Low viscosity methyl cyanoacrylate with superior bonding properties

Key Features

  • One component, non-mix system
  • Excellent adhesion, especially to metals
  • Fast setting with rapid fixture time
  • Industrial grade

Product Description

Master Bond MB306 is a single component methyl cyanoacrylate adhesive. MB306 is a low viscosity, rapid setting cyanoacrylate system. 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. (See chemical resistance table.) The service temperature range for this system is -60°F to +200°F. MB306 is a versatile, high performance, industrial grade methyl cyanoacrylate that can be used in many different applications in the aerospace, electronic, OEM, electrical, optical and R&D industries.
