Powder coating is a dry finishing process used for protective and decorative surfaces, including kettlebells. Resin, pigments, curing agents and additives are mixed, cooled and ground into a fine powder.
How it works
In electrostatic spray deposition, charged powder particles are attracted to a grounded metal part. The coated part then enters a curing oven, where heat creates long, cross-linked molecular chains. Powder can also be applied through a fluidised-bed process to preheated parts.
The cured finish is resistant to impact, moisture, chemicals, ultraviolet light, scratches, chipping and corrosion. It is available in many colours and textures and can provide a durable alternative to liquid paint.
