Water dispersible hot-melt adhesive formulations

Repulping of paper products has created a need for hot-melt adhesives that are water- dispersible. Eastman Chemical Company has developed a family of branched, water dispersible polyesters suitable for formulating repulpable hot-melt adhesives. These materials offer the following key benefits when formulated into hot-melt adhesives: 100% WATER DISPERSIBLE POLYMERS REPULPABLE UNDER NEUTRAL AND ALKALINE CONDITIONS WIDE RANGE OF VISCOSITIES FDA APPROVED, INDIRECT FOOD CONTACT EXCELLENT ADHESION TO POLYOLEFIN FILMS NON-IRRITANT, ON TSCA LISTING NON-DISPERSIBLE IN BODY FLUIDS COMMERCIALLY AVAILABLE Starting point formulations for water dispersible adhesives based on the branched polyesters have been identified for use in the following application areas: carton/case closing, multi-wall bags, nonwovens, PET bottle labeling, and pressure sensitive adhesives.
