What kind of material is Epoxy Resins?
Usually identifiable by their characteristic amber or brown coloring, epoxy resins have a number of useful properties. Both the liquid resin and the curing agents form low viscosity easily processed systems. Epoxy resins are easily and quickly cured at any temperature from 5°C to 150°C, depending on the choice of curing agent. One of the most positive properties of epoxies is their low shrinkage during cure which minimizes fabric ‘print-through’ and internal stresses. High adhesive power and high mechanical properties are also improved by high electrical insulation and good chemical resistance. Epoxies find usages as adhesives, caulking compounds, casting compounds, sealants, varnishes and paints, as well as laminating resins for a variety of industrial uses.
Epoxy resins are formed from a long chain molecular structure similar to vinylester with reactive sites at either end. In the epoxy resin, however, these reactive sites are shaped by epoxy groups instead of ester groups. The absence of ester groups means that the epoxy resin possesses particularly good water resistance. The epoxy molecule also contains two ring groups at its center which are capable to absorb both mechanical and thermal stresses better than linear groups and therefore give the epoxy resin very good stiffness, toughness and heat resistant properties.
The figure below shows the idealized chemical structure of a typical epoxy. Note the absence of the ester groups within the molecular chain.
