Cortec MCI® Construction Film

Introduction

Cortec MCI® Construction Film is a multi-layered, high-performance film that combines the strength and durability of traditional construction films with the advanced corrosion-inhibiting properties of Cortec’s proprietary MCI technology. This innovative product is designed to provide a robust barrier against the elements, while actively working to prevent the onset of corrosion in reinforced concrete structures.

Unlike conventional plastic films and conventional films, which may lead to corrosion where metal surfaces come into contact, Cortec MCI® Construction Film incorporates advanced technology that inhibits corrosion, making it a superior alternative.

At its core, Cortec MCI® Construction Film is composed of a unique blend of materials, including high-quality polyethylene and the company’s patented MCI additives. These additives are formulated to migrate through the concrete, forming a protective layer around the embedded steel reinforcement. By creating a corrosion-inhibiting environment, the film effectively safeguards the structural integrity of the concrete, extending its lifespan and reducing the need for costly repairs.

How it works

The secret to Cortec MCI® Construction Film’s effectiveness lies in its Migratory Corrosion Inhibitor (MCI) technology. This innovative approach to corrosion control is based on the principle of migrating corrosion inhibitors, which are designed to travel through the concrete matrix and reach the reinforcing steel. The film is specifically designed to inhibit corrosion on metal surfaces, providing a protective barrier and enhancing the longevity of structures.

As the MCI additives within the film migrate, they form a protective molecular layer on the surface of the steel, creating a barrier against the intrusion of corrosive elements such as chlorides, carbon dioxide, and moisture. MCI film inhibits corrosion on both direct contact surfaces and nearby metal parts through vapor phase inhibitors. This proactive approach to corrosion prevention helps to maintain the structural integrity of the concrete, ensuring that the reinforcing steel remains protected and the overall lifespan of the structure is extended.

Applications of Cortec MCI® Construction Film

Cortec MCI® Construction Film is a versatile solution that can be utilised in a wide range of construction applications, from new building projects to repair and rehabilitation work. Its versatility and effectiveness make it an invaluable tool for architects, engineers, and construction professionals who are committed to delivering high-quality, long-lasting concrete structures. The film is particularly effective in protecting concrete and metal studs from corrosion, enhancing the longevity of the structure. Additionally, it is used in concrete forms to prevent build-up and corrosion, ensuring smooth operation and protection of metal surfaces.

Some of the key applications of Cortec MCI® Construction Film include:

New Construction Projects

In new construction, the film can be used as a protective barrier during the pouring and curing of concrete, shielding the reinforcing steel from the elements and preventing the onset of corrosion from the very beginning. Additionally, the film protects both ferrous and non-ferrous metals during these stages, ensuring comprehensive protection against corrosion.

Repair and Rehabilitation Work

For existing concrete structures that have experienced deterioration or corrosion, Cortec MCI® Construction Film can be applied as a part of the repair and rehabilitation process, effectively halting the progression of corrosion and restoring the structure’s integrity. Additionally, using surface applied corrosion inhibitors, such as MCI®-2018 and MCI®-2020, can enhance protection by significantly slowing down corrosion rates and preserving structural integrity.

Specific Use Cases

The film’s versatility extends to a variety of construction applications, including bridges, highways, parking structures, marine environments, and industrial facilities, where corrosion protection is of paramount importance. In these settings, the use of corrosion inhibiting admixture in concrete mixes or as coatings ensures enhanced protection for embedded rebar and metal structures against corrosion.
