Powder Coating and Its Applications

Powder coating is a kind of paint spraying process that uses dry powder as a dry, powder-like product to cover steel and other materials. Unlike traditional liquid paint that is sprayed through an evaporating solvent, powder coating typically is applied electrostably and then either cured or under ultraviolet light. A powder coating finishes by hardening to a high gloss and reflecting the light for a uniform, smooth surface. This type of finish has many advantages over other types of paint, most notably its durability and resistance to cracking and peeling. This article will give you more information on powder coating and its application.

There are three basic types of powder coating cincinnati. They are thermoplastic urethane powder coatings, thermoplastics, and thermoset powder coatings. Thermoplastic urethane powder coatings are the cheapest because they are made from expanded polystyrene. Because it's easily molded into the desired shapes, it's often used for interior automobile parts. However, the material tends to expand while it cures, leading to tiny bubbles. These bubbles, called spatter, ruin the painted surface and are difficult to remove.

Thermoset powder coating cincinnati, or thermoplastic urethane powder coating, is the most common. It uses polyester resins as its active ingredient, mixed with a powdered binder (such as ethyl acetate). Although the materials used in this kind of coating tend to be somewhat stiffer than polyurethane, the end result is still flexible enough to be shaped without causing blisters. The most notable advantage of these powders is that they tend to resist UV light, so they can be used outdoors.

Many industries use liquid coatings because they give the finish a more glossy look. Because most industrial coatings contain ethylene-based compounds that tend to leave an oily residue, liquid coatings can be applied over a clean surface and then left to dry. A final buffing is required to remove the oily residue, and the final color will be consistent throughout the material.

There are two basic types of powder coating. The first is dry powder coating, which consists of a liquid base coat, a clear topcoat, and a bottom coat to seal the product. A dry powder coating requires application of the coating to a prepared metal surface by applying pressure with a pump. Typically, pressure is not needed because the coating dries quickly.

The second type is wet powder coating, which includes applications such as bumpers, tanks, shipping containers, signs, and airplane seats. In this type, a hot air compressor is used to apply the coating to the item. Like dry powder coating, a powder coating gun must be employed because it forms an oily film on the item to which it is applied. Also, as with dry powder coating, a gun must be employed because it forms an oily, water-resistant finish on the item. A spray gun is not required in wet powder coating because the product dries instantly on contact with any surface, including metal. A spray gun is only required in the case of liquids or some non-metal objects.
