Odorless Water-Dispersible Sulfopolyester for Adhesive Formulations, 2000 Hot Melt Symposium Proceedings
Richard A. Miller--Bonding with hot-melt adhesives poses some unique requirements to maintain bond integrity under a variety of end uses. The hot-melt adhesive industry has desired a water-dispersible raw material for a considerable amount of time. Branched sulfopolyester represents a “best of both worlds” approach where water-dispersibility is provided, along with other unique attributes, without sacrificing the key application/performance profiles that the adhesive industry requires. Some polyester raw materials have a distinct odor that is not desirable for selected applications. In response to this need Eastman Chemical Company developed a odorless water-dispersible AQ sulfopolyester. The properties and a statistically designed experiment of adhesive performance characteristics of this water dispersible polyester will be described in this paper.
