Hydrophobic Elastometric Coatings for Chemical Resistant Linings

Hydrophobic Elastometric Coatings for Chemical Resistant Linings

Corrosion mitigation by the use of barrier coatings relies on polymers and other substances to minimize the permeation of corrosive agents to the substrate. To achieve good barrier properties, most protective coatings rely on high crosslinking density and special fillers to increase the tortuosity of the film. However, this approach usually leads to highly viscous and brittle coatings that take too long to cure. In contrast, flexible and tough coatings typically do not have the requisite barrier properties for enhanced corrosion prevention.

Corrosion mitigation by the use of barrier coatings relies on polymers and other substances to minimize the permeation of corrosive agents to the substrate. To achieve good barrier properties, most protective coatings rely on high crosslinking density and special fillers to increase the tortuosity of the film. However, this approach usually leads to highly viscous and brittle coatings that take too long to cure. In contrast, flexible and tough coatings typically do not have the requisite barrier properties for enhanced corrosion prevention. Here, we demonstrate the role of hydrophobicity in the barrier properties of coatings by comparing the chemical resistance of fast cure hydrophobic elastomeric coating against epoxy coatings typically used in chemical resistance applications. Our results show that increased hydrophobicity reduces the mass uptake of corrosion-inducing chemicals (such as acids and bases) and thus improves the corrosion-prevention properties of the coatings. Further, these coatings are able to withstand chemicals, including organic chemicals like gasoline and ethanol, at elevated temperatures. Finally, our cathodic disbondment testing data as well as moisture vapor transmission data show that these coatings have exceptional barrier properties. Overall, we show that the hydrophobicity of a coating can have a strong influence on its barrier properties and these principles can be used to create next generation corrosion resistant coatings.

(Insulation & Corrosion) Insulative Coatings - Fit for Purpose

Product Number: 17-COAT_DEC21
Author: Arin Shahmoradian
Publication Date: 2021

Corrosion Under Insulation (CUI) is a very serious problem impacting the oil and gas, petrochemical, power and heavy industries. Due to the high costs associated with CUI, many industries have begun abandoning conventional jacket insulation. Recent advancements in trade association standards have helped engineers select, apply and inspect different types of insulative coatings in lieu of conventional jacket insulation.
