VK series Magnetron Sputtering Solar Control Window Film
Magnetron sputtering solar control window film is a type of window film that uses a special coating process to block heat and ultraviolet (UV) rays from the sun. This type of film is made by sputtering a thin layer of metal atoms onto a polyester film base. The sputtering process is done in a vacuum chamber, where a magnetron gun is used to create a plasma of metal ions. These ions are then accelerated towards the polyester film base, where they bond to the surface.
