ABSTRACT:
A thin transparent glass sheet is bonded to the substantially flat planar front face of a cube-corner-type retrodirective reflector formed of a light-transmitting synthetic organic resin for covering at least the reflex reflective area thereof. A liquid urethane resin radiation curable to a transparent solid state is applied to the front face of the reflector and one side of the glass sheet is coated with a silane solution which is allowed to dry, and which side is then placed against the urethane resin on the reflector front face and pressed thereagainst until all air bubbles have been forced from the urethane resin and it has spread to a layer of predetermined thickness. The resulting laminate is preheated to a temperature approximating the maximum temperature expected to be experienced in use and then, while at the elevated temperature, the urethane resin layer is radiation cured, for bonding the glass sheet and the reflector together, curing at this temperature causing the adhesive to set so that the glass will be under compression when the laminate is exposed to the working temperature range, and the laminate is then maintained at about 150.degree. for 30 to 60 minutes to enhance the chemical bonding of the silane to the glass and the adhesive.
