| Résumé : |
A new waterborne, modified solid epoxy resin dispersion with good flexibility and improved shear stability is presented. When this binder is used, high performance metal primers can be formulated without the use of anti-corrosion pigments. This is highly desirable since the toxicological effects of zinc phosphate and other zinc-based salts are causing environmental concerns. Primers formulated with this new resin provide equal or better corrosion resistance
when compared to a number of waterborne and solventborne paint formulations, some of which contain anti-corrosion pigments.
Other advantages can also be obtained, including the possibility of formulating metal primers with VOC contents less than 100g/L. In addition, direct pigment grinding is possible under processing conditions typical for other standard waterborne epoxy dispersions. |
