Epoxy vs Polyurethane Coating: Which Is Better for Steel Structure Projects?

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 […]

Corrosion Resistant Coating for Steel Structures: A Complete System Guide

A corrosion resistant coating is not a single product — it is a layered system where each coat performs a defined engineering function, and total performance depends on how those layers work together under real service conditions. Specifying “epoxy coating” without defining whether it serves as primer, intermediate build coat, or topcoat is the most […]

Polyurethane vs. Polysiloxane Topcoat: Which is Best for Marine Decks?

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 […]
