4、NS FOR HIGH IMPACT AREAS TAPE, NON-TOPCOATED, URETHANE, PRESSURE SENSITIVE, CHIP WSS-M99J291-B6 RESISTANCE, NON- VISIBLE APPLICATIONS FOR MODERATE IMPACT AREAS 1. SCOPE The material defined by these specifications is a clear, release liner backed, abrasion resistant urethane film with a water clear

5、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

6、equivalent will be used to determine chip performance based on vehicle design. Ford engineers will determine areas of high and low chip probability. 2. APPLICATION These specifications were released to provide localized stone chip protection on painted body surfaces. A clean surface is recommended f

7、or tape application. A wetting solution (25% isopropyl alcohol/75% deionized water or S-802 Decal Lube or equivalent) may be recommended by the supplier to aid in application. Tape dimensions and premask (with or without) are specified on the engineering drawings. 3. REQUIREMENTS All testing to be d

8、one on finished production parts (i.e., film to be used to design intent and application on production substrate/paint).
