Step-Change Epoxy Coatings for Pipes, Tanks, Vessels and Railcars

by Dr. Mike O’Donoghue; Vijay Datta, Ms and Dr. Ian Fletcher, International Paint LLC.

The authors describe the genesis and performance of a step-change epoxy coating for high heat-resistant service and CUI mitigation. Based on a novel amine epoxy technology platform, this next generation high-temperature coating simplifies coating specifications and is easy to apply on carbon and stainless-steel pipe externals for both insulated (CUI) and non-insulated service. Tolerant of over-application and possessing fast and sub-zero curing characteristics, the novel alkylated amine epoxy coating enhances shop productivity and reduces project costs, thereby eliminating several challenges seen with traditional epoxy phenolic coatings.

Enhancing the UV Durability of Epoxy Coatings: Waterborne Acrylic-Epoxy Hybrid Coatings for Steel

by Hank Bernacki, Zhenwen Fu, Bingquan Li, Denise Lindenmuth and Leo Procopio, The Dow Chemical Company

The challenge with epoxy chemistry is maintaining all of the excellent coating properties such as adhesion, corrosion resistance and chemical/solvent resistance while improving upon its weaknesses such as flexibility, potlife and UV durability. The Type III acrylic/epoxy systems improve upon UV durability, but with slow cure speed and property development. This article describes a new acrylic-epoxy hybrid polymer technology for 2K waterborne coatings that addresses these issues.

Getting Down to Earth With Elevated Work Platforms

by Michael Halliwell, Thurber Engineering Ltd.

If you’ve spent any amount of time on a construction site, there are two pieces of equipment that you are bound to see: the lowly, but ever present, skid-steer loader (or “Bobcat”) and an elevating work platform (EWP). This article examines EWPs and how to use them safely.
