2、PEThe material defined by this specification is a two side pressuretransparent non-woven fiber tape, protected with release paper. Theadhesive is based on acrylate resins.2. APPLICATIONThe mat erial is generally used to bond PVC sheeting to clean and greasefree sur faces (e.g. door inner panel) and/

3、or for other applications asspecified on Engineering drawing.3. REQUIREMENTS3.1 COLOR Colorless-transparent3.2 THICKNESS 0.065 - 0.120 mm(ASTM D 1000)Without release paper.3.3 WIDTH As specified on Engineeringdrawing (see 5.2.)3.4 LINER REMOVAL, max 0.95 N/25 mmTest Method: Apply the unlined side of

4、 the tape to a clean metalpan el and measure the force required to peel the liner from theadhesive using the test procedure outlined in ASTM D 1000, Method A.3.5 BRAKING STRENGTH, min 12 N/25 mm(ASTM D 1000)3.5.1 Elongation, max 3 %ENGINEERING MATERIAL SPECIFICATIONSK-M3G9503-AWP 3948-b Page 2 of 53

8、 SK-M2F9504-A) and bond undermaximum finger pressure.4) After 2 hours at room temperature fill the assembly with dewaxingco mpound and suspend in vertical position for 24 hours at roomtemperature.3.9 COLD ADHESION No chippingTest Method:1) Apply a 20 x 19 mm piece of tape to a degreased aluminum foi

9、l(150 x 60 x 0.2 mm) under maximum finger pressure.2) After 2 hours at room temperature expose assembly and a 10 mmdiameter mandrel at - 30 +/- 1 C for 2 hours in a cold box.ENGINEERING MATERIAL SPECIFICATIONSK-M3G9503-AWP 3948-b Page 3 of 53) While still in the cold box, bend the specimen through a

10、n angleof 180 deg in 5 s econds around the mandrel with tape facing awayfrom the mandrel.3.10 QUALITYThe material shall be a smooth, homogeneous mixt ure free from foreignmaterials and properties detrimental to normal production use.3.11 TOXICITYThe material shall be non-toxic and shall not cause sk

11、in rash orirritation to exposed handlers in normal production operations.3.12 SUPPLIERS RESPONSIBILITYAll materials supplied to this specification must be equivalent inal l characteristics to the material upon which approval wasoriginally granted.Pri or to making any change in the properties, compos

12、ition,constr uction, color, processing or labeling of the materialorig inally approved under this specification, whether or not suchchange s affect the materials ability to meet the specificationrequir ements, the Supplier shall notify Purchasing, Toxicology andthe affected Materials Engineering act

13、ivity of the proposed changesand obtain the written approval of the Materials Engineeringactivity. Test data, t est samples and a new code identification areto be submitted with the request.Substance restrictions imposed by law, regulations or Ford, apply tothe materials addressed by this document.

14、The restrictions aredefined in Engineering Materials Specification WSS-M99P9999-A1.4. APPROVAL OF MATERIALSMat erials defined by this specification must have prior approval by theresp onsible Materials Engineering activity. Suppliers desiring approvalof thei r materials shall first obtain an express

15、ion of interest from theaffec ted Purchasing, Design and Materials Engineering activity. Uponrequest, the Supplier shall submit to the affected Materials Engineeringactivity a completed copy of their laboratory test reports, signed by aqualified and authorized representative of the test faci lity, d
