ET5428
Permabond ET5428 is a thixotropic two-part epoxy developed for composite bonding. It offers high shear and peel strength, rapid cure and resistance to impact, vibration and elevated temperatures. The controlled-flow formulation is easy to apply where gap filling is required, and its cream color is matched for FRP bonding.
ET5428 supports efficient assembly of UAV frames, airframe sections and other structures made from carbon fiber, GRP, FRP and compatible composite laminates. The rapid cure reduces handling time in production, and the toughened bond is ideal for structural components exposed to flight vibration and impact.
