Metallic Powder Coating process – Problem and Solution

Metallic Powder Coating Systems Special Effects

Metallic powder coatings are decorative finishes for metal finishing applications. The multi-coloured metallic powders are often implemented with application only, and so is top coated with clear powder to improve the finish even more.

metallic and mica powder coatings contain metal flake or particulate material mica that gives these finishes its special appearance. These flakes and indications are a stand-alone component. Metallic and mica powder coatings are evenly mixed with a powder base colour and are referred to as mixed dry powders. They are available in epoxy, Hybrid, urethane, and TGIC polyester chemical.

The problems faced with dry powders are mixed with color consistency, limited penetration in recessed areas, and its limited ability to be recycled. Mixed dry powders are usually applied using a Crown, with a flat jet nozzle. Metallic coatings and mica powder are processed by physically linking them to the surface moved. Generally, all metallic or mica particles is connected, However, some cannot be firmly fixed and can cause various problems in the process of finishing.

Metallic powder and mica Bonded has fewer lines than the powders mixed with dry and are more easily recyclable. Furthermore, They also provide color that is more recycling and less consistent effect picture frame, as well as a better penetration and higher transfer efficiency. Even if connected and metallic mica powder can be recovered, It is always better to minimize dust ration recovered Virgin powder so that you will produce the best possible finish. Customs post are available in epoxy, Hybrid, urethane, and TGIC polyester chemical.

metal powders have some disadvantages associated with them. The first is that aluminized powder finishes have a tendency to look weathered with time. Another drawback is loading, What is an uncontrollable loss of high voltage electrostatic power at the tip of the spray gun and occurs because the metallic powder has created a dirt road through the hose to the high voltage to travel. To reduce the load, a specially designed spray pipe can be used if the amount of powdered metal is not excessive.

The use of metallic powder has been the cause of several fires of spray booth. Spice powder coatings are unique blends of various colors in finished powder, resulting in a highly aesthetic and protective coating. These multi-colored powders are available in Epoxy chemicals, hybrids, urethane, and TGIC polyester. Powder coating of spices are most often used for end use applications, such as casual furniture, shelves, case goods, and leisure equipment. However, powder coating of spices can be used for other items.

powder coating Spice do represent some challenges to the applicator when compared with use and smooth application, solid color powders. So, applicators must apply a consistent pattern and even to ensure consistency film thickness and produce a quality appearance. Due to the nature of the powder coating of spices, the appearance of color and can vary when the powder is recovered. Furthermore, the density of the substrate can affect the flow and appearance of the finished product

Tips on how to SPRAY metallic powders. –

Since metallic powder is made by the addition of finely ground pure mica or aluminum or bronze particles, you are, actually, spraying a mixture of both plastic and Aluminum powder in fine powder mixed with it. With the different weapons metallic particles in relation to the subject of soil can focus differently. The orientation of the aluminum particles will determine the final finish.

1. Reduce the dosage, as low as possible for a smooth soft stream.

2. Preferably, use Stick or gravity glass so that the airflow of Fluidization not disturb the particle size distribution. 3. Increase the distance between gun and object of at least 8 inches or more.

4. Try with different nozzle nozzle especially soft.

5. Make sure that the powder coating material is placed in front of an oven temperature of 200 ° C —- If the oven will be at room temperature, the coating will flow to 150 ° and disturb the texture creating a smooth finish.
