SCOPE This specification defines the performance requirements for solvent free material with good acoustical efficiency, which is applied to body panels either in body-in-white or i

3、n the paint shop. 2. APPLICATION This specification was originally released for materials to be sprayed on or applied with wide slit nozzle in visible or non-visible areas of roof, floor, side panel, rocker panel, doors, liftgate etc. where body panel damping, gravel noise reduction and/or panel sti

4、ffening is required. The material is applied onto oily surfaces or dry electrocoat. Type 1: The coating is applied to an oily metal surface prior to cleaning, phosphating and paint process. The material is hot applied and will set after cooling to room temperature without further bake process. Type

5、2: The coating is applied to an oily metal surface prior to cleaning, phosphating and application of electrocoat. The material will cure during the electrocoat bake process. Type 3: The coating is applied to an electrocoated metal panel prior to application of primer surfacer and/or color coat. The

6、material will cure through the primer surfacer and/or color coat bake process. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing
