scope:

The material defined by these specifications is a clear, release liner backed, abrasion resistant urethane film with a water clear pressure sensitive adhesive. Films B1 - B4 include a clearcoat applied over the urethane film to prevent film staining, yellowing, and increases weathering performance. Films B5 and B6 are typically not clearcoated.

To differentiate between locations requiring chip resistant testing, a CAE model or equivalent will be used to determine chip performance based on vehicle design. Ford engineers will determine areas of high and low chip probability. High chip probability areas should be avoided at large body character lines (I.E. wrapping bodyside exterior into door jamb). 200 micron or greater urethane film thickness (not including adhesive thickness) is typical for flat surface designs. 200 micron or less urethane film thickness (not including adhesive thickness) is typical for designs traversing large character lines, compound surfaces, or bends.
