Epoxy powder coatings were originally used for functional (protective) markets, but they are now used for decorative markets as well. The innovative mixing method used to homogenize the nanoparticles in the matrix was a hot mixer. %%EOF Because powder coating does not have a liquid carrier, it can produce thicker coatings than conventional liquid coatings without running or sagging, and powder coating produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces. The most commonly used method is spraying electrostatically charged particles of pigment and resin onto an electrically grounded piece. Fusion Bonded Epoxy coatings. ABOUT J. K. POWDER PAINTS Our core competencies shall be Epoxy and Pure Polyester coating for industry specific applications. Parts made with a thinner-gauge material need to be burned off at a lower temperature to prevent the material from warping. Powder coating processes vary by the type of material being applied; however, they can generally be divided into four functions: 1. The powder coating process involves three basic steps: part preparation or the pre-treatment, the powder application, and curing. Whether you’re new to powder coatings or an experienced pro, you’re probably well aware that powder coating is a fantastic painting method that creates a tough, durable and beautiful finish. CST epoxy coated tanks using the OptiBond process are becoming the standard for epoxy durability, corrosion resistance, UV breakdown, and abrasion.
