Performance Testing of Exterior Wood Coatings

Wood is one of the most utilized building materials for exterior structures. Like most exterior substrates, wood structures need protection from the environment. While some wood types are naturally resistant to the environment (e.g., cedar) and some wood is treated with chemicals to preserve its integrity (wolmanized timber), paints and coatings are used to both …

The Formation of Amine Exudate (Blushing) of Epoxy Coatings

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 …

Evaluating a Coating’s Resistance to Cathodic Disbondment – Guidance on Selection of Test Methods

Installation of a coating to a cathodically-protected pipeline or structure without first testing its resistance to cathodic disbondment can result in catastrophic failure of the coating. However, there are over twenty international standard test methods to evaluate a coating’s inherent resistance to cathodic disbondment; each with its own set of parameters and materials, which can …

Consequences of Applying Coatings Outside of the Recommended Thickness Range

When recommending a coating or coating system for a specification, or when responsible for the application of a coating, the manufacturer’s Product Data Sheet (PDS) should always be consulted.  The PDS typically contains information regarding appropriate uses and environments, performance characteristics, and application information including mixing, application methods and equipment and the recommended thickness range …
