Hollowing, cracking and peeling diseases of building structures are invisible killers that threaten the safety and durability of buildings. The hollow series epoxy adhesive developed to address this stubborn problem has developed from a simple repair material into a systematic structural repair solution, playing an indispensable role in the renovation of old cities, the protection of historical buildings and the maintenance of large infrastructure.

The core technology of this series of products lies in its "low viscosity, high penetration, and strong anchoring" characteristics. In order to achieve this goal, formulation engineers carefully selected and compounded the epoxy resin and curing agent system. The combination of low molecular weight epoxy resin and reactive reactive diluent ensures that the glue penetrates into tiny cracks and cavities without blind spots and reaches the root of the disease. At the same time, the use of modified amine curing agents allows the colloid to be fully cured even on wet concrete base surfaces or at lower ambient temperatures, forming a chemical bond as strong as the base rock, and its bonding strength often exceeds the tensile strength of the concrete itself.

Modern hollow drum repair projects are far from simple filling with glue. The supporting special low-pressure injection equipment, precise hole position design and pressure control technology constitute a complete "diagnosis-treatment-verification" technical system. Construction workers can use this series of adhesives to not only effectively fill empty drums and restore structural integrity, but also bridge micro-cracks through pressure injection to prevent further corrosion of steel bars and significantly extend the life of the structure. In recent years, this series of products has developed more towards environmental protection and intelligence. The introduction of solvent-free, low-odor formulas meets the stringent requirements for construction in indoor and sensitive environments; and the intelligent adhesive mixed with fillers can continuously monitor the stress and strain status of the repair area after curing, achieving long-term online monitoring of structural health. From old residences to cross-sea bridges, hollow series epoxy adhesives are silently guarding the safety bottom line of the human built environment with their excellent reliability and evolving technical connotations.
