PPG Showcases Two New Protective Coatings at China Coatings Show 2020
PPG PITT-CHAR NX is the next-generation flexible epoxy intumescent coating system that is designed for the most severe hydrocarbon hazards, including pool fires, jet fires and explosion. The system substantially reduces both the thickness and weight of passive fire protection (PFP) coating, allowing for lower cost and significantly faster application. PPG SIGMAGLIDE 1290 silicone-based fouling release coatings offer superior anti-fouling performance that reduces speed loss, improves power and minimizes environmental impact.

Hexion CEO Returns from Medical Leave Due to COVID-19
Hexion said that Craig Rogerson, chairman and CEO, has returned to work from a medical leave of absence, effective immediately. CFO George Knight, who served as interim CEO in Rogerson’s absence, will resume his prior role. In late March, Hexion announced that Rogerson will take a medical leave of absence “due to a condition consistent with COVID-19.”

OAP Coating and Lining Systems: For Petroleum and Water Storage Tanks
By Deborah V. Simmons, Johnny C. Pourciau and Murray Heywood, Sherwin-Williams Protective & Marine
The use of coating systems formulated with optically active pigments can help to ensure correct application and inspection of interior linings for petroleum and water storage tanks. This article explains how OAP technology can help identify pinholes, eliminate holidays and reduce premature failures often caused by inadequate film thickness on angles, edges or areas that are difficult to inspect.

Field Testing for Soluble Salts: A Problem to Be Aware Of
By Simon Hope, Auquharney Associates Ltd.
The presence of soluble salts on a surface is a major factor in premature breakdown of protective coatings, and resultant increased maintenance costs for the asset owner. This article explains why the presence of salts are a problem, how to measure for salts on a surface, industry standards on the subject and the results of a case study involving salt detection and removal.

Micaceous Iron Oxide – The Barrier Effect- Shingle Effect Pigment
MIO coatings are made with micaceous iron (MIO) pigment, a very dark coloured, layered mineral with a subtle metallic lustre. The flake-like shape of MIO pigments is the key to their protective powers. Like tiny mirrors, they reflect the UV light, protecting the underlying resin against chalking. While iron oxide is chemically stable and excellent at preventing corrosion, MIO takes it to the next level. Compared to the spherical pigments more commonly used in paints and coatings, MIO’s overlapping flat layers create a near impossible barrier for water, salt or other damaging molecules.

TESTING AND FAILURE ANALYSIS
Critical Questions for Protective Coatings for Asset Protection in Oil& Gas, LNG:
• Why is the coating not stopping corrosion?
• Why is the coating delaminating or blistering?
• Has the coating been correctly specified / applied?
• Does the coating meet the manufacturing standard, including properties such as correct hardness/cure, adhesion and thickness?
• What surface preparation and atmospheric conditions must be achieved to successfully apply the coating?
• Does the coating have any defects in it? How will these affect performance?
• Why did the coating fail? Root cause assessment.
• How can the coating be successfully repaired/remediated so that it doesn’t fail again?
ExcelPlas Labs can answer these questions

ExcelPlas Labs – The Leaders in Evaluation and Assessment of Protective Coatings
Electrochemical Impedance Spectroscopy (EIS) is a powerful and sensitive tool to detect the condition of a coated metal. This technique can generate quantitative data relating to the quality of a barrier coating and the plot of data can be used to indicate the status of coating long before any visible damage occurs. EIS can also be used as a post-evaluation tool to indicate the barrier property or any change in the coating after the test exposure, such as QUV exposure, Autoclave test, Atlas Cell test, Salt Fog or Immersion test, etc.
