Powder Coating: Customization and Protection for your Enclosure

Powder Coating is a free-flowing, dry powder that is applied to metal to provide a high-quality and chemical-resistant finish.  When the coating is exposed to heat, the plastic particles melt to form a high-durability film.  Nema Enclosures offers in-house powder coating in a wide range of colors, with an excellent color match system, to meet all of your customization needs.

Thermoset powders make up the majority of powders used in industry for a wide variety of decorative and protective applications; this is due to the nature of thermosets versus thermoplastics.  Thermosets—once cured and cross-linked—will not melt and flow again if subjected to heat a second time.  Thermoplastics, however, will continue to melt and flow repeatedly if exposed to heat.

The basic types of resins used in the formation of thermosetting powders are:  epoxy, polyester, and acrylic.  Here at Nema Enclosures, we utilize a thermoset TGIC polyester blend to coat our enclosures.  TGIC polyester coatings utilize the epoxy functional cross-linker triglycidyl isocyanurate (TGIC) to create a very durable film with excellent weathering.

The powder, unlike conventional liquid paint, does not require a solvent to keep the binder and filler parts in a liquid suspension form.  Powders can be formulated to meet a wide variety of appearance or performance characteristics; this includes film thickness, gloss, texture, color, and the performance  (hardness, chemical resistance, U.V. resistance, etc.) of the coating.  Powders are composed of several different components, blended together at high speed to form the final product.  Once blended, the mixture is extruded, cooled, and then chipped into pieces.  These chips are then ground to a very specific particle size distribution, depending on the application, and screened to ensure larger chips do not pass through.

Powder coating is applied over the surface of the metal in a uniform pattern; in order for the particles to adhere to the material, they must first pass through a charging field supplied by the delivery system.  The charged particles are then attracted to the grounded metal via a clamp.  The powder is attracted to microscopic “ridges” in the grain boundaries, and settles in between these ridges.

Once the powder has been applied to the enclosure, we place the coated enclosure in our oven and allow it to melt.  Once the particles begin to melt, they flow out and chemically react to form a higher molecular weight polymer in a network-like structure.  This curing process, called cross-linking, requires a certain degree of temperature and a certain length of time in order to reach full cure and establish the desired film properties the powder was designed for.

IP54 Waterproof Test Chamber includes 2 test chamber, which are IPX4 waterproof test chamber and IP5X dustproof test chambers. LIB Industry provides various modes for choose.

The pollution of external factors is a great hazard to life and property. With IP54 grade(IP54 Test Chamber), the product can protect from proper amount of dust and water sprayed from all directions.
