The first field applicable PVDF coating that blocks dissolved salts ions and corrosive acidic gases from weakening of the concrete buildings and infrastructure.

PRINCETON JUNCTION, NJ, UNITED STATES, May 30, 2023/EINPresswire.com/ -- AIT Coating Division of AI Technology, Inc. is proud to introduce the world’s first field applicable PVDF concrete weakening protection coating at the 2023 AIA Architecture Show (booth 4219) at Moscone Center, San Francisco, CA on June 8-9, 2023.

Why does seemingly indestructible concrete buildings and infrastructure need a protective coating?
The collapse of the Florida Surfside Condominium on June 24, 2021, is a wake-up call for the building industry. The weakening of the concrete structural strength by chemical reactions inside the concrete and corrosion of the rebars by environmental moisture laden with dissolved salts and corrosive gases, is like “cancer” of concrete. The weakening of the structure due to the slow degradation processes inside the concrete are not always obvious from traditional inspection methods.

Why is FLUOROSEAL^® PVDF concrete protection coating the best choice for protecting existing buildings and infrastructure from further weakening?
To be effective in protecting concrete buildings and infrastructure from corrosion weakening, the solution must not only have measurable or incremental improvements but must be indisputable in effectiveness in stopping further weakening by:
1. Blocking moisture laden with corrosive ionic salts and corrosive acidic solutions from passing through the concrete and causing rebar corrosion weakening and stress.
2. Blocking corrosive gases such as H2S, SO2, CO2, NO, CL2 from penetrating the encasing concrete. These gases cause concrete carbonation-alkalization weakening and steel rebar corrosion.
3. Preventing freeze-thaw induced expansion, causing delamination and concrete fractures, by blocking penetration of moisture/water at concrete-rebar interfaces and concrete pores.
4. Blocking UV from degrading acrylic, stucco, epoxy and/or polyurethane structural coatings. UV molecular disintegration of these coatings accelerates the penetration of corrosive elements that cause steel rebar corrosion and concrete chemical reactions.

FLUOROSEAL^® concrete and corrosion protection coating is a modified PVDF polymer. PVDF is well known for its ultra-low permeability to moisture and corrosive gases. This property provides 3-5 orders higher effectiveness in blocking moisture-water with dissolved salt ions and corrosive gases from penetrating inside the concrete.
• FLUOROSEAL^® PVDF corrosion protection coating also maintains its intrinsically 1-2 orders of magnitude lower moisture-water absorption and retention, blocking off concrete chemical reactions and rebar corrosion.
• FLUOROSEAL^® PVDF concrete and corrosion protection coating is a single component, VOC-exempt solution that can be roller, brush or spray coated onto bare concrete for immediate protection. It is dry to the touch in less than an hour and effective for protection. It can also be re-applied anytime as needed.
• FLUOROSEAL^® PVDF coating provides an immediate effective sealing barrier to protect the concrete and rebar structure as applied. For existing buildings and infrastructure, stopping further concrete weakening is the best solution for safeguarding the property and safety of the occupants.
• The intrinsic UV resistance and stability of FLUOROSEAL^® PVDF is far better than other polymer coatings of epoxy, polyurethane, acrylic and silicones.
• PVDF coatings have a proven record of effectiveness under the Florida sun for 60+ years. FLUOROSEAL^® PVDF concrete and corrosion protection coating seals against moisture and corrosive gases and offers similar chemical and physical properties providing similar longevity and effectiveness.

Garage Buildings and Vehicle Tunnels are more Vulnerable with Heavy Corrosive Exhaust Gases that can Benefit Most from the FLUOROSEAL^® PVDF concrete and corrosion protection coating:
Similar to the underground and lower car park levels of high-rise buildings, parking garages and tunnels for vehicle traffic, concrete infrastructures are exposed to higher amounts of corrosive gases such as CO2, H2S, SO2, CL2 and also typically more humidity. Undersea tunnels and tunnels located in temperate and colder zones during winter months, are exposed to salt-fog and spray with dissolved salt ions that penetrate inside the concrete and collect at rebar-concrete interfaces, thus accelerating the concrete chemical reactions and rebar corrosion, resulting in weakening of the reinforced structure and requiring frequent expensive repairs.
