Polychloroprene has a long history in the world of adhesives. It has been the primary choice when fast, high-strength, and permanent bonds are needed in variety of applications, from shoe soles to foam bonding. Historically, polychloroprene adhesives have been solvent borne, but environmental and occupational safety reasons have recently caused a shift toward waterborne polychloroprene adhesives. One of the challenges in waterborne polychloroprene dispersion adhesives has been related to the thickening of these high pH systems, as well as the storage stability.

Sustainable bonding requires combining the highest possible certified bio-based raw material content in the adhesives, low maintenance and energy requirements in the bonding process, high compatibility of the adhesives with existing application systems, and, especially in the packaging industry, high compatibility in terms of downstream paper recycling. All of this must be achieved at competitive prices.
