The curing time stated in the technical data was determined in the laboratory. It can vary depending on the
adhesive quantity and component geometry and is therefore a reference value.
The heating time of the components must be added to the actual curing time. It depends on component size
and oven type. The specified curing temperature must be reached directly at the adhesive.
Increasing or decreasing the curing temperature and / or irradiation intensity shortens or prolongs the curing
time and can lead to changed physical properties.
Only a small part of the bonding should be light-fixed as the maximum build-up of adhesion is achieved by
pure heat curing.
The period of time between prefixation and heat curing should not exceed 1 h at room temperature (approx. +23 °C / 50 % r.h.).
The adhesive shows postcuring behavior. After heat curing at low temperatures and a short curing time, a
certain level of strength is already achieved. The adhesive postcures at room temperature and achieves a level
of strength corresponding to the curing temperature after approx. 24 hours.
Depending on the adhesive quantity used, exothermic reaction heat is generated which can lead to
overheating. In this case, a lower curing temperature is to be selected.
All curing or light fixation parameters depend on material thickness and absorption, adhesive layer thickness,
lamp type and distance between lamp and adhesive layer.
Prefixation is performed with light. Heat curing is mandatory.
Values measured after 24 h at approx. 23 °C / 50 % r.h., unless otherwise specified.
