2、 Ford Global Technologies, LLC Page 1 of 7 PERFORMANCE SPRAYABLE COATING, ACOUSTIC, WSS-M99P30-A INTERIOR AND EXTERIOR, BODY PANELS 1. SCOPE This specification defines the performance requirements for solvent free material with good acoustical efficiency, which is applied to body panels either in bo
3、dy-in-white or in 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
4、and/or panel stiffening 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 bak
5、e process. Type 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
6、color coat. The material will cure through the primer surfacer and/or color coat bake process. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). Part p
7、roducers using this material in their products, must use Ford approved materials and must conform to a process control plan which has been approved by STA and/or the relevant Materials Activity. 3.2 FILM THICKNESS, Dry As specified on Engineering Drawing 3.3 ABRASION RESISTANCE (ASTM D 968, only app

Panels shall be cured for the min and max cycle times as stated in FLTM BV 150-05, Table 2 for paint shop applied materials or Table 1 for Body In White (BIW). 3.4.2 After conditioning for 24 h at 23 +/- 2 C, a) If material under test is applied onto iron or steel surfaces expose for 500
15、h to a salt spray fog according to ASTM B 117, or b) if material under test is applied onto zinc or zinc alloy coated steel test according to FLTM BI 123-01 alternatively 50 Cycles according to SAE J2334. 3.4.3 Examine for corrosion resistance. Disregard the area 10 mm from the edges of test panel.
