No Magic Number: Coating Concrete After 28 Days

by R. A. Nixon, Corrosion Probe, Inc.

Historically, the coatings industry has specified 28 days of cure time for concrete before coatings are applied. This 28-day curing period was designated to address two key concerns: cement paste shrinkage continuing after coating application resulting in the formation of cracks and excess moisture unnecessary for cement hydration escaping from the substrate and causing problems at the coating/concrete interface. The author examines this “magic” number and presents real-world cases.


Ceramic Epoxy Coatings in Immersion

by Ben Rowland, Induron Protective Coatings, Inc.

The term "ceramic epoxy coatings" refers to an epoxy binder with ceramic media used as a pigment/filler. This article explores ceramic epoxy coatings for use in water storage, wastewater and pipeline applications and examines properties and characteristics that differ from traditional epoxies used in these environments.


The Effect of Caustic Soda Solutions on Fusion-Bonded Epoxy Coatings at High Temperatures

by Hassan Al-Sagour and Mana Al-Mansour, Saudi Aramco

In the article, “Qualification Tests for High-Temperature FBE Coatings” in the July 2018 issue of JPCL, the results of qualification testing of high-temperature fusion-bonded epoxy (FBE) coatings were reported by the authors. Three candidate products were immersed at a high temperature and all showed satisfactory performance in distilled water, synthetic sea water and a 5-percent NaCl solution. Most products, however, experienced severe discoloration when immersed in a 5-percent NaOH (caustic soda) solution. In this article, the authors describe further testing conducted on one of the candidate products to determine the significance of this discoloration.
