Material Notes:
Features superior bonding properties. Master Bond MB306 is a single component, low viscosity, rapid setting, methyl cyanoacrylate adhesive. Similar to other types of “super glue”, MB306 cures very rapidly with the rate of cure dependent upon the humidity—the higher it is, the faster the cure. Because curing is normally fast, minimal contact pressure is usually sufficient for bonding. It must be emphasized that this high strength system requires no heating or mixing. It typically sets up within 10-30 seconds depending upon the humidity and the substrates. The bond strength is exceptionally high in the shear mode. MB306 bonds well to a variety of substrates, such as plastics and rubbers, but it is most useful for bonding metals. It has reasonably good chemical resistance, especially to cleaning agents.
