Nanoparticles, microscopic particles with at least one dimension less than 100 nm, are a part of everyone’s daily life. You don’t have to be involved in their manufacture to be exposed to nanoparticles. Walking down the street we are exposed to vehicle exhaust (man-made nanoparticles); while on vacation at the beach everyone has come in […]

Alkali-silica reaction (ASR) is often the cause of debonding and blistering of epoxy coatings; however, the presence of ASR gel doesn’t necessarily mean that it is responsible for any degradation. Near-surface alkali reaction (NSAR) gel has been reported to have much the same effects. Like ASR, it appears as blistering in the low permeability surface […]
