SPCI stocks a large variety of hanging fixtures to maximize production output. The coating method is made up of a micronized powder coating applied using a spray gun, whereby the powder is drawn to a grounded element through an induced electrostatic charge. Epoxy-based powder coatings have been used on gas and oil pipelines since the early 1960s and some of them are still in service today. This approach provides the best possible even dispersion of a small amount of a catalyst over the bulk of the powder. The epoxy powder gradually fuses to form a homogenous coating. With liquid paint, horizontal and vertical painted surfaces often have differences in appearances, but powder coating typically provides a uniform visual appearance regardless of orientation. This process begins when powder coatings particles are charged in a powder coating gun and the target part is attached to an electrically grounded fixture. The fusion-bond epoxy powder coating was introduced as in the 60’s and there are modern types of the method available now. The process of the coating is like this :the powder is fluidized in the powder hopper. Advanced hybrid systems for indoor applications are established to cure at a temperature level of 125-130 °C (257-266 °F) preferably for applications on medium density fiberboards (MDF); outdoor durable powders with triglycidyl isocyanurate (TGIC) as hardener can operate at a similar temperature level, whereas TGIC-free systems with β-hydroxy alkylamides as curing agents are limited to approx. 3.

Type of coating applied as a free-flowing, dry powder. Parts made with a thinner-gauge material need to be burned off at a lower temperature to prevent the material from warping. The type of nozzle used will depend on the shape of the workpiece to be painted and the consistency of the paint. The differentiating factor of this process from others is the separation of the melt stage before the cure stage. The curing schedule could vary according to the manufacturer's specifications. Subsequent surface treatments might include blasting, if required, a… The powder coating process was invented around 1945 by Daniel Gustin and received US Patent 2538562 in 1945. For applications in general metal industry it is important to provide suitable performances for all gloss levels in all colors. Some heat sensitive plastics and composites have low surface tensions and plasma treating can be necessary to improve powder adhesion. Hybrids perform well in … %%EOF Enamel - based coatings The innovative mixing method used to homogenize the nanoparticles in the matrix was a hot mixer. 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. The thermoplastic variety does not undergo any additional actions during the baking process as it flows to form the final coating. endstream endobj 15 0 obj <>>>/Filter/Standard/Length 128/O(� �R�U@������8����~�� ����X�)/P -1052/R 4/StmF/StdCF/StrF/StdCF/U(�1�c��Ȅ��5G�J )/V 4>> endobj 16 0 obj <>/OCProperties<>/OCGs[41 0 R 42 0 R 43 0 R 44 0 R 45 0 R 46 0 R 47 0 R]>>/Outlines 7 0 R/Pages 12 0 R/Type/Catalog>> endobj 17 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/ImageC/Text]/Properties<>/XObject<>>>/Rotate 0/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 18 0 obj <>stream In this case, the powder picks up a positive charge while rubbing along the wall of a Teflon tube inside the barrel of the gun. The powder coating process is a dry painting process that is mainly used for coating metal. [3] For such powder coatings, film build-ups of greater than 50 μ (Microns) may be required to obtain an acceptably smooth film. ABOUT J. K. POWDER PAINTS Our core competencies shall be Epoxy and Pure Polyester coating for industry specific applications. Coating Valve bodies are removed from the oven once 410°F has been reached and hung on the painting system. The process takes about four hours and requires the parts to be cleaned completely and re-powder coated. Most powder coatings have a particle size in the range of 2 to 50 μ (Microns), a softening temperature Tg around 80 °C, a melting temperature around 150 °C, and are cured at around 200 °C. For special applications like coil coatings or clear coats it is common to use glycidylesters as hardener component, their cross-linking is based on the carboxy-epoxy chemistry too. Epoxy powder coating has good electrostatic charging properties and excellent transfer efficiency. Typical epoxy-based fluid bed powder coating application temperatures range from 180 degrees Celsius to 250 … Powder Coatings: 1. The parts are not preheated as they are for the conventional fluidized bed dip process. Epoxy Prime. It is also common to heat the metal first and then spray the powder onto the hot substrate. During the coating operation, the valve bodies are rotated to ensure the symmetrical coating thickness. The wear resistance of organic coatings is a key factor in preserving their barrier effect against corrosion. CST epoxy coated tanks using the OptiBond process are becoming the standard for epoxy durability, corrosion resistance, UV breakdown, and abrasion. The result is a hydrophilic, wettable surface that is amenable to coating flow and adhesion. Including the epoxy hybrids, epoxy powder coatings comprised over 50% of the thermosetting powder coating market by the early 1990s. Low bake powder coating resins alternatively allow the formulation of so-called fast cure powders curing at 180 °C (356 °F) for 2 minutes providing increased productivity as a target. 160 °C (320 °F).
