Abstract
A window assembly for a vehicle having an essentially chlorine-free modified polyolefin primer (24) disposed onto a transparent pane (12) and a two-shot encapsulant applied onto the primer is provided. The two-shot encapsulant includes a first encapsulation layer (22A) disposed on the primer (24) and a second encapsulation layer (22B) disposed on the first encapsulation layer (22A). The first encapsulation layer (22A) has a Shore D hardness of at least 39 and a Flexural modulus of at least 100 MPa, while the second encapsulation layer (22B) has a Shore A hardness of less than 90.
