  • The Future of Waterborne Alkyd Coatings


    Alkyd coatings are used in many industrial and architectural applications due to their unique properties. Manufacturing waterborne alkyds rather than solvent-based alkyds is a growing trend. We understand that manufacturers want the good qualities of a solvent-based alkyd with no drop off in performance when converting it to a waterborne alkyd. The use of Ethox’s reactive emulsifiers can help bridge the gap in performance of your waterborne alkyd coating. Continuing with our previous newsletter theme of waterborne alkyd coatings, we have provided a free download with some of the testing and performance results that were observed with the use of our E-Sperse® RX Series reactive emulsifiers in a waterborne alkyd coating.
