摘要:
Continuous webs of self supporting adhesive sheet incorporating at least one layer of a polymeric composition such as polyvinyl butyral and comprising at least one area of a non-uniform thickness profile are provided. These webs are useful in the production of barrier windshields for heads-up display systems. The windshields may also optionally have acoustic barrier properties.
摘要:
A self-supporting adhesive web 10 having a uniform thickness profile across at least 20% of its width as shown by areas A and B and a wedge-shaped thickness profile in areas C and D. As shown in FIG. 2, a laminate comprises sheets of glass 12 and 14 having sandwiched therebetween adhesive interlayer 16. Interlayer 16 has a uniform thickness profile extending from edge 18 to point 20 and a wedge-shaped thickness profile from point 20 to edge 22.
