Steel Preparation

Steel [Metal] Preparation (For purposes of this Technical Note, painting and coating are interchangeable. Also, this Technical Note deals with carbon steel, stainless steel, and other ferrous metals only. Preparation of non-ferrous metals is dealt with separately.) General Discussion: The life of a coating depends as much on the degree of surface preparation as on…

SL/75™ Tensile Bond Strength

VersaFlex SL/75™ Fascia Bond strength vs. Tensile strength VersaFlex SL/75™ tensile strength, nominally reported under ASTM D412 at 620 psi, develops sufficient strength against cohesive failure (material ripping apart internally) to cause fascial disbondment from the concrete joint (tensile strength of the concrete at the joint fascia, 300-600 psi) when joint expansion stresses develop. We…

Salts 101: An Overview

Salts 101: An Overview Soluble salts are very much at the forefront of discussion in the coatings industry. There is much information available on the topic, but often is provided in small segments so a complete comprehension is not easy to grasp. It is the purpose of the following to provide an overview to assist…

Moisture In Concrete

Moisture In Concrete: Understanding its Effects on Coatings Moisture, pH, and Alkalies: Freshly placed Portland Cement has a pH level of 12.5 (highly alkaline); it will provide passivation of embedded steel. Carbon Dioxide and ambient air react, meaning that: Over time, concrete pH will reach 8.5 Carbonizing starts from the surface and moves down at…

Irradiation Evaluation of Polyurea

Irradiation Evaluation of Polyurea Spray Elastomers 100% Solids, two-component polyurea spray elastomer systems are being utilized in a wide variety of application areas. In most cases, the systems are exposed to typical environmental conditions with excellent performance. A recent interest has been in coating applications where levels of nuclear radiation may be present. To evaluate…
