Permabond’s line of adhesives and sealants offers the performance characteristics needed to bond all the different substrates used in manufacturing various filters. Filter adhesives for bonding and potting, as well as crimp sealing are available.
Our adhesives find uses in a variety of filter applications. Let’s take the rolled seam on a filter base plate, for example. Rolled seams in oil filters, fuel filters, and air filters are formed by cold rolling the edges of two metal flanges like the lid of a tin can. These seams need to be sealed, and anaerobic sealants and rubber-based solvent sealants are very effective at doing this. On one hand, rubber-based solvents tend to be cheaper than anaerobic sealants. Anaerobics are, however, far less toxic and risky in comparison, are non-flammable and better suited towards automation.
Another example is sealing disc-shaped filters. Process industry filters made of a metal housing and metal mesh media can either be welded or sealed. Many professionals choose either an anaerobic or an epoxy adhesive here, depending on end use requirements. Disc-shaped filters in plastic housings likewise have similar considerations, with UV curing adhesives often a good choice for these. For more information on these applications, read our more in-depth post here.
