The concept of value engineering is not only for the construction phase. It is also a useful practice during the maintenance and repair stages of existing reinforced concrete structures, ensuring projects get done within budget. True value engineering saves money without reducing service life or affecting the quality of construction or materials. Ideally, it adds value to the project. MCI^®-2019 is one such value engineering solution to take advantage of when seeking to extend the service life of existing concrete structures.

The Benefit of MCI^® Water Repellents

MCI^®-2019 is a 40% silane, solvent-based concrete water repellent containing Migrating Corrosion Inhibitors. The small molecules of MCI^®-2019 can easily penetrate into concrete, providing water repellency by chemically reacting with cementitious substrates under proper application. MCI^®-2019 seals surface pores, which prevents intrusion of chloride and carbonation and protects from the ingress of wind driven rain. Treated areas retain their original appearance and are breathable. MCI^®-2019 is an excellent option both as the finishing touch on a concrete repair (where no membrane or coating system is used) and for periodic maintenance every 7-10 years. Since MCI^®-2019 increases service life, it can ultimately reduce the use of repair or reconstruction materials, thus contributing to sustainability.

Coping with Silane Shortages

One of the big challenges for the construction industry and many others today is the issue of raw material shortages (consequently driving the cost of materials up). For instance, silane supplies are often delayed or difficult to find. Using only a 40% silane relaxes the demand and helps the supply go farther while still providing a significant degree of water repellency. Since MCI^®-2019 contains Migrating Corrosion Inhibitors that provide active corrosion protection at the rebar, the need for 100% silane is also not as strong because a dual mechanism is at work to keep corrosives out and resist those that do find their way in.

Cutting Costs

In addition to working around supply chain shortages, MCI^®-2019 is also a great way to help cut costs when working on a limited budget. This is especially true with the current combination of supply chain shortages and inflation driving up the price of silane even farther. Using MCI^®-2019 saves costs compared to similar alternative systems. It can help a project stay within budget while still offering an excellent source of corrosion protection.

Saving Labor Time and Intensity

Another way MCI^®-2019 can save costs is simply by requiring less labor than other water repellents and surface applied corrosion inhibitors (SACIs). Silane wears out and erodes over time, so a good maintenance practice is to reapply it at 7–10-year intervals to maintain concrete water resistance and simultaneously add another dose of SACIs. Usually, workers water-blast the surface to make sure the silane residual is completely cleaned off and then apply a new SACI and a 100% silane water repellent. However, with MCI^®– 2019, this may be unnecessary. Workers can save time by applying one or two coats of a two-in-one product and leaving the old silane in place. The silane in MCI^®-2019 supplements any residual silane, while Migrating Corrosion Inhibitors are still able to penetrate into the concrete. A further advantage is that MCI^®– 2019 does not etch, stain, discolor, or otherwise harm glass or aluminum.

Repair of University Towers

In 2015, three 1970’s cast-in-place concrete residence towers at a Midwestern university required repair due to rusted rebar in concrete. After using MCI^®-2019 instead of a standard 40% solids silane water repellent post repair, the project’s specifying engineer commented, “MCI^®-2019 provided a cost-effective solution in applying both a migrating corrosion inhibitor and a silane sealer in a single product in one application with no resulting color change to concrete façade[s].” The non-etching feature was crucial to the protection of the structure’s new windows, and the parties involved were happy with the ease of MCI^®-2019 application.

Be Ready with Multiple Value Engineering Solutions

In today’s market, it is important to have many different value engineering options at one’s fingertips. MCI^®-2019 is one that can help engineers and contractors cope with silane shortages and stay within budget all while fortifying concrete with corrosion inhibitors to extend service life.

Each coating job has different priorities-whether convenience, corrosion protection, outdoor durability, or chemical resistance. In the first case, single-component, one-coat, direct-to-metal (DTM) coatings systems are great for applications that need quick protection without a lot of time to wait for primers and multiple coats to dry and cure. However, when time does allow, it is best to put in a little extra effort—using 2K products, primers, and multiple coats-in order to achieve the best coating performance possible. That is where VpCI®-395 comes in as Cortec’s first-class, 2K metal primer for corrosion protection!

Why Use VpCI®-395?
There are many great reasons to use VpCI®-395 Water-Based Epoxy Primer. For starters, VpCI®-395 is Cortec’s most durable anticorrosion primer. It not only promotes good surface adhesion between the metal and topcoats, but it also has greater strength as a 2K (two-component) primer. The extra effort that goes into mixing two parts together at the jobsite translates into greater durability because it allows crosslinking, i.e., greater chemical bonding, between the active ingredients in the primer. VpCI®-395 shows excellent performance in salt spray and humidity testing. In addition to promoting a stronger coatings system that inhibits corrosion, VpCI®-395 has the worker and environmental advantage of being water-based. Water-based coatings typically make cleanup easier and are often associated with lower VOCs (0.2 lbs/gal [24 g/L] in the case of VpCI®-395). Thus, VpCI®-395 reduces worker exposure to solvents both in the painting and cleanup process.

Where to Use VpCI®-395
VpCI®-395 is excellent for use in immersion applications and chemical plants because of the toughness of its epoxy. It can be applied as a primer inside tanks and on handrails and metal walkways. Indoors, VpCI®-395 can also be used as a topcoat (since UV resistance is not needed) and tinted to match the plant’s color scheme. Outdoors, VpCI®-395 can be combined with EcoShield® VpCI®-386 to create one of Cortec’s best water-based anticorrosion coatings system. It can also be used with a 2K urethane one-coat system such as VpCI®-384 for even greater durability if a water-based topcoat is not needed.

Going the Extra Mile for Coatings System Success
Often, the most difficult part of a job is the prep-work-whether surface prep, additional mixing, or extra effort to apply a primer. However, these tasks can offer invaluable payoffs in terms of adhesion and overall coating durability. In the case of VpCI®-395, the extra mixing of two components rewards users with a stronger primer to help maximize the success and corrosion protection of the entire coatings system. Next time your coating project can afford to go the extra mile for greater coating durability, be sure to contact Cortec® about VpCI®-395 Water-Based Epoxy Primer for a great start to your coatings system:
