Dismantling Plastic Tailgates Incorporating INDAR Technology

SpecialChem / JEC Composites Magazine – Oct 10, 2012

Some 66 million adhesive-bonded windscreens are replaced worldwide every year. In Europe alone, nine million end-of-life vehicles generate more than two million metric tons of non-metal waste (glass, plastics and composites). The use of removable adhesives would help to considerably reduce the environmental impact of future vehicles, in compliance with ELV Directive 2000/53/EC. The INDAR dismantling technology (INDAR Inside®) involves formulating new adhesives and primers or reformulating commercial adhesives so that they can be easily removed at ambient temperature following heat activation. This results in clean and easily reusable surfaces following disassembly. This method comprises two main stages: 1) migration of the active components to the joint/substrate interface, and 2) splitting of the interface under the action of gases generated by the additive.
