Abstract
A composite switchable pane array, having: a first pane; a second pane, and an intermediate layer arranged therebetween, wherein the intermediate layer has at least one first thermoplastic polymer film and one second thermoplastic polymer film, and an SPD film arranged therebetween; and an edge sealing arranged in the outer edge region of the intermediate layer, containing a polyimide (PI) and/or polyisobutylene (PIB).
Claims7
A switchable composite pane arrangement, comprising:
- a first pane;
- a second pane;
- an intermediate layer arranged therebetween, wherein the intermediate layer contains at least one first thermoplastic polymer film and one second thermoplastic polymer film as well as one suspended particle device (SPD) film arranged therebetween;
- and
- an edge sealing comprising an at least 1-mm-deep notch formed in a surface region of the intermediate layer away from the first pane and the second pane that is filled with polyisobutylene (PIB) and/or polyurethane (PU),
- wherein the notch reaches the SPD film and extends laterally to the outer edges of the first and the second thermoplastic polymer films, and
- wherein the notch is formed after laminating the first pane, the second pane, and the intermediate layer.

A method for producing a switchable composite pane arrangement, comprising:
- arranging a suspended particle device (SPD) film between a first thermoplastic polymer film and a second thermoplastic polymer film to form an intermediate layer,
- laminating the intermediate layer between a first pane and a second pane,
- after laminating the first pane, the second pane, and the intermediate layer, milling or scratching a notch at least 1 mm deep in a surface region of the intermediate layer away from the first pane and the second pane, wherein the notch reaches the SPD film and extends laterally to the outer edges of the first and the second thermoplastic polymer films, and
- filling the notch with polyisobutylene (PIB) and then polyurethane (PU) to provide an edge sealing arranged in the edge region of the intermediate layer.
