This article focuses on those areas of coatings technology where silicon-based technology (SBT) is the primary enabling technology and where SBT is used as an additive to provide unique properties to the coating film. It describes the chemistry and the uses of alkoxy silanes. The uses of silicates, siliconates, silicone fluids, and silicone resins in coatings are reviewed. The article discusses the various applications of SBT, namely, primers, heat-resistant coatings, industrial maintenance coatings, hygienic coatings, and abrasion-resistant coatings, and for marine biofouling control. It also provides information on the benefits of silicon-base additives.

This article focuses on marine coatings associated with protecting commercial and military vessels. It provides detailed information on the common issues and requirements encountered when coating ballast tanks, freeboard, topside, and decks of the vessel. The article describes the advent of ultra-high solids coatings technology, and reviews the marine-specific coatings such as antifouling and their mechanisms and common failure modes.

This article discusses the main materials and water chemistry characteristics of the primary and secondary water circuits of a pressurized water reactor (PWR). It reviews the corrosion issues of PWR materials and the influence of corrosion and fouling on primary and secondary circuit radiation fields. The article explains the primary side intergranular stress corrosion cracking (IGSCC) in different materials, namely, nickel-base alloys, high-strength nickel-base alloys, low-strength austenitic stainless steels, and high-strength stainless steels. The secondary side corrosion in steam generator including denting, pitting, intergranular attack and IGSCC is also discussed. The article examines laboratory studies that have resulted in models and computer codes for evaluating and predicting intergranular corrosion, and considers the remedial actions for preventing or arresting intergranular corrosion. It concludes with information on the external bolting corrosion in nuclear power reactors.
