VCIs as Alternative Corrosion Inhibitor Technologies

The use of vapor corrosion inhibitors in coating formulations has shown that in many systems, they can replace the older technology or significantly improve the performance of the system by working in synergy with the existing inhibitors.

Self-Healing Additives Boost Protective Coatings

The new additive system is comprised of a liquid healing agent encapsulated by a polymeric shell, which upon incorporation into a coating formulation can impart self-healing functionality to the coating. The formulation consists of an epoxy resin, a polar diluent, a corrosion inhibitor, and an adhesion promoter.

Hybrid Nanocoating Extends Life of Industrial Coating Systems

The single component, humidity cured, polyurethane/polyurea hybrid nanocoating penetrates into the pores and voids of new or highly oxidized paint systems to form a hard, protective topcoat surface.

Thixotropic Gel Halts Subsea Corrosion of Carbon Steel

The FlexGel range of products are designed to halt the corrosion of carbon steel in subsea flexible and steel risers in the area of an outer sheath/coating damage. The innovation displaces oxygenated seawater from the region of the damage and replaces it with a noncorrosive gel.

Study Evaluates Offshore Coating Performance on Stainless Steel

The objectives of the study were to develop a protocol for testing protective coating performance on pitted SS, evaluate how various surface preparation methods affect the coating performance on pitted SS, and determine a reliable coating application procedure to cover the pits with a holiday-free film so the integrity of offshore pitted SS is improved.

Surface Inhibitors Preserve Reinforced Steel Concrete Structures

Surface-applied corrosion inhibitors, which penetrate the concrete and form a protective film on the steel rebar, have successfully reduced the rebar corrosion rate and extended the service life of many types of reinforced concrete structures.

Inorganic Coating System Halts Corrosion Under Insulation in Oil, Gas Assets

A major oil and gas operating company recently revised its engineering standards to include a novel water-borne spray coating system to protect against both atmospheric corrosion and corrosion under insulation (CUI).

Lasers Could Replace Sanding, Blasting for U.S. Air Force

U.S. Airmen with the 60th Maintenance Squadron (MXS) at Travis Air Force Base in California, USA are one of two bases currently testing a pair of lasers as a new method of removing paint and corrosion on aerospace ground equipment. They say their traditional method involves the use of an orbital sander or blasting machine.

Corrosion Management of Steel Anaerobic Digesters, Sludge Tanks

Fermentation and oxidation processes used by anaerobic digesters in biomass plants can create a perfect recipe for corrosion, both at the gas and liquid phase. Sludge tanks also face similar issues.

Exploring Differences in Epoxy and Polyurethane Floor Coatings

Experts with a coatings specialist company explain the differences between floor coating systems based on polyurethanes and epoxies, and why the selection often depends on jobsite location. With each system offering differing properties suited to specialized uses, choosing the wrong solution can lead to costly repairs or even complete floor failure down the line.

U.S. Scientists Develop New Oil-Resistant Filter Technology

Researchers at the U.S. Department of Energy’s Argonne National Laboratory are working on the development of a new oil-resistant filter technology to prolong the life of equipment in industries such as oil and gas. The new invention consists of a type of coating that produces thin films of oil-repelling molecules on the surface of filter membranes. According to the researchers, the metal oxide molecules grab onto any loose water atoms while resisting oil.

Hot, Hot, Hot: Insulating the Inside of a Digester Complex

With the construction of a new digester complex for a Williston, North Dakota, USA wastewater treatment plant, it was imperative that the walls and pipes be properly insulated. Unfortunately, the insulation and pipe wrapping line item was accidentally missed on the bid.

Development of WC-Ni Cermet Brazing Process

In this case study, the serviceable lifetime of an impeller with an applied WC-Ni brazing layer on the surface measured almost eight times longer than an unbrazed impeller.

Cruise Ship Tests Surface Prep Kit to Boost Maintenance Efficiency

A novel corrosion control prevention kit utilizing shrouded surface preparation tools and demonstration videos is designed to improve the efficiency of in-house maintenance crews for maritime assets. Chris Patenaude, director of maritime and industrial sales at the company and also a NACE International-certified Coating Inspector Program (CIP) Level 3 Inspector, witnessed many common pitfalls firsthand in his prior role as global fleet superintendent for coatings and linings at cruise line operator Royal Caribbean International (Miami, Florida, USA).

Novel Design, Coatings System Resists Weathering at Tropical Complex

The combination of a unique architectural design finished with fluoropolymer coil coatings is geared to provide seacoast corrosion protection for upscale condominiums in Florida. The unique climate concerns to the region prompted an innovative concept from globally renowned architecture company Bjarke Ingels Group (Brooklyn, New York, USA).
