SCOPE The material defined by this specification is a clear, paper backed, abrasion resista
3、nt urethane film with a water clear pressure sensitive adhesive. A clearcoat is applied over the urethane film to prevent film yellowing. 2. APPLICATION This specification was released originally for material used to provide localized stone chip protection on painted lower bodyside areas. This tape
4、is suitable for application to visible exterior areas over painted surfaces with or without PVC type stoneguard coatings. It has a high tack, 0.13 mm thickness adhesive. A dry surface is recommended for tape application. Tape dimensions and premask (with or without) are specified on the engineering
