  • Electrochromic safety glazing
    Patent number: 6995891
    Abstract: An electrochromic device is achieved that exhibits the characteristics of impact-resistant safety glass by starting with a solid electrolyte sheet material and a peripheral sealant material sandwiched between substrates to heat and pressure such that the electrolyte bonds to the treated surfaces of the substrates with an adhesion of at least 1.8 kg/linear cm width causing the electrolyte to exhibit a tensile strength of at least 5 kg/cm2.
    Type: Grant
    Filed: July 18, 2003
    Date of Patent: February 7, 2006
    Assignees: Schott North America Inc., Magna Donnelly Corporation
