PERMABOND® ET5422 is a thixotropic two-part adhesive with excellent resistance to impact and vibration. The controlled flow properties as well as its ease of mixing and application, enables the adhesive to be used where gap filling is required. Permabond® ET5422 has been found to provide exceptional performance even at elevated temperatures. Permabond® ET5422 has been specifically formulated for use in applications requiring toughness and high strength.
FEATURES AND BENEFITS
- Easy to apply
- High shear and peel strength
- Long open time
- High temperature resistance
