Coil Bonding

DELO KATIOBOND Key Features

Light-activated versions can be used in opaque applicationsVery fast curing to minimise process costsEpoxy base ensures dry surface after cureExcellent chemical resistanceOne-part, ideal for manual or automated processing

One of the component parts of automotive temperature control systems consists of a lacquered copper coil bonded to a PCB. Because the lacquer is temperature sensitive, heat cannot be used in the curing process. Also, as the coil creates a shadow zone, UV light cannot be used in order to avoid uncured adhesive.

Pre-activating an adhesive with light before joining the components is the ideal solution. The adhesive receives enough energy in the 5-second pre-activation process to fully cure in time, and there is enough adhesive visible after the joining process to illuminate for a further 10 seconds and therefore achieve high initial handling strength.

The final assembled parts are then tested to exacting automotive requirements: 1,000 hours storage at +125°C; 100 temperature cycles between -65°C / 20 minutes and +150°C / 20 minutes; 100 thermal shock cycles between -65°C / 5 minutes and +150°C / 5 minutes; & humidity testing for 1,000 hours at +85°C / 85% RH.
