Epoxy functionality
WebThe term epoxy specifically refers to the chemical functionality provided by the chemical elements C2H4O bonded into a cycle ether arrangement. More generally, epoxy refers to the reaction products of molecules containing multiple epoxy functionality with various chemical hardeners to from solid thermoset materials. Back to Glossary. WebThese epoxy resins are in the molecular weight range most suitable for use in epoxy solutions, powder coating and electronic applications. These products have a good balance of properties, including appropriate epoxy functionality for proper curing, good physical stability (sintering resistance), and good melt flow (low melt viscosity).
