Prime Flex Hydro Gel SX 970 5gl Pail

Prime Flex Hydro Gel™ SX polyurethane resin

Prime Flex Hydro Gel™ SX is a versatile, easy-to-use single-component, water activated, hydrophilic polyurethane injection resin for sealing actively leaking joints and cracks in below-grade concrete structures. It forms either a closed cell, watertight foam or impermeable gel depending on the water to resin mix ratio. Cured material remains flexible and has excellent adhesion. It can also be used for soil binding for slough control. Independently tested and verified to meet NSF/ANSI Standard 61 for contact with potable water.
