THERMAL CONDUCTIVE ADHESIVE
DESCRIPTION
HERNON 746 is an excellent thermally con-
ductive two-component adhesive with ex-
tremely fast curing. It offers effective thermal
bonding of electronic components to heat
sinks. The material has an outstanding bond-
ing property so that mechanical devices are
no longer required.
The adhesive comprises a paste-like adhe-
sive and a fluid activator. The components
are not mixed. Apply a small amount of the
adhesive to the surface to be bonded and the
activator to the other bonding surface. Press
together to bond. Necessary corrections can
be made within 15-30 seconds. The bond is
secure after 5 minutes at room temperature
and is fully cured within 24 hours.
Extensive tests are evidence of the excellent
thermal and mechanical properties of
HERNON 746.
HERNON 746 fulfils the extremely strict re-
quirements with regard to thermal, mechani-
cal, chemical and environmental pollution.
Vibration tests of 10g show no negative ef-
fects. After performing extensive tempera-
ture, humidity and ageing tests, HERNON
746 not only fulfils but actually exceeds by
far the basic properties with regard to tensile
strength and thermal conductivity.
APPLICATIONS
HERNON 746 bonds heat sinks to compo-
nents and parts. It also allows parts and
components to be bonded reliably not only to
vertical cooling surfaces but also to metallic
housing surfaces and side panels without
having to use clips, screws or other me-
chanical forms of fixture. Typical applications
include the bonding of transformers, transis-
tors, microprocessors and other heat-
generating components to PCBs or coolers.
HERNON 746 is particularly suitable for
bonding LED chips to heat sinks.
HERNON 746 has numerous advantages
compared to traditional adhesive bonds, e.g.
thermal hot melt adhesive or epoxy adhe-
sive. It ensures permanent use and reliably
complies with the thermal and technical
properties. The adhesive is easy to apply
and thus considerably reduces both produc-
tion costs and service repair times.
Surfaces to which HERNON 746 adhesive
and activator have been applied can be sub-
jected to virtually unlimited pause times with-
out the properties of the bonding surface de-
teriorating.
HERNON 746 offers substantial cost advan-
tages compared to mechanical fixtures or
liquid adhesives which frequently necessitate
extensive investments in the production pro-
cess and equipment.
