PHUREX INJECTION 1K is a ready-to-use, singlecomponent polyurethane-based injection resin with an integrated catalyst/accelerator system. Thanks to its low viscosity, it penetrates quickly and deeply into fine cracks, joints, voids, and capillary channels in concrete, stone, brick, and similar mineral-based building materials. Since the product does not require any additional mixing of components or the addition of a catalyst during application, it can be applied directly with a singlecomponent injection pump.
