Aging Assisted Failure of SV-40 Epoxy

Abstract:

Perpex circular piece along with SV-40 epoxy was served as a viewing window of a glove-box over the period of 4 years. While in periodic pressurized operation, leakage occurred at 2 bar. For investigation, a fresh piece of the same Perpex glass and epoxy were used as reference. Visual observation, optical microscopy, hardness testing and Fourier transform infrared spectroscopy (FTIR) were utilized as characterization techniques. The FTIR spectrum revealed variation in transmission peaks in old epoxy as compared to new epoxy, which was due to secession and crosslinking within old epoxy over the lifespan. It could be inferred that the shrinkage of the epoxy effected interfacial bonding of Perpex and epoxy, therefore the assembly failed during pressured condition of the glove box.
