What the window really rules out, how to measure it on site, and why the coldest hour decides the schedule.https://www.rich-tech-coatings.com/en/news-atmospheric-splash-immersed-zone-coatingshttps://www.rich-tech-coatings.com/en/news-atmospheric-splash-immersed-zone-coatingsMon, 12 Oct 2026 08:00:00 +0800TechnicalThe same steel structure can sit in three corrosion environments at once. Each one loads the coating differently, and one system rarely covers all three well.https://www.rich-tech-coatings.com/en/news-carbon-intensity-rules-hull-coating-decisionshttps://www.rich-tech-coatings.com/en/news-carbon-intensity-rules-hull-coating-decisionsSun, 11 Oct 2026 08:00:00 +0800IndustryCarbon rules and fuel penalties are pushing owners to treat hull coatings as a fuel-saving asset rather than a maintenance line item.https://www.rich-tech-coatings.com/en/news-longer-service-life-coating-spec-trendhttps://www.rich-tech-coatings.com/en/news-longer-service-life-coating-spec-trendSat, 10 Oct 2026 08:00:00 +0800IndustryNewbuild and industrial tenders increasingly ask for 25 years to first major maintenance. What that shift changes in system selection, film build and shop-floor practice.https://www.rich-tech-coatings.com/en/news-c5m-steel-primer-selectionhttps://www.rich-tech-coatings.com/en/news-c5m-steel-primer-selectionFri, 09 Oct 2026 08:00:00 +0800Selection guideZinc-rich epoxy, zinc silicate or zinc-free epoxy? How to pick the primer layer for C5-M and offshore steel by service life, surface prep and recoat window.https://www.rich-tech-coatings.com/en/news-zinc-rich-epoxy-vs-inorganic-zinc-silicatehttps://www.rich-tech-coatings.com/en/news-zinc-rich-epoxy-vs-inorganic-zinc-silicateThu, 08 Oct 2026 08:00:00 +0800Selection guideBoth are zinc primers, but they behave very differently on site. A side-by-side comparison of preparation demands, curing, recoat windows and where each one wins.https://www.rich-tech-coatings.com/en/news-wet-film-dry-film-volume-solidshttps://www.rich-tech-coatings.com/en/news-wet-film-dry-film-volume-solidsWed, 07 Oct 2026 08:00:00 +0800TechnicalWhy the same 200 µm specification can mean different paint consumption on two products, and how volume solids drives your material estimate and cost per square metre.https://www.rich-tech-coatings.com/en/news-recoat-interval-and-overcoating-windowhttps://www.rich-tech-coatings.com/en/news-recoat-interval-and-overcoating-windowTue, 06 Oct 2026 08:00:00 +0800ApplicationApplying the next coat too early causes solvent entrapment; too late causes intercoat adhesion failure.

Both have to be specified, checked and recorded — most adhesion failures start here.https://www.rich-tech-coatings.com/en/news-mio-intermediate-coat-purposehttps://www.rich-tech-coatings.com/en/news-mio-intermediate-coat-purposeSun, 04 Oct 2026 08:00:00 +0800TechnicalMicaceous iron oxide is not a filler. It changes how the film behaves under UV, in thick build-ups and at edges — and it is often the layer that decides whether the system survives.
