Water Based Epoxy Resin Chemistry

There are many types of epoxy resins and the chemical structure of an epoxy resin often used in aerospace composite materials is shown in fig.

Water based epoxy resin chemistry.

Epoxy resin is used as the matrix phase in carbon fibre composites for aircraft structures and as an adhesive in aircraft structural joints and repairs. Epikure waterborne curing agents are most often used in combination with epi rez waterborne resins. A two component water based acrylic epoxy resin coating water based catalyzed epoxy is formulated for high performance use in industrial and commercial environments. The water absorption increases the diffusion coefficient of water within the polymer.

They are also compatible with a variety of wetting agents additives co solvents and coupling agents to achieve enhanced properties. Epi rez waterborne epoxy resins together with epikure curing agents enable a wide variety of low or no voc end products with performance levels previously unthinkable for waterborne epoxy systems at a cost that is increasingly competitive with solvent borne technology. Epoxy resin is a chemical compound containing two or more epoxide groups per monomer and this molecule contains a tight c o c ring structure. Water based wetting agents additives co solvents and coupling agents can be added easily to speed drying enhance corrosion resistance increase adhesion and extend pot life.

Epi rez epoxy resins are easily adjusted with water making these systems highly adaptable. Experimental studies of water absorption by epoxy resins are discussed. These resin curing agent systems can generally be diluted to the desired solids level by simply adding water.
