Waterborne products

Today, the civil engineering and coatings industries are without any doubt convinced of the advantages of using waterborne epoxy systems: these systems are environment‑friendly, they offer enhanced work comfort (less smell) and reduced toxicity for the applicators working in closed areas. They are not flammable, they allow for easy cleaning of the application tools with water. These systems also do exhibit excellent adhesion on concrete and on humid surfaces, and they can even be used on wet concrete.

However, formulators are still reluctant to switch to waterborne epoxy binders because they still encounter problems using those:

waterborne systems tend to cure slowly; their application thickness is often limited; the final gloss of cured coatings is also known to be poor, because of an imperfect film formation process. Finally, the protective efficiency of aqueous epoxy formulations, in particular on metal, is regularly questioned and does not always attain the performances achieved by their non-aqueous counterparts.

In QR-Polymers, we believe we can offer waterborne curing agents which address these concerns. Through R&D and close cooperation with our customers, we are continuously improving and expanding our product range to meet today and tomorrow market requirements.
