Water Based Epoxy Resin Chemistry

Epi rez waterborne epoxy resins when properly formulated perform at levels consistent with solvent borne technologies while reducing vocs which enhances worker safety.

Water based epoxy resin chemistry.

Waterborne epoxy resins and curing agents. A two component water based acrylic epoxy resin coating water based catalyzed epoxy is formulated for high performance use in industrial and commercial environments. 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. 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.

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. Epikure waterborne curing agents are most often used in combination with epi rez waterborne resins. These resin curing agent systems can generally be diluted to the desired solids level by simply adding water. These studies show that absorption can disrupt hydrogen bonds among segments of the polymers and cause swelling of the polymer.

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. Epi rez epoxy resins are easily adjusted with water making these systems highly adaptable. The water absorption increases the diffusion coefficient of water within the polymer.
