Hyperdesmo® HAA is a unique single-component polyurethane liquid membrane, based on the successful combination of Hyperdesmo and Accelerator 3000 which throughout the years has provided applicators with a solution for a fast curing, bubble-free thick layer membrane. Our commitment to research and development combined with our investment and efforts to continuously upgrade our chemical processing plant has allowed us to formulate a Hyperdesmo® with the Accelerator 3000® incorporated in a blocked fashion, that upon contact with humidity is released and self-accelerates the curing of the material in a similar manner as the Accelerator 3000®.
