal flake was mixed with the powder to create a metallic. In bonded powders, the base coat is still manufactured separately, then the powder base coat and the metallic pigment are placed in a heated mixer and heated just enough to soften the powder. As the powder is mixedRead More …

Metallic and mica powder coating contains metal flake or mica particulate matter that gives these coatings their special appearance. These flakes and particulars are a freestanding component. Metallic powder coating is homogeneously blended with a base color powder and are referred to as Dry-Blended powders. They are available in Epoxy, Hybrid, Urethane, and TGIC Polyester chemistries. The problems faced with dry-blended powder coating are with color consistency, limited penetration in recessed areas, and their limited ability to be recycled. Dry-blendedRead More …

Since metallic powder coating of this type is made by adding pure finely ground mica or aluminum or bronze particles, you are actually spraying a mix of both the plastic powder and the fine aluminum powder mixed with it. With different guns the metallic particles in relation to the ground object may orient themselves differently. The orientation of the aluminum particles will determine the final finish. Reduce dosing air, as low as possible to get a smooth soft flow. PreferablyRead More …

Aluminum for its proportion of small, easy processing, mechanical strength and other characteristics over the years is widely used in the building’s doors and windows, walls and other products. Aluminum is more lively and light metal with a silver-white luster, and the corrosion resistance of the following two characteristics: The higher the purity, the better the corrosion resistance, mainly because of pure aluminum with oxygen in the air, production in the aluminum surface a thin layer of dense natural oxideRead More …

A number of color innovations have been achieved for powder coating. Photoluminescent Photoluminescent powder coating is able to absorb ultraviolet, fluorescent, or incandescent light, and gradually re-emit the light. These are often available in blue, yellow and green, and are used for road signs, hazard warnings, and markings on trucks, buses, and police cars. Metallics Metallic coatings add sparkle highlights, which can reproduce the appearance of the base metal and add richness to the look of the product. A varietyRead More …

Bonding In 1980, a technique of metallic powder coating was introduced for adding effect pigments to powder coating. The process involves adhering the effect pigments to the powder coating particles to prevent separation during application and recycling. Following research during the 1980s and early ’90s, a new continuous multi-stage process for bonding was introduced. The main advantage with the Bonding process is the degree of control over the entire operation. Batch size becomes less of an issue and there areRead More …

Metallic finishes have a luster and brilliance that sets them apart from finishes produced by conventional pigments. For many applications, a metallic effect is highly desirable and can be achieved by adding aluminum, gold bronze or pearlescent pigments. While it is relatively easy to incorporate such pigments into liquid systems, the situation is much more difficult for powder coating. Various problems associated with the manufacture of metallic powder coatings and some solutions will be discussed. The powder coating market hasRead More …
