Electrical and Industrial Applications
Duralco Thermally Conductive adhesives 1
®
and potting compounds provide the heat
dissipation required for many high temperature
electronic and industrial applications. These 2
ultra temperature adhesives combine a unique
polymer system and specially thermally
conductive fillers to provide continuous service 3
up to 340ºC. They have excellent adhesion to
glass, ceramics, metals and plastics. Resistant
4
to most chemicals and solvents.
Duralco 128 - 260ºC Ceramic based 5
Is a highly thermally conductive, electrically
resistant adhesive potting compound. Just mix
the resin and hardener, apply and cure at room 6
temperature. Curing may be accelerated with
mild heat.
7
Duralco 132IP - 260ºC Aluminium based
An Aluminium metal filled epoxy that cures
at room temperature to form machinable, 8
thermally conductive bond lines, providing the
max. heat transfer available in a 260ºC epoxy
system. Can be supplied as a no-sag putty, 9
Duralco 132P, for heat tracing applications.
10
Duralco 133 - 315ºC Aluminium based
A two component, heat curing, Aluminium
filled, conductive epoxy. Cures with mild heat
11
to form thermally conductive bond lines and
heat transfer medium. It is readily machinable
and ideal for all kinds of repairs and as a 12
construction material.
