Epoxy Bonding Agent
Two-component structural epoxy bonding agent for permanent old-to-new concrete bond.
Overview
Structural-grade bond. Stronger than the parent.
Epoxy Bonding Agent is a two-component, solvent-free epoxy for structural connection of new concrete or mortar to existing hardened concrete. The cured film has tensile and shear bond strengths that exceed the parent concrete.
Essential for any repair where the bond interface will be subject to tensile, shear, or vibration loads. Specified per ASTM C881.
Key Features
- Two-component structural epoxy – 100% solids
- Bond strength exceeds parent concrete
- ASTM C881 Type V certified
- Solvent-free – no shrinkage
- Compatible with wet and dry substrates
- Tolerates wide range of substrate conditions
