The Formation of Amine Exudate (Blushing) of Epoxy Coatings

2 Comments / Coatings, Lab Testing / By

Epoxy coatings are some of the most widely used materials in industrial and marine environments. Epoxy materials typically have excellent adhesion, chemical resistance and water resistance, which make them first-rate candidate coatings/linings for these environments. Epoxies are formulated as two component materials, with one component housing an epoxy resin and the other component containing a

The Missing Piece: Collaborations Between Field Investigators and Laboratory Chemists

1 Comment / Coating Failure, Coatings, Lab Testing / By

Chances are, you have seen at least one procedural cop drama over the years. These shows all tend to follow a fairly standard formula: the crime occurs, the investigator is called in, the investigator gathers clues and interviews suspects, evidence is sent to a laboratory to confirm or refute theories, and by the end of

The Significance of the Permeability of Paints

Buildings, Commercial, Concrete Walls, Lab Testing / By

Permeability of Applied Paints & Coatings… Do I want a permeable coating or not? The answer to the question posed is based on the substrate and the service environment. All paint and coatings are permeable to water, just to different degrees. A high resistance to permeability is likely desirable for lining applied to the interior

Contradictory Information in a Project Specification – F-Files: Mechanisms of Failure

4 Comments / Coating Failure, Coatings, Lab Testing / By

The wastewater industry poses some of the most significant corrosion protection challenges for industrial protective coatings. In this case study, coating failure in the form of peeling and delamination (on concrete) and blistering (on steel) was observed on the interior of a digester at a wastewater treatment facility after only five years of service. Removal

Coating Failure Analysis Series – Part 6 – Laboratory Forensic Analysis

3 Comments / Coating Failure, Coatings, Concrete Floors, Lab Testing, Video / By

This is a six-part video series that demonstrates the field and laboratory methods that were used to determine why a new coating system applied to a previously painted concrete floor had failed. Each part is standalone, addressing a different aspect of the evaluation, but when viewed in order, they present a systematic step-by-step process for
