SCOPE The materials defined by these specifications are the separate parts of a two

3、 pack, epoxy base, solvent-free and room temperature curing structural metal to metal adhesive. WSK-M2G400-A is a modified epoxy resin based on Bisphenol A. WSK-M2G400-B is a modified polyamine hardener. 2. APPLICATION These specifications were released originally for materials used for bonding roof

4、 to body side panel (cold rolled steel, sanded and wiped by cleaning solvent) only for repair. Mechanical structural adhesive properties are dependent on bondline thickness. In the uncured state, the adhesive can be welded. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material

After application follow up welding operations must be executed within two (2) hours. Within these two (2) h

10、ours the adhesive film shall have sufficient conductibility to have a spot weld applied to the metal beneath the film. The tests must be executed according to FLTM BV 109-01 with the following changes: - Application of material by gun or cartridge - 25 coupon assemblies per condition - Steel substra

11、tes only - Assembly aged at 23 +/- 2 C for 2 hours - The investigation (point 6 in FLTM BV 109-01) after 30 days is not required. 3.8 QUALITY The material shall be a smooth homogeneous mixture, free from foreign materials. It must be adaptable for application in accordance with the appropriate Ford
