Abstract
A window assembly for a vehicle having an essentially chlorine-free modified polyolefin primer disposed onto a transparent pane and a two-shot encapsulant applied onto the primer is provided. The two-shot encapsulant includes a first encapsulation layer disposed on the primer and a second encapsulation layer disposed on the first encapsulation layer. The first encapsulation layer has a Shore D hardness of at least 39 and a Flexural modulus of at least 100 MPa, while the second encapsulation layer has a Shore A hardness of less than 90.
