Araldite 2033, a flame
retardant adhesive from
Huntsman Advanced
Materials, has been selected by a
global white goods manufacturer to
help optimise manufacturing and
deliver good mechanical properties to
electronic components on a washing
machine.

This two component structural
adhesive allows the coil and printed
circuit board (PCB) to be preassembled
in accordance with the
specifier’s preferred manufacturing
techniques, enabling economical
joining combined with high
temperature resistance and room
temperature curing.

Huntsman says that when lab tests
were undertaken to investigate the
possibility of using a neutral RTV
silicone to assemble the electronic
components, during the wave
soldering process silicone boiled at
elevated temperatures and was not able
to maintain the components’ bond.

For this application, the adhesive
has to combine high toughness with
vibration resistance and good
temperature resistance.
