Devcon® MA216 is a flexible, two component acrylic adhesive product designed with low halogen content for structural bonding. It is well suited for structural bonding application on various substrates, such as metal and plastics, where temperature shock, vibration resistance and mechanical impact resistance are required. The product has a work time of 3-4 min and cures rapidly to form tough, resilient bonds. Once mixed with static mixer, the two component acrylic cures at room temperature to an extent approximately 50% within 10 minutes and the cure time can be reduced with the aid of mild heat to the bonded assemblies. Typical applications include structural bonding of plastic and metal components that must withstand vibrations and impacts such as in portable electronic device and specialty vehicle markets.
