Epoxy Resins

Epoxies shows some differences from polyester resins in that they are cured by a ‘hardener’ rather than a catalyst. The hardener, often an amine, is applied to cure the epoxy by an ‘addition reaction’ where both materials take place in the chemical reaction. The chemistry of this reaction means that there are usually two epoxy sites binding to each amine site. This forms a complex three-dimensional molecular structure.

Due to the amine molecules ‘co-react’ with the epoxy molecules in a fixed ratio, it is important that the proper mix ratio is obtained between resin and hardener to ensure that a complete reaction takes place. If amine and epoxy are not mixed in the correct ratios, unreacted resin or hardener will remain within the matrix which will influence the final properties after cure. To assist with the accurate mixing of the resin and hardener, manufacturers usually formulate the components to give a simple mix ratio which is easily achieved by measuring out by weight or volume.


DescriptionVO-ER-1100is a medium –viscosity unmodified liquid epoxy resin based on Bisphenol -A wide variety of curing agents is able to cure liquid epoxy resins at ambient conditions. The most frequently used are aliphatic polyamines, polyamides, amidoamines, cycloaliphatic amines and modified

versions of these curing agents. Curing may also be done at an elevated temperature to improve selected properties such as chemical resistance and glass transition temperature. If anhydride or catalytic curing agents are employed, elevated temperature cures are necessary and long post –cures are required to develop full end properties
