SCOPE The materials defined by these specifications are a series of single component
4、, self-curing, anaerobic compounds which remain liquid as long as they are exposed to air and solidified by polymerization (not solvent evaporization) without significant shrinkage when confined between closely fitted metal parts in the absence of air. 2. APPLICATION These specifications were origin
5、ally released for applications requiring single component industrial quality adhesives formulated for assembling and adhering metals. Certain metals may accelerate the polymerization process. WSK-M2G348 - Gasketing A1 Flowable anaerobic material; slightly flexible when cured; 130 C continuous use te
6、mperature; best suited for rigid heavily bolted ferrous metal flanges 6 mm diameter; for gaps 0.25 mm. A10 A flowable thixotropic anaerobic adhesive; high strength when cured for permanent locking of studs or fasteners; lubricates fastener assembly; gaps 0.25 mm; 150 C continuous use temperature. 3.
