About Fosroc Nitobond EP Epoxy Bonding Agent 4L
- For bonding fresh wet cementitious materials to existing cementitious surfaces.
- For use on horizontal or vertical surfaces where mortar or concrete can be supported by formwork.
- The product is ideal for roads, bridges, pavements, loading bays and factories, and for bonded or granolithic floor toppings.
- Nitobond EP is equally suited to internal and external applications.
- Nitobond EP may also be used as part of a repair system where a substrate/repair barrier is required or where the repair/ substrate is likely to become immersed, permanently wet or damp subsequent to the completion and cure of the repair.
Superior Structural BondingFosroc Nitobond EP delivers robust adhesion between old and new concrete, steel, bricks, and masonry. Its advanced epoxy formula ensures a reliable connection where structural performance is paramount. Suitable for a range of applications, it excels in repair, patching, and strengthening projects across civil, industrial, and flooring installations.
Easy Mixing and ApplicationWith a straightforward 2:1 mix ratio by weight (base to hardener) and a generous pot life of approximately 90 minutes at 20C, this bonding agent offers plenty of time for precise placement. The light grey, two-component system is designed for convenience, allowing efficient handling for both large and small repairs.
Long-Lasting and Durable ResultsAfter initial curing in 6-8 hours at 20C and full curing in 7 days, Nitobond EP achieves outstanding mechanical strength (over 70 MPa compressive strength). Its low water absorption ensures longevity in harsh environments, making it well-suited to high-traffic and demanding industrial or engineering settings.
FAQ's of Fosroc Nitobond EP Epoxy Bonding Agent 4L:
Q: How should Fosroc Nitobond EP Epoxy Bonding Agent be mixed and applied?
A: Mix the base and hardener at the recommended 2:1 ratio by weight using a slow-speed mixer until a consistent, light grey blend is achieved. Apply the mixture directly onto a clean, prepared substrate using a roller or brush within the 90-minute pot life at 20C. It is important to adhere to the application temperature range of 5C to 35C for optimal bonding.
Q: What types of surfaces or materials can this bonding agent be used on?
A: Fosroc Nitobond EP is formulated for bonding old concrete to new concrete, steel to concrete, masonry, and bricks. It is suitable for structural repairs, patchwork in civil engineering, and industrial flooring, ensuring secure adhesion across a variety of construction materials.
Q: When can overlying concrete or materials be placed after applying Nitobond EP?
A: Once you have applied Nitobond EP to the substrate, new concrete or repair material should be placed while the bonding agent is still tacky-within its pot life and before it fully cures, typically within 6-8 hours at 20C.
Q: Where should Nitobond EP be stored to maintain its shelf life?
A: Store unopened containers in a dry, cool area, away from direct sunlight. Under these conditions, Nitobond EP maintains a shelf life of 12 months, ensuring consistent performance when needed.
Q: What benefits does Fosroc Nitobond EP offer in structural repair projects?
A: Nitobond EP provides high bond and compressive strength, leading to concrete failure before bond failure (>3.0 MPa bond strength). Its fast initial cure, minimal water absorption, and resistance to chemical and mechanical stress make it ideal for lasting repairs in demanding environments.
Q: What is the full curing time and why is it important to wait for it?
A: The full cure time for Nitobond EP is 7 days at 20C. Waiting for the complete curing process ensures the adhesive reaches maximum strength and durability, providing a long-lasting bond that can withstand high stresses and environmental exposure.
