Description
Belzona 7311 emerges as a robust adhesive engineered for structural bonding tasks that demand exceptional mechanical strength, as well as resistance to cleavage and shear forces. It is the perfect match for applications that undergo cyclic and dynamic loads.
This adhesive is crafted as a superior substitute for traditional mechanical fasteners and welding, offering a no-heat-required, high-performance bonding solution. It is adept at handling both dry and wet conditions, maintaining its efficacy up to 60°C (140°F).
Belzona 7311 is backed by extensive performance data, enabling customers to conduct finite element analysis (FEA) and create models of bonded structures. This empowers users to predict and verify the adhesive’s performance under actual service stresses, ensuring it meets the demands of real-world applications.
Frequently Asked Questions
What is the recommended surface preparation for Belzona 7311?
The recommended surface preparation for Belzona 7311 is abrasive blasting to the cleanliness requirements of SSPC SP 10 or ISO 8501-1 Sa 21/2 achieving a minimum average surface profile of 75 microns (3 mil).
Could vapor blasting surface preparation be used prior to application of Belzona 7311?
Yes, vapor blasting can be used for both internal and external applications.
How will the level of surface preparation affect the mechanical properties of the product?
Surface preparation is key to success for all Belzona applications. Carrying out the best surface preparation will assist in ensuring the most effective bond possible, which is crucial in providing the high mechanical strength, cleavage and shear resistance associated with Belzona 7311.
What is the recommended application thickness of Belzona 7311?
For adhesives, a thin, uniform bond line is preferred to avoid introducing voids and stresses within the joint. Therefore, when applying Belzona 7311, we would recommend a bond line thickness of no greater than 2mm.
Is it possible to force cure Belzona 7311 for a faster return to service?
Yes, the material can be force-cured in accordance with section 5 of Belzona 7311’s Instructions for Use.
Is Belzona 7311 suitable for immersed environments?
Belzona 7311 has been subjected to long-term water immersion testing and has shown had no detrimental effect to the mechanical properties of the product. However, it’s always best practice to overcoat with a suitable Belzona coating for further protection against chemicals, erosion and abrasion.
