Abstract: A technique for minimising “blooming” or “frosting” that may occur when bonding sub-components of an article together to form a composite component with an adhesive such as cyanoacrylate. Opposed bonding regions on surfaces of first and second sub-components are bonded by the adhesive and at least one of the opposed bonding regions is provided with a depression in its surface which is capable of receiving and containing an amount of uncured/curing adhesive. The depression is preferably shaped and dimensioned so as to contain the uncured adhesive while minimising the adhesive's surface area exposed to the atmosphere. The depression may be shaped as an elongate groove along at least a part of a bonding region, such as along at least a part of the periphery of a bonding region.
