Concrete cracks are physical structural changes caused by internal and external factors acting on concrete structures. Cracks are the main cause of reduced bearing capacity, durability and water resistance of concrete structures. Different treatment methods are usually adopted according to different types of cracks.
This epoxy resin crack repair adhesive is a two-component (A/B) modified epoxy-based low-viscosity liquid adhesive.
Low viscosity, low heat release, long pot life and simple grouting process.
Capable of penetrating microcracks as narrow as 0.1mm.
Excellent aging resistance and resistance to media (acid, alkali, water).
Free of volatile solvents; no shrinkage during curing.
