Evaluation of Epoxy Quality by Determination of Volatile Organic Compounds (VOCs)

Introduction

Epoxy resins are important CASE (coatings, adhesives, sealants, elastomers) materials for industrial and consumer applications due to their versatility. Epoxy resins can be designed as adhesives or for coatings, they can be formulated to withstand high temperatures, are moisture and chemical resistant, have a high degree of flexibility, and strong adhesive strength properties for binding materials. For these reasons, epoxy resins are widely used in the production of lightweight automotive and aerospace components, thus it is important to analyze and understand the properties of epoxy resins.

This application brief demonstrates that common epoxies can be effectively analyzed by GC/MS-HS (gas chromatography mass spectrometry with headspace injection) as well as the identification and quantitation of the off-gasing that occurs. In this instance the amount of off-gasing that was measured correlated to the quality of the epoxy. Download the application brief to learn how utilizing GC/MS-HS is an effective analytical solution which utilizes direct injection.
