SCOPE The material defined by these speci

3、fications is an epoxy base, polyester modified (not for A3), mineral filled, pumpable, solvent-free and heat curing structural metal to metal adhesive. The structural adhesive physical properties are valid for an adhesive thickness from 0.3 to 7.0 mm (for A3 0.1 to 1.0 mm). Mechanical structural adh

4、esive properties are dependent upon bondline thickness. 2. APPLICATION These specifications were released originally for material used for bonding the roof to the body side panel. Assembling of parts to be bonded has to be possible immediately after adhesive application as well as after cooling of a

5、dhesive to 23 +/- 2 C. The materials are applicable on oiled surfaces with acceptable oil film weights (European applications limit the oil/pre-lubricant film weight to max 3 g/m, see Performance Specification WSK-M11P47 paragraph 3.6). Note: Care must be taken to ensure that the local oil film weig

6、ht in the area of the adhesive/sealer application does not exceed the critical limit. Monitoring of the film thickness, adequate storage of the part and/or cleaning of the surface prior to sealer/adhesive application is necessary to avoid critical film thickness values, which would then cause malfun

7、ction of the sealer/adhesive. 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). 3.2 COMPOSITION Modified Epoxy, based on Bisphenol A and Bisphenol F.
