Introduction Adhesion is an important physical characteristic of applied coating films and systems, and testing is frequently used as an indicator to whether an adequate bond exists between the substrate and primer (first coat) and/or between coats in multiple coat applications. Adhesion testing may be a requirement of a coating specification, or may be used […]

Introduction Efficient handling of materials is vital to the steel fabricating and coating shop processes. These facilities typically employ powered industrial trucks, overhead and gantry cranes, and slings to move tons of materials such as steel within the confines of a building, between buildings, and to/ from transportation vehicles. Material handling is not done without
Ken Trimber (KTA President) moderates as Bill Corbett (KTA COO) and Jim Machen (KTA Sr. Coatings Consultant) debate the merits of using inorganic vs. organic zinc rich primers. This 33 minute podcast finds Mr. Machen promoting the use of organic zinc rich primers, while Mr. Corbett supports the use of inorganic zinc rich primers. The

Introduction Surface profile is defined as a measurement of the maximum peak-to-valley depth generated by abrasive blast cleaning and impact-type power tools. These operations effectively increase the surface area and provide an “anchor” for the applied coating system. The surface profile depth must be compatible with the total coating system thickness; typically, the thicker the

Introduction The International Agency for Research on Cancer (IARC) classifies beryllium and beryllium compounds as carcinogenic to humans, and the Environmental Protection Agency (EPA) classifies inhaled beryllium as a possible carcinogen. Despite its toxicity, beryllium is an important material in the aerospace, electronics, energy, telecommunication, energy, medical and defense industries due to its physical properties,
Designed to assist the coatings engineer or specifier in identifying candidate protective coating systems for specific service environments applicable to a broad array of industries, this guide provides the following. Commonly used generic coating systems. Service life for each in specific environments. Current material costs. Current field and shop painting costs. Guidelines for calculating approximate
This Month’s Case Was Selected From Several Investigations Related To Failures That Occur When Applying Coating To The Underside Of Metal Deck Panels (Fig. 1). This Case Focuses On An Adhesion Failure Of Coatings Applied To Previously Painted Deck Panels. A paint contracting company was hired to apply an epoxy ester dry-fall coating to portions
The Construction Specifications Institute (CSI) provides a format for preparing specifications that is often adopted for use in the coatings industry. It contains three primary sections, including General, Products and Execution. The Products section typically contains the specified coating system. There are several ways that a coating system can be specified, one of which is
