Cortec MCI® 2019 FD: The Freeze-Dried Alternative

While Cortec MCI® 2019 has proven to be a highly effective solution, the company recognised the need for an even more versatile option. This led to the development of Cortec MCI® 2019 FD, a freeze-dried version of the original product.

Cortec MCI® 2019 FD offers several unique advantages:

• Increased shelf life: The freeze-dried formulation allows for extended storage and shelf life, making it a more convenient choice for construction projects with longer timelines.
• Reduced shipping costs: The compact, lightweight nature of the freeze-dried product reduces transportation costs, making it a more cost-effective solution for projects in remote or hard-to-reach locations.
• Simplified mixing: Cortec MCI® 2019 FD can be easily reconstituted on-site by simply adding water, reducing the need for specialized equipment or complex mixing procedures. The inclusion of a fugitive dye enhances visibility during application.

Proper application of Cortec MCI® 2019 FD is crucial for achieving optimal results, as the product's effectiveness relies on following precise and proper application and methods.

How Cortec MCI® Products Work: Monomolecular Corrosion Inhibiting Coating

The Migrating Corrosion Inhibitor (MCI) technology at the heart of Cortec MCI® 2019 and Cortec MCI® 2019 FD is a revolutionary approach to corrosion protection. These products work by forming a protective molecular layer on the surface of the embedded steel reinforcing bars, preventing the initiation and progression of corrosion. This is achieved through the migratory corrosion inhibitor action, which allows the inhibitor to move through dense concrete and effectively protect embedded steel reinforcing bars by forming a protective coating.

The active ingredients in Cortec MCI® products are designed to migrate through the concrete, reaching the embedded steel reinforcement and creating a monomolecular corrosion inhibiting coating that shields it from the damaging effects of chlorides, carbon dioxide, and other corrosive elements. This proactive approach to corrosion management helps to extend the service life of concrete structures, reducing the need for costly repairs and maintenance.

Additionally, these products perform effectively in an alkaline environment, ensuring comprehensive protection even in the high pH conditions typical of concrete.

Benefits for Existing Concrete Structures in Construction Projects

The use of Cortec MCI® 2019 and Cortec MCI® 2019 FD in construction projects offers a range of benefits, including protection against moisture intrusion:

• Extended Service Life: By effectively mitigating corrosion, these products help to extend the lifespan of concrete structures, reducing the need for premature replacement or extensive repairs.
• Cost-Effectiveness: The long-term cost savings associated with reduced maintenance and extended service life make Cortec MCI® products a highly cost-effective solution for construction projects.
• Environmental Sustainability: As water-based, VOC-free formulations, Cortec MCI® products align with the growing demand for environmentally responsible construction practices.
• Versatility: The availability of both standard and freeze-dried versions of the product allows for greater flexibility in application and logistics, making Cortec MCI® solutions suitable for a wide range of construction projects while maintaining the original appearance of the concrete.
• Application Methods and Best Practices to Prevent Moisture Intrusion

Cortec MCI® 2019 and Cortec MCI® 2019 FD can be easily applied to new or existing concrete structures using a variety of methods, including spray, brush, or roller application. Treated substrates become hydrophobic while preserving their original appearance, indicating effectiveness against moisture intrusion and corrosion. It is important to follow the manufacturer’s recommended surface preparation and application guidelines to ensure optimal performance.

When applying Cortec MCI® products, it is crucial to adhere to all safety precautions, including the use of appropriate personal protective equipment (PPE) and proper ventilation. Detailed instructions and safety information are provided by Cortec Corporation to ensure a safe and successful application process.

Case Studies and Real-World Examples

Cortec MCI® products have been successfully implemented in a wide range of construction projects, demonstrating their effectiveness in protecting concrete structures from corrosion. Several case studies and real-world examples showcase the impressive performance and long-term benefits of these innovative solutions.

One notable case study involves the use of Cortec MCI® 2019 in the restoration of a historic bridge in the United States. The bridge, which had suffered from significant corrosion damage, was treated with Cortec MCI® 2019, resulting in a significant extension of its service life and a substantial reduction in maintenance costs.

Another example highlights the use of Cortec MCI® 2019 FD in a remote construction project in a developing country. The freeze-dried formulation's ease of use and reduced shipping requirements proved invaluable, allowing for a successful and cost-effective application of the corrosion protection solution.

Comparison with Other Corrosion Protection Methods

Traditional corrosion protection methods, such as the use of epoxy coatings or cathodic protection systems, have their own limitations and drawbacks. These methods often fail to effectively manage electrochemical reactions that lead to corrosion. Cortec MCI® products specifically developed to offer a more comprehensive and cost-effective solution by addressing the root cause of corrosion through their unique Migrating Corrosion Inhibitor technology.

A detailed cost-benefit analysis demonstrates the long-term advantages of Cortec MCI® products, including reduced maintenance requirements, extended service life, and lower overall project costs. This makes them a compelling choice for construction projects that prioritize sustainability, durability, and cost-effectiveness.
