Structural bonding is replacing mechanical fastening-bolt, screw, clip or weld-throughout the assembly process. Structural adhesives cover the entire bond area, often creating a stronger bond than traditional, intermittently spaced fasteners.
Structural adhesives are designed to bond metal to metal or to plastic, fiberglass or other substrates. Typical adhesives include two-component epoxies or modified acrylics. In many cases, these high-viscosity adhesives have various mix-ratios, a rapid cure time, and require special handling for optimum performance.
