Metallic powder coatings are decorative protective finishes for Zinc Flake Coating. The multi-colored metallic powders are usually applied with single application, and then its top-coated with clear powder to enhance the finish much more.
Metallic and mica powder coatings contain metal flake or mica particulate matter that gives these coatings their special appearance. These flakes and particulars really are a freestanding component. Metallic and mica powder coatings are homogeneously combined with basics color powder and they are called Dry-Blended powders. One can choose from Epoxy, Hybrid, Urethane, and TGIC Polyester chemistries.
The difficulties faced with dry-blended powders are with color consistency, limited penetration in recessed areas, as well as their limited capability to be recycled. Dry-blended powders are often applied utilizing a corona gun having a flat spray nozzle. Metallic and mica powder coatings are processed by physically bonding these to the top of the powered coating. Generally, each of the metallic or mica particles are bonded, however some will not be firmly attached and may cause various problems within the finishing process.
Bonded metallic and mica powder has fewer lines than dry blended powders and so are more readily recyclable. Furthermore, additionally they provide color which is more consistent after recycling and fewer picture frame effect, and also a better penetration and higher transfer efficiency. Although bonded metallic and mica powder might be reclaimed, it will always be wise to minimize the ration of reclaimed powder to virgin powder so that you will produce the very best finish. Bonded powders can be bought in Epoxy, Hybrid, Urethane, and TGIC polyester chemistries.
Metallic powders may have some drawbacks related to them. The initial being that aluminized powder finishes do are likely to look weathered with time. Another drawback is loading, which happens to be an uncontrollable loss of electrostatic high-voltage power in the tip in the spray gun and occurs as the metallic powder has generated a ground path throughout the powder hose for the high voltage to travel. To minimize loading, a specifically created spray muzzle works extremely well if the quantity of Coating equipments in the powder is not excessive.
Using metallic powder is the reason behind several spray booth fires. Spice powder coatings are unique blends of multiple finished powder colors, creating a highly aesthetic and protective coating. These multi-colored powders can be purchased in Epoxy, Hybrid, Urethane, and TGIC Polyester chemistries. Spice powder coatings are generally utilized for end use applications including casual furniture, shelving, case goods, and leisure equipment. However, spice powder dacronet can be used other items.
Spice powder coatings do pose some challenges for that applicator if compared to the use and implementation of smooth, solid color powders. Therefore, applicators need to use a consistent and in many cases pattern to guarantee film thickness consistency and provide a quality appearance. As a result of nature from the spice powder coatings, the hue and look can vary greatly once the powder is reclaimed. In addition, substrate density can affect flow and appearance in the finished product.
Since metallic powder of this type is made with the addition of pure finely ground mica or aluminum or bronze particles, you are actually spraying a mix of both the plastic powder along with the Dacromet coating together with it. With various guns the metallic particles with regards to the soil object may orient themselves differently. The orientation of your aluminum particles determines the ultimate finish.
