Lab Testing

IntroductionThere are a wide range of immersion environments where protective coatings (liquid or powder), sheet materials, or rubber linings may be expected to protect an asset. Some of the environments range from basic water immersion to chemical immersion with perhaps high pressure and elevated temperatures. The most widely protected assets are constructed of concrete and […]

 “What kind of paint should I get?” There is no one answer to this question because there are many different situations that would need to be considered, along with personal preferences.  Anyone who has ever walked into a paint store or paint department of a home improvement store can easily become overwhelmed by the sheer

Introduction Pigments play a critical role in paint and coatings. Insufficient or excess quantities of pigments can adversely impact the appearance and performance, so it is important to be able to reliably measure the percent of pigment in the formulated product. Furthermore, due to differences in paint types, there are various methods for quantifying the

Introduction One of the more frequently asked questions when it comes to testing the tensile strength of industrial protective coatings is, “What glue should I use to attach the loading fixture?” This brief article lists the standard test methods for evaluating tensile adhesion and describes some of the considerations when selecting an adhesive. Standardized Test

Pavement marking materials are relied upon to not only to guide drivers to maintain their respective lane position to deter accidents but also for regulatory and directional purposes. Because of their functions, they must withstand many different types of wear and still perform as required. This article describes pavement marking materials including the different types

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 environments that are notoriously challenging. The use of accelerated weathering/corrosion testing in the laboratory to differentiate coating performance is still viable, but can take a year or longer, versus
