DUOTACK SPF HFO Adhesive is a two-component, low-rise spray polyurethane foam (SPF) adhesive that now features a hydrofluoroolefin (HFO) blowing agent that makes it significantly better for the environment while enhancing its performance for adhering fleece-back membranes, insulation and coverboards.

The blowing agent has a very low global warming potential—only 0.1% that of a hydrofluorocarbon (HFC). A trigger-lock dispenser with stop and start capability prevents waste. DUOTACK’s ColorWise Temperature Warning Nozzles change from clear to blue if the product is too cold to be applied properly.
