Abstract
Improvements in manufacturing processes of rigid and portable reflective surfaces essentially characterized in that they consist of depositing on a metal sheet of thickness less than one millimeter conventionally linked to a support sheet suitable for drawing, a layer of a white adhesive on which a metal sheet extends. Layer of a heat-polymerizable resin, such as polyvinyl chloride, neoprene or polyurethane with a viscosity of approximately 25,000 centipoise and a minimum thickness of ten microns, whose resin is white and receives a dosage of reflecting glass micro-spheres whose granulometry is of the order of fifteen to thirty microns, which are stuck in the resin up to fifty percent of its diameter, passing then by a drying operation at a temperature between 110 and 160ºC and a time of 6 to 15 minutes after which and once cooled, the microspheres receive a layer of transparent resin from vi scosity and nature similar to the white resin layer, finally passing a drying operation at a temperature comprised between 110 and 160ºC for a time of 6 to 15 minutes.
