Permabond ET5428 Two-Component Epoxy Adhesive, High Strength, 30-45 Min Cure Time, Gap Fill 5mm

Permabond ET5428 is a versatile two-part epoxy adhesive engineered for demanding bonding applications, especially with composite materials. This thixotropic adhesive delivers outstanding shear and peel strength while offering superior resistance to impact and vibration. With a rapid cure time of 30-45 minutes at room temperature, it achieves handling strength quickly and can be heat-accelerated for faster production. The adhesive maintains its exceptional performance across a wide temperature range, from -40°F to elevated temperatures common in paint baking processes. Its controlled flow properties and dual cartridge system enable easy application, with the ability to fill gaps up to 0.2 inches. Particularly effective for composite assemblies, this tough and durable formulation features color-matching for FRP bonding. The cured adhesive demonstrates a Shore D hardness of 65-75, making it ideal for structural bonding applications. For optimal results, surfaces should be clean, dry, and free from grease, with light abrasion potentially beneficial for certain metals.
