Patent number: 5989638Abstract: The invention is directed to a method and apparatus for coating substrates by a liquid spray so as to avoid entrapment of gaseous bubbles, particularly air bubbles, in the coating and desirably to thereby obtain bubble-free coatings. More particularly, the invention involves spray applying the coating to a substrate in an atmosphere consisting of gases having appreciable solubility in the applied coating, such as carbon dioxide, such that gas bubbles that may become entrapped in the coating are removed after application by the gases dissolving into the coating and diffusing to the surface.Type: GrantFiled: May 13, 1993Date of Patent: November 23, 1999Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventor: Kenneth Andrew Nielsen
