Discover H.B. Fuller’s new commercial roofing adhesive built for smarter performance and cleaner impact. 

For 130 years, we at H.B. Fuller have been committed to perfecting adhesives, sealants and other chemical solutions that answer global challenges. That’s why we’re excited to share Millennium PG-1 EF ECO₂, a new commercial roofing adhesive that sets a new standard for how industry professionals approach roofing applications, processes, performance and environmental impact. Millennium PG-1 EF ECO₂ uses our patented ECO₂ Driven™ technology, offering a forward-thinking solution for improved efficiency and a reduced carbon footprint for roofing applications across the world. 

A breakthrough in roofing adhesive technology 

Millennium PG-1 EF ECO₂ is the first commercial roofing adhesive to feature H.B. Fuller’s patented ECO₂ Driven™ propellant technology. Instead of relying on harmful high Global Warming Potential (GWP) propellants, hydrofluorocarbons (HFCs) or hydrofluoroolefins (HFOs), this adhesive uses naturally occurring atmospheric gases to deliver consistent high-performance with reduced environmental impact. 

This makes Millennium PG-1 EF ECO₂ compliant with current environmental standards and looks forward at the tightening global regulations on greenhouse gases. It's a forward-thinking solution for contractors who want to meet their sustainable building goals. 

Equipment-free application saves time and reduces waste 

The "EF" in the product’s name stands for "equipment-free," a key feature that streamlines the application process. Contractors can apply the low-rise, two-component polyurethane foam adhesive directly from a portable, dual-canister system without any heavy or expensive equipment. 

Each kit includes an applicator, hoses and static mixers capable of both ribbon and spatter applications. The simplified setup and portability make it ideal for hard-to-reach areas and fast-paced job sites. Furthermore, the canisters are recyclable when properly emptied, supporting waste reduction initiatives on the job site. 

Designed for high performance and versatility 

Millennium PG-1 EF ECO₂ is engineered to deliver top-tier performance in a wide range of roofing applications. Key benefits include: 

• Fast skin time: Sets in just five to eight minutes in ideal conditions, enhancing project speed and efficiency. 
• Wide substrate compatibility: Bonds to wood, steel, PolyISO, EPS, XPS, gypsum boards, mineral wool and more. 
• Thermal bridging reduction: Eliminates the need for mechanical fasteners, helping preserve the integrity of the roofing assembly while preventing moisture intrusion, reducing thermal inefficiency and maximizing R-values. 
• Low VOC emissions: VOC content under 50 g/L supporting compliance with environmental regulations and improving jobsite air quality, including those set by the South Coast Air Quality Management District (SCAQMD). 

This adhesive is ideal for use in data centers, cold storage facilities, schools, hospitals and other environments where jobsite and energy efficiency are top priorities. 

Supporting a sustainable roofing industry 

As the world's largest pureplay adhesives company, H.B. Fuller has long been at the forefront of innovation in adhesives and sealants. Millennium PG-1 EF ECO₂ is a testament to the company’s commitment to innovation, environmental sustainability, regulatory readiness and product excellence. 

With its unique combination of zero high-GWP propellants, equipment-free design and superior bonding power, Millennium PG-1 EF ECO₂ is more than a product. It's a solution built for the next generation of roofing.
