- Water filtration and separation are requirements in many industries for numerous applications. These include food and beverage, wastewater treatment and desalination, among others. The importance of water purification will only escalate as water scarcity becomes increasingly problematic in several regions, making resource maximisation essential.
- One of the most prevalent filters for liquid filtration is the hollow fibre filter, where thousands of hollow fibres separate water into two flow streams. Adhesive materials are a critical component of the filter assembly.
- Potting adhesives secure the fibre membranes into the housing, allowing for proper filter function, reliability, durability and longevity. However, the application process can be time-consuming, and current adhesives can’t bridge the gap between health and safety, manufacturing speed and robust assembly.
- Traditional manufacturing methods generally employ polyurethane- or epoxy-based adhesives for hollow fibre potting. Each chemistry platform—while functionally sound once cured—has challenges.
- Two-part polyurethane materials incorporate an isocyanate hardener component, which requires specialised handling procedures and introduces safety risks. Furthermore, polyurethanes are incompatible with wet fibres so, even though adhesive cure is fast, lengthy fibre drying time limits assembly rates. Epoxy-based adhesives, which are compatible with wet fibres, typically have slow cure rates and high exotherm, dramatically restricting production speed and output.
- To effectively balance safety, processing and application robustness, a material solution that can harmonise production throughput, membrane compatibility, static or centrifugal processes, and filter performance is required. Manufacturing adaptability within a high-volume environment is essential to meet current and future water conservation and reuse demands.
