Production stages:Įlectrostatic spray application Powder particles are charged and attracted to the earthed object which is to b e coated.Ĭorona powder particles are negatively charged Pigments – organic or inorganic material that provides colour to the t he finished coating.Īdditives – often minor components used to tailor specific properties such as flow, gloss or texture. They provide the powder coatings’ mechanical, chemical and outdoor properties along with corrosion resistance.įiller – inorganic materials which enhances properties such as abrasion and corrosion resistance and hardness. Resin and curing agent – components that cure to form a coating film also called the Binder. What are the basic components of powder coatings? Thermoplastic – simply melts and re-solidifies the binding polymer during the film formation and does not undergo a chemical reaction during the baking process but rather flows out into the final coating. Thermosetting – undergoes a chemical reaction during cure improving the performance properties.
