Overwhelming penetration power! An adhesive that easily repairs concrete cracks.
"Crack Bonder" is a special polyurethane resin adhesive used for injecting into cracks in concrete structures with a dedicated gun and mixer nozzle. It has ultra-low viscosity and high penetration power, allowing it to seep into not only the cracked areas but also the air voids in the concrete, reinforcing the cracks through a "micro doweling effect" that creates a root-like bond. 【Features】 - Penetrates fine surface cracks and internal microcracks - Exhibits excellent adhesion even after repeated drying and wetting cycles post-injection - No need for installation of injection equipment or sealing materials like traditional injection methods → Enables quick construction and early release - Allows for easy and proper two-component mixing using the dedicated gun and mixer nozzle → Prevents curing failures - Surface tension is about one-third that of water → Penetrates fine cracks of less than 0.2mm where water cannot → Provides rust prevention for rebar For more details, please contact us or download the catalog.
