Formulators in the Field: The Effect of Over-Cure or Under-Cure of Polyclamine Cured Epoxy Linings

Product Number: 41216-993-SG

Author: Mike O’Donoghue, Vijay Datta, Travis Gafka

Publication Date: 2016

$20.00

Advanced technology high performance tank linings are often applied by plural spray equipment and occasionally one of the components could be off ratio. Worse still, some well-intentioned field personnel might add more curing agent to speed up the cure, or alter other properties, or may not utilize the entire curing agent portion in a single leg application. This paper investigates the effects of under-cure or over-cure on the performance of two high temperature tank linings by deliberately mis-mixing the two components.

Increasing Weathering Test Acceleration Through higher Irradiance

Product Number: 41214-873-SG

Author: Allen F. Zienik

Publication Date: 2014

$20.00

While real time outdoor weathering exposures in benchmark climates, such as South Florida, are highly recommended for determining coating performance and service lifetimes, the lengthy test times required are often problematic. Therefore, outdoor and laboratory artificial accelerated weathering testing has become a mainstay in coatings testing, particularly in the product development phase.

Isocyanate Free Polyurthane Coatings for Industrial Metal Applications

Product Number: 41215-921-SG

Author: Paul Popa, John Argyropoulos, Yanxiang Li, Nahrain Kamber, Jeff Anderson

Publication Date: 2015

$20.00

Two component polyurethane coatings are used in a variety of applications including industrial maintenance. These coating systems were introduced in the 1970’s primarily as topcoats; characterized by their excellent weatherability, toughness, and chemical and stain resistance. When formulated as ambient cured systems, traditional two component polyurethanes typically sacrifice cure time for pot life unless plural component application equipment is employed.

New Splash Zone Sulfur Containing Polyamidoamine Epoxy Type Coating

Product Number: 41208-403-SG

Author: Jim Byers, Ryan Rose, David Young, Marty Utterback, Mitch Refvik, Leonid Rapoport

Publication Date: 2008

$20.00

This presentation will compare and contrast several anti-corrosive tidal zone coatings developed under a Navy SBIR program. Requirements for the coating included no VOC’s, surface tolerance to chlorides and water, fast cure to avoid washout by tides and waves, and thick build properties. Various trials of the material on dock sheet pilings and cooling tower fallout zones will be illustrated as well as accelerated lab test data.

Past Versus Present - Comparing Laboratory Performance of Vinyl Resin Coatings with Modern Epoxy-Polysiloxane Coating Systems

Product Number: 51217-076-SG

Author: David Tordonato, Bobbi Jo Merten, Allen Skaja

Publication Date: 2017

$20.00

Starting in the 1940’s, solution vinyl resin coatings were used extensively to protect steel structures in fluctuating immersion service from corrosion. However, these systems fell out of favor when more restrictive volatile organic compounds regulations were implemented in the 1990’s. Since then, traditional epoxy systems have become a workhorse in the protective coatings industry. Unfortunately, these materials tend to degrade in sunlight, and experience has revealed their service life to be suboptimal compared to legacy coatings systems such as vinyls

Performance Evaluation of One-Coat Systems on New Steel Bridges - Final Results

Product Number: 41211-622-SG

Author: Pradeep Kodumuri, Yuan Yao, Seung-Kyoung Lee

Publication Date: 2011

$20.00

In an effort to address cost issue associated with shop application of conventional 3-coat systems, FHWA completed a study to investigate the performance of eight one-coat systems and two control coatings for corrosion protection of highway bridges. Based on prior performance, a three coat system and a two coat system were selected as the control coating systems.

Polyurea Thick-Film Elastomeric Coating/Lining Systems Accelerated Weatherometer Testing vs. Real Life Exposure

Product Number: 41210-565-SG

Author: Dudley J. Primeaux II

Publication Date: 2010

$20.00

For years, people have relied upon a variety of industry accelerated testing methods in order to predict how long a coating / lining system may be useful in service. This type of testing would include heat aging, Atlas Cell immersion testing for lining products and accelerated weatherometer testing for coating systems, just to name a few. Polyurea spray applied elastomeric materials have been no exception to this type of testing. One of the most important testing evaluations has been accelerated weatherometer exposure for products used in outdoor application areas.

Setting the Color Straight

Product Number: 41214-871-SG

Author: John W. Winfrey

Publication Date: 2014

$20.00

For years, accelerated weathering test equipment has been utilized to showcase performance of coatings as a means to justify changing to new and “better” materials. While an accelerated weatherometer is useful in confirming a material’s performance, the results can be misleading in certain situations, resulting in misguided decisions based on a marketing department’s zeal to secure additional sales.

Studying Impact on Variation of Scribe Method in Accelerated Corrosion Testing

Product Number: 51323-19351-SG

Author: James D. Begley, Victor Georgic, Suprita Jharimune, Qi Zheng

Publication Date: 2023

$20.00

Accelerated testing of corrosion-resistant coatings is a critical tool used in the development of protective coatings. Tests such as ASTM B117, ISO 12944, ISO 9227, etc. are commonly used to predict the long-term viability of these coatings in exposure times of months rather than years or even decades. While this type of testing gives meaningful results and is essential to the research and development of new technology, results can often be hard to accurately analyze due to the levels of variability inherent to accelerated testing.

The Atlanta Hyatt Restoration: An unlimited range of color and texture for concrete utilizing masonry staining.

Product Number: 41208-419-SG

Author: Russell Gray

Publication Date: 2008

$20.00

The Atlanta Hyatt boasts 1,260 guest rooms and just over 180,000 square feet of ballroom and exhibit space. Using the construction technology and trends of the time, the exterior surfaces of the hotel were constructed of exposed river rock aggregate consolidated concrete walls. This was a popular building material, but one that often left gaps of uneven areas where the river rocks were not evenly distributed.
