Overview of Belzona 7311
Belzona 7311 is a fatigue resistant adhesive, optimized for structural bonding applications requiring high mechanical strength, cleavage and shear resistance. Belzona 7311 is ideally suited for bonding applications subjected to cyclic and repeated load. As a specially designed adhesive, it offers the perfect alternative to mechanical fastenings/fixings and can be a viable alternative to welding, eliminating any need for hot work, making it a safe yet high-performance solution. This easy to mix product requires no specialist tools or equipment for application and cure and is suitable for both dry and wet service up to 60 °C (140 °F). With a high amount of performance data available from the development and testing of Belzona 7311, customers have the ability to perform finite element analysis (FEA) and model bonded assemblies. This allows a client to simulate the stresses the adhesive will experience in service to satisfy themselves that the Belzona 7311 solution is capable of performing against real-world forces it will be subjected to in use.

Frequently Asked Questions
What makes Belzona 7311 a fatigue-resistant adhesive?
Belzona 7311 is engineered for structural bonding applications subjected to cyclic and repeated load. Its formulation is optimized to resist peel and cleavage forces, making it suitable for bonded assemblies that experience repeated loading without progressive cracking or debonding.
Can Belzona 7311 replace welding?
Belzona 7311 can be a viable alternative to welding for many bonding applications such as equipment supports, brackets and handrails on steel substrates, staircases, ladders, and plate bonding. Because it does not require hot work, it is a safe option for facilities where welding is restricted or where heat-affected zones must be avoided.
What is the service temperature range of Belzona 7311?
Belzona 7311 is suitable for service between -30 °C and 60 °C (-22 °F to 140 °F) in both dry and wet conditions, making it suitable for a wide range of indoor and outdoor environments including immersion service.
