Powder coating is a specialized type that is usually referred to as paint in the form of powder. This particular type is applied as a dry and is mostly used in cases where a decorative, but hard paint finish is sought. The usually is categorized in the types of thermoset polymer and thermoplastic. The coating is usually applied via things that are enabling of holding onto electrical charge followed y a cure that is usually undertaken in a huge industrial oven at 200 degrees.

The coating is usually applied on both interior and exterior items that include fencing and architecture. Which can also be applied over galvanized steel usually, leaves an unattractive and rough finish. To receive a smoother finish, it is advisable that you choose thermal spray, an ideal alternative to galvanizing. Thermal spray ensures a uniform and flat surface that allows the coating to stick to the surface. This particular type is resistant to extreme environmental conditions.

Powder coating features several advantages that often offer it an edge over conventional paint. As said earlier, is categorized into two main types that are thermoplastic and thermosets. The thermoplastic type need not undertake any further reactions during the baking process and flows onto the final, whereas the thermosetting type reacts with other chemical group in the powder to form a polymerize effect enhancing the performance of the properties. The most used polymers in powder coating include polyurethane, straight epoxy.
