Patent number: 10942302Abstract: A solar reflective mirror includes a parting film between solar reflecting sublayers to improve optics and stability of the solar mirror. The coating stack of the solar reflector mirror is encapsulated to increase the useable life of the solar mirror, and to eliminate the need for a permanent protection overcoat. Omission of the PPO film which is electrically non-conductive makes the coating stack electrically conductive eliminating the need for a two layer encapsulant when the encapsulant is e-coated. Another feature of the invention is applying the base coat of the encapsulant over the marginal edges of the PPO film leaving a center section without coverage and adding the top coating of the encapsulant over the base coat and the uncoated area.Type: GrantFiled: July 13, 2016Date of Patent: March 9, 2021Assignee: Vitro Flat Glass LLCInventors: Paul A. Medwick, John D. Basil, Benjamin Kabagambe, James W. McCamy, Harry Buhay
