Powder coating is a dry finishing method of applying a decorative and protective finish to a wide range of products that are used by both industries and consumers.
Finely ground powder particles of pigment and resin are electrostatically charged and sprayed onto the products to be coated. The charged particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven.
The result is a uniform, durable, attractive finish that is substantially superior to paint finishes.
The powder coating process is environmentally friendly. Painting or liquid finishes contain volatile solvents (VOCs) that pollute. The powder coating process uses no solvents and releases negligible amounts of VOCs into the atmosphere. This saves you money as we are not required to purchase costly pollution control equipment.
Powder Coating is an attractive paint like protective finish that is long lasting, and highly resistant to chips, scratches, and fading. It provides a seamless coating from a virtually unlimited selection of colors, textures and finishes.
Powder coating is a cost effective one step process that doesn't require successive coats and long curing times. Powder particles used are a mixture of finely ground pigment and resin particles. Charged powder particles are transferred onto an electrically grounded surface. A variety of processes exist for powder application. These applications range from electrostatic spraying for thinner coatings (0.001" - 0.010") to dipping in a fluidized bed for thicker coatings (0.007" - 0.040"). During the curing process the powder is fused into a smooth coating. Depending on the process, powders are either thermal cured (convection or infrared) or UV-cured. The powders used may be either thermoplastic (same chemical composition after reflowing) or thermosetting (chemically cross-linked with themselves or other reactive components).
Powder coating has been used on metal surfaces for over 40 years. Recent advancements have expanded its use into ceramic, plastic (nylon and polycarbonate) and MDF (medium density fiberboard) applications.
