SCOPE The material defines performance requirements of adhesive foam tapes used for interior/exterior automotive application. The tapes are coated on both sides with a pressure sensitive adhesive and protected wi
3、th a release liner. 2. APPLICATION This specification was released originally to define adhesion performance requirements to retain interior and exterior trim parts including script ornaments, emblems, and badges. Applications require alcohol wipe or lint free dry wipe prior to attaching any parts.
4、The bonding surface shall be free from contaminates prior to attaching any parts. 2.1 LIMITATIONS This tape is not recommended to be used for body side moldings, claddings, wheel flares, rocker moldings, and spoilers applications; except where mechanical attachments are used in conjunction with the
5、tape. The tape alone is not recommended to retain these parts to the vehicle. Assembling these parts below 16 C is not recommended. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for Producti
6、on Materials (WSS-M99P1111-A). 3.2 TAPE PERFORMANCE MANAGEMENT All tapes evaluated to this specification must have Supplement A completed filled out and signed by Ford Materials Engineering, the tape supplier, and the tier one supplier. Compatibility of the tape with base material is the responsibil
7、ity of the tier one supplier. Any change will require a resubmission of supplement A. Tape approved to this specification must be tested to all current production paint systems and any newly developed paint systems as stipulated in VOP PTG-205. In addition to the requirements listed in this specific
8、ation, requirements listed in the appropriate SDS for the application must be met, unless otherwise agreed to by Ford engineering.

37、.3.1 Application Temperature, min 16 C Mating surfaces should be matched (contoured or parallel) to insure 100% contact of the bond area. For maximum adhesion, tape should be applied to freshly painted surfaces. When tape is applied to part prior to assembly, the part shall not be subjected to a pai
