1,3-BUTYLENE GLYCOL IMPROVES POLYESTER RESINS AND POLYMERIC PLASTICIZERS

. . . also offers new advantages for producers of coating resins, printing inks, dyes and elastomers. Celanese 1,3-butylene glycol (1,3-BG) is a highly purified, 4-carbon diol. It is of particular interest in the preparation of resins for coating materials, laminates, potting compounds and plasticizers. Unsaturated Polyesters—By permitting the formulation of high molecular weight polyesters without ether groups, 1,3-BG produces resins with good resistance to chemicals and weathering, good flexibility and impact resistance. Its relatively high boiling point minimizes glycol loss during reaction. Resin solutions are unusually light in color. Saturated Polyesters—When used in polyesters for urethane coatings, 1,3-BG contributes to their flexibility, water-resistance and toughness. Polymeric Plasticizers—Adipate plasticizers based on 1,3-BG offer permanence; outstanding plasticizer efficiency; resistance to extraction by soapy

water, oil, gasoline and very good stability to heat and light. Humectant—Low toxicity and good hygroscopicity make 1,3-BG suitable for use as a humectant for cellophane, tobacco and paper. Intermediates—1,3-BG is used in conjunction with or as an intermediate in printing inks, pharmaceuticals and dyestuffs. Have you investigated the advantages of this versatile chemical?
