Water-reducible polyesters

After carrying out the reaction to the appropriate acid number, the water-reducible polyester is dissolved in an ether-alcohol such as l-propoxy-2-propanol [1569-01 -3] secondary alcohol should be used because primary alcohols lead to more rapid transesterification than... 

Such polyurethanes have excellent hydrolytic stability compared to water-reducible polyesters and superior abrasion resistance. In view of the importance of developing low solvent emission coatings, considerable effort is being devoted to new types of water-borne urethane resins (62,63).

Because of the water-solubility of HMMM resins, they can be used with water-reducible alkyds, polyesters or acrylics and with acrylic copolymer latices to produce water-based counterparts of the above stoving finishes. While the reduction in solvent is substantial, such coatings are not usually free of small proportions of water-miscible cosolvents, e.g. 2-butoxy ethanol, and ammonia or amines (pp. 119, 120). An example of a water-reducible polyester-MF stoving finish is given in Table 13.5.
