Powder coatings are widely used by manufacturers as a finish of choice to enhance the appearance and performance of their products. This article begins with a discussion on advantages and disadvantages of powder coatings. It describes the selection of coating-types and uses of powder coatings in appliance industries, furniture industries, computer industries, fixture industries, architectural industries, automotive industries, agriculture and construction equipment industries, recreational equipment industries, and general industries. Powder coating formulations consist of binder systems, pigments, extenders, and additives. The basic process flow for the manufacture of powder coatings consists of premix, extrusion, grinding, and packing. The article also provides information on application of powder coatings, including pretreatment, deposition, and curing as well as on troubleshooting, trends and challenges for the powder coatings.

Functional fusion-bonded epoxy (FBE) coatings are used as external pipe coatings, base layer for three-layer pipe-coating systems, internal pipe linings, and corrosion coatings for concrete reinforcing steel (rebar). This article provides information on the chemistries of FBE, and discusses the application procedures for internal and external FBE pipe coating. The procedures involve pipe inspection, surface preparation, heating, powder application, curing, cooling, coating inspection, and repairing. It describes the problems and solutions for FBE external pipe coatings, girth weld FBE application, FBE custom coatings, internal FBE pipe linings, and FBE rebar coatings.

Metal powders are used as fuels in solid propellants, fillers in various materials, such as polymers or other binder systems, and for material substitution. They are also used in food enrichment, environmental remediation market, and magnetic, electrical, and medical application areas. This article reviews some of the diverse and emerging applications of ferrous and nonferrous powders. It also discusses the functions of copier powders and the processes used frequently for copier powder coating.

This article provides background information on the chemistry, coating properties, resin types, applications techniques, and performance characteristics of fluoroethylene vinyl ether (FEVE) resins. It describes the formulation methods of FEVE resins, namely, solvent-based coating formulations, water-based coating formulations, and powder coating formulations. The basic concerns to be addressed when formulating and using FEVE coatings are also discussed. The article concludes with a section on health and related safety regulations.
