Эпоксидное против полиуретанового покрытия: что лучше для проектов стальных конструкций?

Epoxy and polyurethane are not “either-or” in most steel structure projects—engineers usually specify them together: epoxy for corrosion barrier and build, polyurethane for UV/weathering and appearance as the finish coat. ISO 12944-5 notes that most epoxy coatings chalk when exposed to sunlight and recommends applying a suitable topcoat if color or gloss retention is required, which […]

Что такое антикоррозийная система покрытия? Полное руководство для стальных конструкций

An anti-corrosion coating system is not a single paint—it is a layered system (primer + intermediate + topcoat) designed to protect steel from corrosion under specific environmental exposure and service life targets. ISO 12944 describes protective paint systems for steel in different corrosivity categories and links system choice to durability (service life) expectations. What Is an Anti-Corrosion […]

Полиуретан против полисилоксана: какое лучше для морских палуб?

For marine decks and offshore topsides, the “best” topcoat depends on what is killing your coating first: UV weathering, abrasion/traffic, chemical splash, or maintenance access. ISO 12944-5 notes that most epoxy coatings chalk in sunlight and that if color or gloss retention is required, a suitable topcoat should be applied—this is why polyurethane and polysiloxane are common final-coat choices […]
