SCOPE The material defines performance requirements of adhesive tapes used for exterior automotive applications. The tapes are coated on both sides with a pressure sensitive adhes
3、ive and protected with a release liner. The tape carrier may be foam or non-foam type. 2. APPLICATION This specification was released originally to define adhesion performance requirements to retain exterior body side moldings. Several exterior trim components may be attached using these tapes, incl
4、uding but not limited to fascia/bumper inserts, claddings, wheel flares, appliqus, roof ditch moldings, step pads, rocker moldings, and spoilers. 2.1 LIMITATION Assembling these parts below 16 C is not recommended. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers
5、 and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.2 TAPE PERFORMANCE MANAGEMENT All tapes evaluated to this specification must have Supplement A completely filled out and signed by Ford Materials Engineering, the tape supplier, and th
6、e tier one supplier. Compatibility of the tape with base material is the responsibility 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 a
7、s stipulated in VOP PTG-205. In addition to the requirements listed in this specification, requirements listed in the appropriate SDS for the application must be met, unless otherwise agreed to by Ford engineering. 3.3 FINISHED PARTS Testing must be conducted at Design Verification (DV) and Process
8、Validation (PV) per Table 1Unless otherwise agreed to by Materials Engineering, and on actual production parts or a section of the part whenever possible. Where part dimensions limits test equipment access, representative test samples may be substituted. PV Testing must be conducted on actual produc
9、tion parts.

ENGINEERING MATERIAL SPECIFICATIONWSS-M11P65-A2 Printed copies are uncontrolled Copyright 2008, Ford Global Technologies, LLC Page 7 of 8 4.3 PRODUCTION APPLICATION METHODS 4.3.1 Application Temperature, min 16 C Mating surfaces should be matc
35、hed (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 paint and bake cycle. Once a pressure sensitive tape-backed ornament has
36、 been bonded, and for any reason removed (in-plant pull test), it shall not be reused. If the adhesive surface of the pressure sensitive tape becomes soiled, the pressure sensitive tape-backed ornament should not be used. The adhesive side of tape, shall not be touched or handled, once release paper
