In recent years, there has been great focus on the preservation of aging infrastructure and extending the service life of assets in oil and gas, marine, power generation, water, and other corrosion affected industries. There has been increasing demand for surface tolerant and easy-to-apply rehabilitation coatings that will meet the most stringent industrial requirements and standards. Most existing anticorrosion coating solutions have high standard surface treatment and application requirements which are not suitable for in-service assets. In addition, most commercial offerings require the complete removal of the previous coating system, some of which, require special disposal procedures due to HSE concerns and regulations. To address the need for an innovative solution to satisfy this industry demand, a multi-functional polymeric coating has been developed. The new corrosion protection system is easy-to-apply requires minimum surface preparation, and is able to encapsulate its residual coatings. This coating system has been engineered for the additional functionalities of UV light resistivity for environmentally exposed assets and vibration absorption resulting in sound dampening,
reducing noise pollution. A comprehensive study was conducted using conventional and nonconventional
test methods based on current industrial standards and performance specifications to evaluate the value proposition of this new coating system. Environmental and thermal shock results show excellent protection against corrosion and durability under changes in temperature. Salt spray results according to ISO 9227 and ISO 12944-2 successfully passed 720 hours of testing at category C4 (high) in the durability scale with the coating remaining intact with no corrosion creep observed at the edges of coated panels. Furthermore, thermal aging of this coating system has demonstrated a calculated lifetime of over 25 years. This new coating system was engineered through software-guided mixture design-of-experiments (DOE) followed by extensive evaluation under simulated field conditions with the detailed results for this novel cold applied coating system presented herein.

Abrasive material forms a major component for surface preparation in coating applications. Since blastin
g method developed in 1890s, abrasive materials and its application methods also significantly improve
d to enhance blasting efficiency. In general, steel grit and shot ball are being used predominantly as me
tallic abrasives. Garnet and coal slag are used as non-metallic abrasives. Each abrasive is selected and
applied in accordance with the work location and substrate material of structures to be coated. In this st
udy, we have evaluated a new artificial non-metallic abrasive (ferrochrome slag) which is a by-product fr
om ferrochrome production process for stainless steel. This evaluation also included the checking of sur
face cleanliness performance and coating quality based on international test methods and field trials. Fo
r verifying the cleanliness quality, various tests were conducted as per international standards (ISO 850
1-8503). Sea water immersion test (ISO 2812-2) and cyclic test (ISO 12944-9) were carried out to check
coating performance after blasting. The field test results indicates that all inspection and quality criteria o
f surface preparation were met as per international standards. Furthermore, coating performance test re
sults also showed this abrasive does not have any adverse effect on coating properties.

Inorganic zinc-rich coatings (IOZ’s) are often considered the gold standard for corrosion protection in atmospheric environments. Frequently, zinc epoxy coatings are considered second best among the most effective coatings for corrosion protection. However, current zinc-rich coating technology is not exempt of limitations, such as poor mechanical properties of the film, rigid environmental application conditions, or the inefficient use of zinc particles for providing galvanic protection. Due to these limitations, a number of asset owners have made the decision not to use zinc-rich coatings to maintain coating systems in marine and offshore environments
