Abstract
This application note demonstrates Evolved Gas Analysis (EGA) and Multi-step Pyrolysis (MSP) with GC-MS on cyanoacrylate glues.
Introduction
Cyanoacrylate adhesives, first patented in 1949(1) and marketed under the trade names Super Glue and Krazy Glue, bond nearly instantly to surfaces. The cyanoacrylate monomer polymerizes quickly in the presence of water, forming strong chains. While standard cyanaoacrylate glues can be nearly 100% cyanoacrylate, custom formulations also exist.
As a powerful analytical tool in failure, competitor, and even forensic analyses, Evolved Gas Analysis together with Multi-step Pyrolysis is supportive of discovering chemical components in finished materials. In this application note, two formulations of cyanoacrylate glues were explored.
