PERMABOND® ET5392 is a 1:1 mixable epoxy adhesive. It is semi-toughened and ideal for structural applications exposed impact and vibration stresses. It is ideal for bonding different materials where differential thermal expansion is anticipated. ET5392 can be used to bond a wide variety of materials including plastics, composites and metals – in particular, stainless steel.
FEATURES AND BENEFITS
- Adhesion to a wide variety of substrates
- Full cure at room temperature
- Easy to apply
- Semi-toughened
- Good impact strength
