When faced with joining two materials, a designer has numerous choices. With the intensive research into adhesion and the resulting new adhesive technologies currently available, adhesive bonding is a popular option. When one starts looking for a structural adhesive the choices beging to narrow. Some of the leading candidates for structural applications are epoxy, urethane and methacrylate chemistries. To decide on the best adhesive one must evaluate the substrates to be bonded, the mechanical property requirements, and the ability of the adhesive to meet the physical requirements. This paper will be an in depth discussion of methacrylate adhesives, their properties, and the wide range of substrates they are able to bond.
