The adhesive must be fully cured for an effective and durable joint to be formed. Most engineering adhesives will display an odour when in the uncured state and, once cured, the adhesive is essentially a thermoset or thermoplastic and so inert and usually without odour. One key inspection technique therefore when trying to establish the reason for the failure of an adhesively bonded joint is simply to check for any odour in the bond line and compare this to a bottle of the original adhesive. Any sign of odour usually suggests that the adhesive has not fully cured.
