Simplifies Production of High-Performance Waterborne Acrylic Polyols
Compliance with increasingly stringent VOC legislation and an increased awareness of the importance of environmental stewardship have driven the development of many new low-VOC coating technologies. Waterborne acrylic polyols for 2K urethane finishes have played an important role in enabling regulatory compliance in the industrial and automotive finishes markets, yet their synthesis can be difficult. This article introduces a simplified method for the production of high-performance solvent-free waterborne acrylic polyols, made possible by Cardura™ E10P glycidyl ester technology. The performance characteristics of coatings made with these waterborne polyols is also demonstrated and compared to a commercially available waterborne polyol with significant solvent content.
In the 1950s, Dr. Herbert Koch from the Max Plank Institute in Mülheim, Germany, found that olefins react with carbon monoxide and water under the influence of strong acids to form tertiary branched neocarboxylic acids (Figure 1). Before the intermediate carbocation reacts with carbon monoxide, isomerization reactions occur and, therefore, the resulting acid is composed of a number of isomers.1, 2
