Glazing direct bonding adhesives on the frame of vehicles needs to be easily released for replacement & now for ELV dismounting. Among the present cutting, heating, wiring knives, laser, ultrasonic technologies, no one seems really able to dismount in a short time at nearly zero lifting off load & leaving clean interfaces. After 5 years of R&D, patent & know development, the so called "debonding technology" seems to solve the problems by suitable thermally expanded microspheres: TEM, mainly embedding in a primer matrix interface between the ceramic screen printing & the adhesive bead. Experimental results achieved the release of the glazing, included the windscreen, by IR suitable heating lamp in around 3 minutes with only about 1g of special TEM per glazing. Fast time, no lifting load, clean surface is now conceived a technology for massive applications.
