Polyurea Coatings Protect Aging Concrete Wastewater Infrastructure

Advanced polyurea coatings and liners can provide strong, flexible waterproofing to bridge cracks and protect against future cracking and deterioration.

Corrosion-Resistant Thermal Spray Coatings Withstand Supercritical CO2 Environments

Researchers have concluded that HVOF-sprayed coatings comprised of UNS R50250, UNS N10276, UNS N06625, and UNS S31603 can provide a cost-effective corrosion mitigation method for infrastructure likely to be in contact with a mixture of wet supercritical CO2 and H2S.

Medical Device Industry Turns to Plasma-Applied Coatings

To upgrade legacy medical devices under new regulations, the medical device industry is aggressively investigating and applying plasma-applied coatings to products such as stainless steel guide wires, catheters, stents, and vascular surgical tools.

Evaluation and Repair of a Liquid Sulfur Holding Tank

This case study presents the results of evaluations and repairs made to a sulfur tank at a gas plant in central Alberta, Canada. The repairs exceeded the owner’s expectations for performance and have not required any subsequent concrete repairs of significance.

Corrosion Basics: Coating New Construction Seagoing Vessels

Surface preparation and coating application during the new construction of a vessel compose a complex orchestration that requires the coordination of every department in a shipyard. It is also one of the most expensive parts of building a new vessel.

Innovative Polymeric Solution for Flanged Pipework Protection

Flanged pipework can be isolated from corrosive environments by using a flexible, liquid-applied elastomeric material that can be peeled off for inspection and then resealed.

New Mexico’s Iconic Steel Bridge Turns 50

In September 2015, when the iconic Rio Grande Gorge Bridge reached its 50th year of service, it coincided with the bridge’s biennial inspection that scrutinizes the entire structure for coating failure, corrosion, cracks in the steel, and other structural integrity issues.

High-Performance Spray-Applied Waterproofing Protects Concrete and Steel

Coating failure has led to significant degradation of America’s structural elements. As an alternative to more traditional materials, new high-performance, spray-applied waterproofing alternatives are being used to protect and maintain critical infrastructure

New Standards Provide Maintenance Guidelines for the Electric Power Industry

NACE International and the Institute of Electrical and Electronics Engineers (IEEE) have joined together to provide joint industry standards that address above-grade and below-grade corrosion of steel transmission and distribution structures.

Composite Repair Material Bonds to Poor Substrate on Historic Vessel

This former combat vessel suffered from numerous leaks and a pitted surface. It needed a long-term coating repair solution capable of bonding to a poor substrate with rapid curing times.

Guide Helps Estimate Cost and Service Life for Protective Coatings

The practical guide was designed to help coatings engineers or specifiers determine candidate protective coating systems for particular industrial environments.

Trailer Study: Wax Coating Shows Promise in Resisting Corrosion

Salt spray exposure tests revealed the strength of wax-based coatings in withstanding exposure to sodium chloride (NaCL) as a corrosive agent in truck and trailer manufacturing operations.

Protecting a Pipeline When Its Coating Has Aged

The country’s existing pipeline infrastructure was built with materials that are no longer used today, although they were state-of-the-art at the time. Coating materials, for example, have significantly improved over those used decades ago.

The Science Behind Field-Applied Liquid Epoxy Pipeline Coatings

Field-applied liquid epoxy coatings have moved from the shadows to become one of the most important methods of pipeline corrosion protection. This article presents the science behind this essential process for protecting underground pipelines from corrosion.

Assessing the Risk of Coating Failure from Residual Soluble Salts

Residual soluble salts are contaminants on a substrate surface that affect coating performance. The primary soluble salts that the coatings industry must manage are in the form of chlorides, sulfates, and nitrates.
