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.

As part of its roadmap to become a leading sustainable business, Fedrigoni Group has announced that its Fedrigoni Self-Adhesives division plans to increase the volume of advanced ESG solutions in its product portfolio from 35% to 70% by 2030.

In collaboration with ChileGlobal Ventures, the venture capital arm of Fundación Chile, Henkel Chile has launched the global Seal the Cycle initiative to find technological solutions for plastic waste. The goal of the initiative is innovation in separating high-density polyethylene (HDPE) from silicone waste to enable the recycling of cartridges that cannot currently be reprocessed.

Henkel has introduced three new low-pressure molding (LPM) materials designed to seal and protect medical devices from moisture, temperature extremes, chemicals, vibration, impact, and other environmental concerns.

Dow recently announced that Mary Draves, vice president of Environment, Health and Safety (EH&S) and chief sustainability officer, has announced her decision to retire in April 2022, following more than 32 years of service with the company.

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.
