PERMABOND® ET5393 is a 1:1 mixable epoxy adhesive. It is fully toughened and ideal for structural applications exposed impact and vibration stresses. It is ideal for bonding different materials where differential thermal expansion is anticipated. ET5393 can be used to bond a wide variety of materials including plastics, composites and metals – in particular, stainless steel.
Unlike many other epoxies, ET5393 is less affected by low temperatures during cure and exhibits a reliable cure in colder conditions.
