Two-Coat Inorganic Coating System for Corrosion Resistance
AI summary Read the abstract
Researchers examined a two-coat inorganic coating system — comprising a zinc-rich primer and a zinc-free silicate topcoat — for corrosion protection of offshore wind towers. The silicate resin is low in carbon and does not contribute to microplastic accumulation in the ocean, offering a more environmentally compatible approach to extending wind tower service life.
Extending the service life of an offshore wind tower brings value to the owner and reduces environmental impact. Zinc-rich primers are the primary strategy for corrosion protection and extending service life. In recent years, silicate topcoats made without zinc have entered the market to create a two-coat inorganic system offering superior corrosion protection. The silicate resin is low in carbon and won’t contribute to microplastic accumulation in the ocean. This article addresses a two-coat, inorganic, corrosion-resistant coating system by examining its function, application, and how it extends the life-cycle of wind towers by inhibiting corrosion for decades.

Method development for the analysis of coating/paint particles from offshore wind farms in sediment samples
AI summary Read the abstract
Researchers developed analytical methods for detecting and characterising coating and paint particles released from offshore wind farm (OWF) structures — including corrosion protection coatings and rotor blade leading edge erosion — in marine sediment samples. The study addressed methodological challenges arising from inconsistent classification of paint particles as microplastics and the lack of standardised analysis protocols for this underinvestigated source.
