Powder coating can also be removed by a burning off process, in which parts are put into a large high-temperature oven with temperatures typically reaching an air temperature of 300–450 °C. The process takes about four hours and requires the parts to be cleaned completely and re-powder coated.
Powder coating is one common curing oven use. Drying ovens – Designed to remove moisture. Typical applications are pre-treating and painting. Such ovens are also sometimes known as kilns, though they do not reach the same high temperatures as are used in ceramic kilns. Baking ovens – Combines the function of curing and drying ovens.
At typical coating application temperatures, usually in the range of 180 to 250 °C (356 to 482 °F), the contents of the powder melt and transform to a liquid form. The liquid FBE film wets and flows onto the steel surface on which it is applied, and soon becomes a solid coating by chemical cross-linking, assisted by heat.
Powder coating on glass is used in industries such as cosmetics, fragrances, wine and spirits, where the contents inside of the glass containers require protection from ultraviolet (UV) rays, particularly UVA electromagnetic radiation, which is capable of penetrating glass [2]. When applied with a dual-coat method, powder coating techniques on ...
A gradient oven tester is a testing instrument which simulates the conditions of a production oven in the lab. It is used to test the baking and drying properties of liquid/powder coatings, resins, plastics, etc. and can determine how these materials will react when placed under extreme stress from heat, but more importantly can determine the temperature needed for drying as well as how long ...
