Features
- Excellent bond strength for long-lasting repairs.
- High elastic modulus, ensuring effective stress transfer at the bond interface.
- Pre-measured components for consistent performance.
- Low viscosity, making it suitable for grouting fine cracks.
- Resistant to a wide range of chemicals and liquids.
Applications
EP 320 is suitable for a variety of crack repair and sealing applications in concrete structures. It can be used to address both fine and wide cracks, cold joints, and other structural imperfections, making it a versatile solution for construction and repair projects.
Substrate Preparation
To ensure optimal adhesion, the concrete surface must be hard, sound, and free from dust, paint, lime coatings, plaster, curing agents, laitance, adhesive residues, and other contaminants. Prepare the area by drilling appropriate holes and fixing the necessary injection packers or nipples, ensuring the holes are free from debris. Seal the entire length of the crack using a suitable adhesive before proceeding with the injection.
Storage and Shelf Life
EP 320 has a shelf life of 12 months when stored in a dry place between 5°C and 30°C in its original unopened containers. Protect the product from frost, direct sunlight, and heat sources.
