There are many types of durable powder coating applications that can shield steel and other types of metal on the debilitating effects of corrosion. Many manufacturers keenly understand the degrading and destructive nature of corrosion on metals. Fortunately, commercial distributors offer powerful coating products to protect parts and components of machinery and equipment. A widely popular metal finish used in the United States is polyester powder coating.
Thermoplastic and Thermoset Coatings
Thermoset and thermoplastic are the two major types of powder coating applications. Thermosetting coatings have heat stability and do not return back to liquid state when reheated. These powders come from four different generic types of resins, including fluoropolymer, polyester, acrylic, and epoxy. Thermoset powder coatings, for instance polyester, Mel when subjected to heat. Subsequently they can become chemically cross-linked or mixed with other reactive components. When the final cured coating is achieved it possesses a different chemical structure from the basic resin.
Polyester powder coating utilizes varying chemical combinations for the production of various products, including polyester/TGIC-free, polyester/TGIC, polyester hybrids, and super-durable polyester. This type of powder coating finish accounts for 60 percent of the market in the U.S.
Application to Metal Surfaces
These coatings are manufactured for metal finishes. Subject to the formulation of the coatings, they can be used on steel that has been cleaned and phosphatides. An air assisted electrostatic powder spray gun is used to apply the coating to metal surfaces – this includes a uniform dry film coating to achieve excellent surface coverage. A curing process takes place. As well, colors are coordinated between batches quite easily.
Cost Efficient
The various industries that utilize polyester powder coating include HVAC, construction, automotive, railways, agricultural farming, and household appliances. These coatings do not depend on a chemical solvent in their formulation. This results in a product with less toxicity on the assembly line for workers. In addition, it minimizes the costs associated with safety compliance issues and the required disposal of chemical solvents.
If you need to obtain the services of a reliable coatings and metal plating supplier, evaluate a company’s years of experience and track record in the industry. References of past customers can help you verify the nature of the company’s services and products.
