Electrochemical Impedance Spectroscopy (EIS) can be a useful tool for differentiating today’s high-performance coating systems. These advanced coatings with their improved barrier properties perform longer in-service environ...
Introduction For decades, traditional aliphatic acrylic polyurethane topcoats were the mainstay as finish coats for exterior environments where resistance to solar radiation (sunlight) was desired to preserve color and gloss and p...
Introduction The hardness of a coating material is a relative property that may be interpreted in a variety of ways by different industries that use coating/lining materials. While hardness testing is frequently used to assess th...
The oil and gas production and distribution industry presents unique challenges associated with protective coatings performance. Recently, a group of environmental activists, armed only with bolt cutters, broke into valve stations...
Section loss of pipe wall is of great concern in the pipeline industry. Reduced wall thickness due to pitting corrosion can adversely impact pipeline integrity; the results of which can be catastrophic depending on the product tha...
Many agencies and facility owners require coating testing of products and systems prior to their use on a coating project. This is not an original concept; developing a qualified products list (or QPL) is becoming more commonplace...
When conducting a coating failure investigation, the investigator’s first inquiries should be “What was supposed to be done,” and “Does it make sense?” The answers to these questions are typically revealed in the specification for...
Gas transmission lines are often specified to be coated in a shop using fusion bonded epoxy (FBE) coating systems. These coatings are chosen for the resistance to chemicals, the ease of back filling due to the impact resistance, ...
Many important industrial coatings are two- or even three-component products (also referred to as two-pack, 2K, or three-pack, 3K) in which a chemical reaction between the components results in a coating film. The components are p...
