Quality Control of Epoxy Resins

Epoxy Resins

Epoxy resins find applications in a wide variety of industries, and are used for the production of coatings, adhesives, laminates, casting materials, etc. Traditionally, simple analytical characteristics (e.g. content of epoxy groups, chlorine, α-glycol groups, viscosity or softening point) are used to identify epoxy resins. But these quantities are often unable to distinguish among particular samples and to find relations between the epoxy structure and its properties. Now with a DAWN® or miniDAWN® coupled with size exclusion chromatography (SEC), epoxy resins can be fully characterized.
