Two-Coat Inorganic Coating System for Corrosion Resistance

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.
