This process is faster and involves only one stage. As the name suggests, fatty acids along with polyol and dibasic acid are reacted in a single step via direct esterification. This process gives more latitude for selection of polyol component and is useful when polyols other than glycerol are to be used in a formulation. Also, this process gives better control over MW, MW distribution and acid number, which gives a better product in a shorter processing time. Therefore,

despite the higher cost of fatty acids, this process is widely used in the industry, especially in high-solid resin applications.
