ABSTRACT:
The bonding of polymeric panels with thermosetting adhesive compositions may lead to an unsightly image of the adhesive bond line on an external surface of the joined articles. This bond-line read-out is reduced or eliminated using an adhesive material with filler particles characterized by nanometer size clay platelets when the content of the filler particles does not exceed about five percent by volume of the uncured adhesive. Selective placement of the adhesive extending to the edges of the bonding surfaces of the polymeric members also reduces bond-line read-out.
