Why use water based epoxy resins and hardeners?
Since the discovery of the ambient curing epoxides and amines and the commercialisation of bisphenol-A based epoxy resins, two component epoxy amine systems have conquered a large part of the coatings, composites and adhesives market. This success is largely attributable to the excellent intrinsic properties of these systems, which are:
Low volume shrinkage upon cure
Thirty years after these discoveries allnex, noticed the potential of these systems in waterborne applications. Already in the early 1960’s the foundation of our waterbased epoxy and amine adducts portfolio was built. The advantage of using water based 2K epoxy systems, is the fact that these are much lower in VOC at lower viscosity, while most of the intrinsic properties remain intact. This enables lower film build, easier application and faster dry. Our portfolio covers a wide variety of applications such as:
In many segments such as Agricultural – Construction - Earthmoving equipment (ACE), Rail, Industrial metal and Civil engineering, allnex has been the frontrunner in creating a more sustainable environment. Recently, when the Chinese shipping-container market made a step-change with moving entirely to waterborne systems, allnex has been instrumental in this journey with localized supply. Today we keep innovating to lower the VOC and environmental impact of our products, also making them benzyl-alcohol-free, BTX-free or HAPS-free or reducing the amount of free-amines.
We focus on market needs and regulations but also provide tailor made solutions. If you are wondering how to formulate 2K waterbased epoxy systems, please have a look at our epoxy webinars or reach out to our technical experts. To make specific product selections please use our product selector found below where you’ll find a variety of epoxy resin dispersions and hardeners of varying molecular weight and equivalent weight.

Tips and Tricks
Additives for your water based epoxy formulations
With the increasing demand of water based industrial coating systems, additive producers are challenged to design innovative systems that meet higher industrial standards. New generations of coatings attempt to improve features like drying speed, durability, corrosion resistance as well as color, performance and appearance. Waterborne epoxy formulations, however; require even more attention with respect to additive utilization as by nature their polymer structure is quite sensitive to many typical ingredients of additives. We have, therefore; designed a series of new additives that can be easily formulated to improve the overall performance of waterborne epoxy resin formulations. As example, our latest generation of “low ion migration – LIM” based pigment wetting & dispersing additives provide improved anti-corrosive performance.
