Insights & technical notes
Selection guides, technical explainers, application notes and industry updates — written around the long-tail questions buyers and applicators actually search for.
Atmospheric, splash and immersed: three coating problems
The 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.
Read moreHow carbon intensity rules are reshaping hull coating decisions
Carbon rules and fuel penalties are pushing owners to treat hull coatings as a fuel-saving asset rather than a maintenance line item.
Read moreWhy 25-year coating specifications are becoming the norm
Newbuild 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.
Read moreHow to choose a primer for C5-M steel structures
Zinc-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.
Read moreZinc-rich epoxy vs inorganic zinc silicate
Both 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.
Read moreVolume solids: converting wet film to dry film thickness
Why 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.
Read moreRecoat intervals: the window most projects get wrong
Applying the next coat too early causes solvent entrapment; too late causes intercoat adhesion failure. How to read recoat tables and plan around weather and yard logistics.
Read moreSurface preparation grade and profile: two different things
Sa 2½ is a cleanliness grade; roughness is a separate measurement. Both have to be specified, checked and recorded — most adhesion failures start here.
Read moreWhat the MIO intermediate coat actually does
Micaceous 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.
