摘要:
An electrically heated laminated aircraft glazing including at least two sheets of glass and an interposed non-brittle thermoplastic interlayer. A bus bar and an electrically conducting film are located on the inwardly disposed surface of one of the sheets and the bus bar covered with a thin layer of polyisobutylene resin. Additional layers of polyisobutylene resin are provided between the interlayer material and selected glass areas to prevent delamination and cold chipping of the glazing with subsequent moisture ingress and bus bar failure.
