Millennium PG-1 EF ECO2 is an equipment-free, canister-based sprayable adhesive that uses a patented blend of naturally occurring environmental gases as a blowing agent, eliminating the need for chemical alternatives.

H.B. Fuller (NYSE: FUL), the largest pureplay adhesives company in the world, announced today the launch of an innovative new technology that is driving change for commercial roofing installation and enhancing environmental responsibility. The H.B. Fuller Millennium PG-1 EF ECO2 is a high-performance roofing adhesive that eliminates the need for chemical blowing agents by using naturally occurring atmospheric gases. This powerful blend of gases called ECO2 Driven™ technology, operates without the use of high Global Warming Potential (GWP) propellants or Hydrofluoroolefins (HFOs), reducing the environmental impact of dispensing the adhesive without compromising adhesion strength.

Designed to meet or exceed current North American environmental standards and align with emerging global regulations for Commercial Roofing, Millennium PG-1 EF ECO2 is easy to use, while supporting sustainability goals. Canister-based adhesives can help reduce job site waste as canisters offer significant coverage area per unit and, when properly emptied, can be recycled depending on local regulations.

“H.B. Fuller is committed to creating innovative solutions that make everyday products cleaner, faster, and more effective,” according to SuAnne Stevens, global vice president, commercial roofing. “Pairing this adhesive delivery method with the ECO2 Driven technology results in a contractor-friendly solution that considers not only the environment but also the overall working conditions for the installer.”

As with the first-generation Millennium PG-1 EF ECO product, the “EF” stands for equipment-free. This two-part low-rise foam adhesive efficiently combines part A with part B dispensed through two canisters and features a unique spray nozzle that quickly and easily transitions between a ribbon or spatter spray. This enables the installation of insulation board and fleece-backed roofing membranes with one product that is easy to use and transport.

In addition, compared to the mechanical fastening of roofing membranes, adhesives eliminate thermal bridging, achieve high wind uplift ratings, and minimize risks of leaks and building damage during re-roofing. These benefits support H.B. Fuller’s commitment to both innovation and sustainability.

With industry-leading performance and patented ECO2 Driven™ technology, Millennium PG-1 EF ECO2 helps customers achieve their operational and sustainability goals while delivering value to roofing contractors and building owners.
