Let’s Talk About In-Process and Post-Application Adhesion Testing
We discuss post-application adhesion testing of liquid-applied protective coating systems and in-process adhesion testing of thermal spray coatings.
We discuss post-application adhesion testing of liquid-applied protective coating systems and in-process adhesion testing of thermal spray coatings.
Learn about the proper use of the SSPC visual guide for abrasive blast cleaning and how it may be used to assist in creating a project-specific surface cleanliness standard.
Learn about destructively measuring coating thickness using a Tooke gage (or similar device) according to Procedure A in ASTM D4138
We explore various methods of testing an IOZ primer for cure prior to overcoating. Inorganic zinc-rich primers are used on newly fabricated steel in the shop and frequently dry very quickly but may not cure for days unless there is sufficient airborne moisture available to react with the ethyl silicate binder.
Continuous read/scanning technology is readily available and can be specified when a project would benefit from a greater population of thickness measurements to help ensure consistency of the applied coating across large surfaces.
The relative hardness of an applied coating or lining can be quantified using Pencil Hardness (thin film coatings) or Durometers (thick film coatings).
Regardless of which party you are working for, documentation of inspection data is a critical role for a trained/certified inspector, albeit oftentimes one of the more dreaded tasks.
Product data sheets are a valuable tool for coating applicators as well as trained and certified coating inspectors. They are essentially an instruction manual for using the product. Unfortunately, many of us don’t read the instructions until it is too late.
It’s easy to fall behind on the latest updates in the coatings industry. That’s why KTA focuses on education to help keep AMPP and FROSIO coating inspectors current on standards, inspection practices, new instruments, and more. This first volume of the Certified Coating Inspector Forum, written by KTA’s COO William Corbett, is a compilation of …
This article describes the importance of surface soluble salt testing and explores the various methods of extraction and analysis that can be performed in the shop or field.
