Powder coating
Introduction to Powder Coating.
There is little that can be done to change the color consistently once the powder leaves the manufacturing plant.

Thin powder coatings can be bent but this is not recommended for exterior applications. The choice of colours and finishes is almost limitless if you have the time and money to have the powder produced by the powder manufacturer. Powder coatings can be applied over a wide range of thickness.

During the fluidized bed coating a mesh is dipped in an adhesive bath dried and pre-heated. It passes into a bath with fluidized PVC or another polymer powder which acts like a liquid when air is forced through the powder bed. This covers the wire surface with powder that melts on the substrate due to the preheating of the substrate. This is followed by after-curing or after-fusion of the polymer and water cooling.

As the film cools it develops its physical properties. Nylon powder coating materials are the most commonly used thermoplastic powders. Thermoset powder coatings also melt when exposed to heat but they then chemically cross-link within themselves or with other reactive components. The cured coating then has a different chemical structure than the basic resin. Thermosetting coatings are heat-stable and unlike thermoplastic powders will not soften back to liquid phase when re-heated. Thermosetting powders are derived from four generic types of resins epoxy acrylic polyester and fluoropolymer. From these resin types several coating systems are derived.
