SCOPE These sp
3、ecifications define the performance requirements for an adhesive or adhesive system suitable for bonding headlamps, rear lamps, or other lamps of varying substrates. 2. APPLICATION WSB-M11P28-B: This specification was released originally for an adhesive or an adhesive system used to bond lenses to b
4、odies in construction of vented and non-vented lamp assemblies. WSS-M11P28-B2: This specification was released originally for an adhesive or an adhesive system used to bond lenses to bodies in the construction of vented lamp assemblies only. Use of this specification in non-vented headlamp assembly
5、applications is not recommended. Mechanical attachments may be required depending on the lamp design. If mechanical attachments are required, it shall be noted on the assembly drawing. Materials meeting these performance specifications are identified on the Corporate Approved Source List along with
6、specific substrates for each lamp design. Compliance with these performance specifications does not guarantee the adhesive or adhesive system will function for all potential applications on a vehicle. The specific design condition must be evaluated prior to release of these materials. 3. REQUIREMENT

12、oove plaques shall consist of materials molded by an approved source as recommended by Body Engineering. . Clean the surfaces to be bonded with a hot, soapy water solution. The soap shall be free-rinsing, similar to that used for glassware. After cleaning, the plaques are blown dry and aged at 23 +/
13、- 2 C for 24 h to insure dryness. . Dispense an adequate amount of adhesive into the groove plaque. After the appropriate open time for the adhesive being tested, the tongue is inserted into the adhesive filled groove. Remove any excess adhesive. Maintain proper alignment of the assemblies during cu
14、re. Cure the assemblies as indicated by the adhesive manufacturer. . Test the assemblies at a crosshead speed of 12.7 mm/minute. Note: Proper alignment of the test assembly is critical. Every effort should be made to maintain uniform tension across the bond area. Cleavage and/or peel of the bond are
15、a could yield inaccurate results. . Evaluate a minimum of three assemblies per condition. Report failure mode and peak load in newtons. 3.3 CREEP RESISTANCE (WSB-M11P28-B only) No slippage (ASTM D 1780, prepare test samples per para 3.2, apply a 4.5 kg dead weight load to test samples and expose to
