TCI Powder Coatings Blog

The process of manufacturing powder coatings is a relatively complex process that must be carefully controlled to ensure a high-quality final product.  Powder coatings are manufactured in a multi-step process of pre-mixing, extrusion, and micronization.  Basically, materials are blended, melted, cooled, and then pulverized. This blog will focus on micronizing, the last step in the process.  Micronizing Process:  the powder chips are fed into a grinding machine, which breaks the chips down into a fine powder.  The powder is then filtered to ensure that no large particles contaminate the powder.  For more information from TCI Powder Coatings on the manufacturing of powder coatings, please refer to our TroubleshootingGuide or contact us today to speak with our experienced team about how we can help you with your powder coating needs.

This blog will focus on extrusion, the second step in the process.  Extrusion Process:  this involves the powder being heated up, which activates the resin and hardeners.  The consistency of the powder is changed to a liquid, which is then cooled and hardens into a sheet.  This sheet is then broken up into small chips.  For more information from TCI Powder Coatings on the manufacturing of powder coatings, please refer to our TroubleshootingGuide or contact us today to speak with our experienced team about how we can help you with your powder coating needs.

Powder coatings are applied as a free-flowing, dry powder and are typically applied electrostatically then cured under heat to form a “skin” or hard finish that is tougher than conventional paint.  Common Uses For Powder Coatings: Around the Kitchen: Washer/dryer shells and motor casings, refrigerators, refrigerator shelving and motor casings, faucets, sinks and small appliances.   Outside the House: Lawn and garden tools, mowers, edgers, and patio furniture. In the Workplace: Computer hardware, office furniture, filing cabinets, storage and display shelves, warehouse racks, and lighting fixtures. Heavy Equipment: Agricultural mowers, irrigation equipment, tillers, and construction equipment. Building Products: Rebar and steel cable, columns, water treatment facilities, HVAC units, gas  and oil transmission lines, windows, sliding doors, canopies, and architectural decoration. Transportation equipment: Truck and trailer...

Dry coatings can be dated back to 1000 B. C., with porcelain and other vitreous enamels among the earliest of dry coatings.  Porcelain was used extensively on cast iron in the mid 19 th century.  By the 1950s, the first organic coating, thermoplastic vinyl, was being applied with a fluidized bed.  A German scientist, Dr. Erwin Gemmer, developed the fluidized bed application for thermoplastic resins on metal as a more productive alternative to flame spraying, in which melted (or heated) materials are sprayed onto a surface. From 1958 to 1965, almost all powder coatings were applied with the fluidized bed process.  The thick applications were primarily used for electrical instillation, as well as abrasion and corrosion resistant purposes.  The technology and application methods of powder coatings continued to evolve when France introduced the first commercial application of epoxies in 1962 and in 1968 when spray applications appear in Europe. ...

Powder coating is a dry finishing process that has become extremely popular in the industrial finishing market, and is used on a wide array of products. More and more companies specify powder coatings for a high quality, durable finish, allowing for maximized production, improved efficiencies, and simplified environmental compliance.  Used as protective and decorative finishes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties.   So what's in a powder coating? Resin – either polyester or epoxy. Curing agen ts – added to bind the coating.  For polyesters, primid curing agents are used.  For epoxies, dicyandiamide curing agents are used. Additives – give the powder a desired effect. Tint pigments – there are two types: inorganic, which are generally pale and dull; and organic, which are more brightly colored. TCI Powder Coatings pr...
