PRODUCT PROPERTIES:
- Modified polyurethane resin with high durability and flexibility.
- Ideal for application by injection method.
- Adjustable reaction time allows for easier application.
- Displaces water from infiltrated structures.
- Controlled expansion when reacting with water (forms rigid foam).
- Provides reliable waterproofing performance.
- Excellent compressive and tensile strength.
AREAS OF APPLICATION:
- Sealing and strengthening of cracks and voids in structural concrete, load-bearing brick walls, natural stone, etc., in civil, industrial, and hydraulic construction projects.
- Sealing of construction pits.
- Soil, rock, and foundation reinforcement beneath structures.
- Enhancing load-bearing capacity of underground slabs or slabs in contact with soil.
- Sealing and reinforcement of construction joints by increasing load transfer to the subsoil.

APPLICATION ADVICE:
- Preparation: Prior to injection, inspect the cracks and defects in the structure following applicable standards and procedures. Prepare a comprehensive execution plan. Use appropriate packers (e.g., MC-Stahlpacker 18/300) and install them in advance. Preliminary injection is recommended before full-scale application.
- Mixing:
– BF 2210 consists of Component A and Component B. The components are mixed thoroughly in the mixing head of a two-component injection pump (recommended length > 20 cm).
– Pot life depends on ambient temperature and can be extended by cooling the components and the mixed material.
- Reaction time adjustment: Setting and reaction time can be tailored to specific project requirements. MC-KAT 27 is an accelerator used to adjust the curing time (dosage up to 1%).
- Admixture: MC-Additive ST is used to adjust the foaming rate (recommended dosage: 4–7%). All admixtures must be added to Component A only.
- Application:
– BF 2210 should be applied using a high-pressure, two-component injection pump (e.g., MC-I 710).
– Recommended packer: MC-Bore Packer LS 18.
– Do not inject when the substrate or product temperature is below +5°C.
- Equipment cleaning:
– In case of long interruptions or upon completion, clean the pump thoroughly with a suitable cleaning agent, such as MC-Thinner PU or MC-Cleaner ECO.
– Hardened material on equipment should be removed mechanically (e.g., with a scraper or wire brush).
– Lubricating oil is recommended to protect the pump after use. Refer to pump manual for more information.
