Powder coatings are usually done by electrostatic spray deposition (ESD) or fluidized bed application. Both methods provide great gloss, texture, variety of colors and a high quality finish, enabling them to be used in a variety industries, and can be applied to outdoor furniture. With powder coating, outdoor furniture manufacturers can enhance the functionality and durability of outdoor furniture. 

How does powder coating work?  

The powder coating process is a multi-step process. The process usually includes preparation, coating and curing stages. Powder coatings use powdered materials on a preheated substrate surface.

Pretreatment:

Cleaning and preparing the surface of the substrate is essential prior to applying any powder coating.Cleaning and blasting furniture can strengthen the powder coat’s bond to the metal surface. Blasting uses abrasives to remove previous coats or rust from furniture surfaces, while cleaning removes substances and impurities. Some metals, like steel and aluminum, might require priming before receiving coatings.

Coating: Technicians will electrically charge powder particles to apply them to the metal’s surface. 

Curing: During the curing stage, teams bake the furniture to seal the bond between the surface and apply the desired finish. Curing conditions will differ depending on the product’s material, powder thickness and size. Various products might have different curing temperatures and time requirements to ensure the best results.
