For years, one of the most steadfast rules in the coating and lining industry was that applicators couldn’t coat over existing polyurea, after the “recoat window“, without the use of a primer or bonding agent. Getting proper adhesion between the old and new liners typically involved a manually intensive process and increased overall project cost. That is until Specialty Products, Inc. (SPI) threw that rule out the window with the Ultra Bond-100™ product, making what was once virtually impossible a reality.
Ultra Bond-100™ is 100% solids with no solvents or volatile organic compounds (VOCs), exhibits excellent chemical resistance, allows for a fast return to service and can be applied in ambient temperatures ranging from -20 to 100 degrees Fahrenheit. However, unlike other polyureas, Ultra Bond-100™ does not require labor-intensive surface prep – a clean, dry surface that is free of oils and debris is all that is required. And, in many instances, no primer is needed.
