Single-Part Epoxies
Permabond single-part epoxy adhesives are suitable for bonding a wide variety of materials. They are available with a range of different
viscosities and with and without metal filler. Permabond epoxies have been developed to offer a high standard of performance for
demanding applications.
Substrates
Permabond single-part epoxy adhesives will bond most engineering materials. They
form excellent structural bonds to a wide variety of materials including metals,
composites, wood and even some plastics.
Material selection
By replacing welding or brazing, the designer can have greater freedom of choice of
manufacturing materials and can bond dissimilar substrates together. This can help
reduce component cost and weight and improve performance.
Durability
These adhesives offer excellent performance at high temperatures and harsh
environmental conditions, having superb resistance to strong chemicals.
Process
Adhesive is available in cartridge form or in bulk to dispense via automated dispensing
equipment. The adhesives cure rapidly when heated so it is necessary to use an oven to
cure the adhesive (or other method such as an induction coil, infra-red or a hot air gun).
Applications
Single-part epoxies are ideal for use in heavy wear-and-tear applications such as
bonding tungsten carbide tools & machinery. They are ideal for replacing welding and
brazing and can significantly reduce assembly production costs. For this reason their use
is widespread in the heat exchanger market for sealing heat exchanger tubes and endplates.
Joint Design
Joint design possibilities are greatly improved by the high shear and peel strength of
joints bonded with these adhesives because of the increased stress distribution that
they offer.
