Prime Resins Prime Flex 940 polyurethane resin is a very low viscosity, hydrophobic resin that reacts with water and expands to form a closed cell, watertight flexible foam. This resin is used for sealing actively leaking joints and cracks in concrete structures, particularly those subject to movement or vibration. It is verified to meet NSF/ANSI Standard 61.5 for contact with potable water. The foam’s flexibility allows it to expand and contract along with the structure it has sealed, so it remains watertight despite temperature fluctuations or minor movement. Its low viscosity makes it suitable for hairline cracks. 10:1 "Quick Mix" Cartridge
