Self-Stratifying Environmentally Friendly Alkyd Coatings

Product Number: 51216-005-SG

Author: Ryan R. Salata, Mark D. Soucek.

Publication Date: 2016

$20.00

The current process for coating large metal substrates, such as the decks of naval ships, requires pretreatment, primer, and topcoat steps. Developing a coating that can combine these steps into one would significantly reduce the labor costs and application time, which are significantly more expensive than the coating itself. This research shows the development of a self-stratifying alkyd coating.

Stray Current Corrosion Risks and Case Histories in Communication Tower and Electric Transmission Applications

Product Number: 51320-14770-SG

Stray current refers to electric current that flows elsewhere rather than along its intended path. Stray current is a well-known factor in pipeline maintenance and has been discovered to be an important consideration in communication and electric transmission structure maintenance. Corrosion caused by stray current is frequently many magnitudes greater than corrosion that occurs naturally in soil. Stray current may accelerate corrosion on guy anchors of communication towers and electric transmission towers which could lead to reduced service life or catastrophic failure.

In this paper, stray current corrosion risk for galvanized guy anchors is discussed in detail. Identification by structure-to-soil potential measurements is discussed. Stray current case studies are presented. Overall, this paper demonstrates that while stray current corrosion is a significant risk for guyed telecommunication and electric power structures, it can be detected and mitigated. This paper is an overview of the commonly accepted practices of stray current detection and mitigation used today.

The Importance of Sample Taking in Failure Analysis

Product Number: 41207-392-SG

Author: Dwight G. Weldon

Publication Date: 2007

$20.00

Regardless of the sophistication of the laboratory, the ability to determine the cause of a coating failure can depend on the type and quality of the samples. This paper discusses the type of samples needed and gives suggestions on how to obtain them.
