Adhesives for Heat Exchangers

Adhesives are a cost-effective solution for sealing heat exchanger tubes onto endplates and are popular alternatives to welding or brazing. The result is a superior leak-free assembly. Adhesives offer design engineers the opportunity to choose lightweight but durable non-metal substrates and to combine dissimilar materials without sacrificing performance requirements. Adhesives can also be used for bonding heat exchanger fins and rubber gaskets to flat plate heat exchangers.

Permabond adhesives offer excellent resistance to oil, water, coolants and other gases. This makes them suitable for assembly and repair of all sizes of heat exchangers in a variety of industries, such as automotive, HVAC and marine.
